Hi,
my pom.xml for the maven compiler plugin looks like this:
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.8.1</version>
<configuration>
<compilerId>eclipse</compilerId>
<source>1.8</source>
<target>1.8</target>
<encoding>UTF-8</encoding>
</configuration>
<dependencies>
<dependency>
<groupId>org.codehaus.plexus</groupId>
<artifactId>plexus-compiler-eclipse</artifactId>
<version>2.8.1</version>
</dependency>
</dependencies>
But running mvn clean verify results in following error: MYFILE:[57] System cannot be resolved
I've simply followed the instructions here
Any idea why the compiler can't resolve System?
Regards
Hello
Currently, the plexus-csharp-compile is taking src/main/java as the default source directory. Making src/main/csharp the default directory would let csharp compiling phase activated within a profile by
<profile>
<id>csharp-comp</id>
<activation>
<file>
<exists>${basedir}/src/main/csharp</exists>
</file>
</activation>
</profile>
instead of
<profile>
<id>csharp-comp</id>
<activation>
<file>
<exists>${basedir}/src/main/java</exists>
</file>
</activation>
</profile>
which is misnamed
Eclipse will soon release its next version (4.5 Mars). Its compiler provider better compatibility with Java 8.
I will create a pull request for this as soon as ecj 4.5 is available on maven (scheduled for June 24).
Hello,
Currently it is not possible to issue an:
mvn clean package
due to a the following error:

I am not very good at English
I want use my own jar . It is in /src/main/webapp/WEB-INF/lib/myJar.jar
when i use this
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.1</version>
<configuration>
<source>1.7</source>
<target>1.7</target>
<encoding>UTF-8</encoding>
<compilerArguments>
<verbose />
<bootclasspath>${env.JAVA_HOME}/jre/lib/rt.jar</bootclasspath>
<extdirs>${project.basedir}/src/main/webapp/WEB-INF/lib</extdirs>
</compilerArguments>
</configuration>
</plugin>It is works! /src/main/webapp/WEB-INF/lib/myJar.jar can be ues 。
But for some reason i must use plexus-compiler-eclipse，like this:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.1</version>
<configuration>
<source>1.7</source>
<target>1.7</target>
<encoding>UTF-8</encoding>
<compilerId>eclipse</compilerId>
<compilerArguments>
<verbose />
<bootclasspath>${env.JAVA_HOME}/jre/lib/rt.jar</bootclasspath>
<extdirs>${project.basedir}/src/main/webapp/WEB-INF/lib</extdirs>
</compilerArguments>
</configuration>
<dependencies>
<dependency>
<groupId>org.codehaus.plexus</groupId>
<artifactId>plexus-compiler-eclipse</artifactId>
<version>2.2</version>
</dependency>
</dependencies>
</plugin>when it use this option in my pom.xml,it not works!
So when I use plexus-compiler-eclipse to compile my project, how to use my own jar!
Think you!
Sometimes it is difficult to set up the plugin configuration in a way to support different JDKs (maybe even using toolchains). For example look at MPOM-264. To ease that the JavacCompiler should only use the -release parameter with version 9 or above as using it with earlier versions leads to errors.
An additional condition should be added to
Adding an option that can cause all of the output generated by Javac could make users better able to figure out what is happening when they face issues such as #37 and #20 and increase their confidence in depending on this code.
While fixing such parsing issues is good, there is nothing to prove the parsing is perfect or nothing to prevent the output from changing and breaking the parsing in the future, just this option would continue to be useful.
If I do a version bump from 2.8.8 to 2.9.0, I get the following stack trace:

Any help is appreciated.
Hello,
Good day. I have a maven project having the maven compiler plugin 2.5.1 for compiling the source during the build. When the JAVA_HOME variable points to JDK 8 installation directory (C:\DevEnv\ProgramFiles\Java\jdk1.8.0_20), im getting the error message Unable to locate the Javac Compiler in C:\DevEnv\ProgramFiles\Java\jdk1.8.0_20..\lib\tools.jar . The same runs with the Java 7 without any problem.
Observations :
when debugged, it ended up in the file JavacCompiler.java of artifact plexus-compiler-javac. The line System.getProperty( "java.home" ) in the compile process outputs differently for Java 8 and Java 7
For Java 7 - C:\DevEnv\ProgramFiles\Java\jdk1.7.0_80\jre
For Java 8 - C:\DevEnv\ProgramFiles\Java\jdk1.8.0_20
can you provide a fix to this ?
I first reported this issue on the Maven Compiler Plugin (https://issues.apache.org/jira/browse/MCOMPILER-407) and it was suggested that the fix needs to happen here first.
Certain Java annotation processors and compiler plugins like The Checker Framework can print useful diagnostics on stdout. Currently, there is no way to see this output using the Maven Compiler Plugin, even when Maven is run with the -X option. I suggest that when Maven is in debug mode, there should be a debug message printed with the full stdout of the Java compiler. This should also work if the compiler is forked.
If someone points me at the relevant code, I am happy to try to submit a pull request for this change.
Hi, it would be fine to also have a compiler implementation for the J2ObjC framework ( http://j2objc.org/ ). I've began to do one that i will contribute when it will be usable, it is hosted on my fork of your repo but it's just a POC right now.
When the javac of Java 6 (6_45) finds a class file with newer version number, it aborts the build with the following error on STDERR:
bad class file: com\modern\Offending.class(com\modern:Offending.class)
class file has wrong version 52.0, should be 50.0
Please remove or make sure it appears in the correct subdirectory of the classpath.
import com.modern.Offending;
^
It seems plexus-compiler is not able to parse this error. When running the maven-compiler-plugin, this is silently swallowed and the user is left guessing why her build failed...
Newer version of Java (tested with Java 7_60) just show a warning, which is parsed correctly.
So if your JDK is 8 and you have a 8, it should be ignored. This allows for parent POMs to be specified that can be used both with Java 8 or earlier, and Java 9 or later.
The current source tree appears to expect that J2ObjC will be installed and fails to build if it is not available.
Either J2ObjC should be made optional or J2ObjC should be pulled as a dependency automatically. At minimum the requirements for installed components needed to build plexus-compiler should be specified as the failure is quite opaque.
The error-prone compiler doesn't respect the actual toolchain in the Maven build. For example: if I launch Maven with JDK 9, but the toolchain is set to JDK 8, error-prone will still use JDK 9's javac.
Hi,
I'd like to know is there some examples to show how to use csharp compiler?
I followed the official website and can only find the settings in pom.xml:
<plugin>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.8.1</version>
<configuration>
<compilerId>csharp</compilerId>
</configuration>
<dependencies>
<dependency>
<groupId>org.codehaus.plexus</groupId>
<artifactId>plexus-compiler-csharp</artifactId>
<version>1.8</version>
</dependency>
</dependencies>
</plugin>
Then, I put my .cs file into src/main/java and run mvn compile, error message is :
Fatal error compiling: This compiler doesn't support in-process compilation. -> [Help 1]
I tried to put my .csproj file under the same folder but the error still exists. ( do I still need the .csproj file ? If not ,how to claim dependencies in pom.xml?)
My OS is MacOS and install the dotnet SDK by following https://code.visualstudio.com/docs/languages/csharp
Many Thanks.
This is because of the bug1 and bug2. Although it can be fixed immediately by the eclipse team, I think they will not fix it. The bug2 was reported 7 month ago and two new version released. A workround is using processormodulepath instead of processorpath. ( Perhaps introduce side effect. ) However, the maven does not support processormodulepath option. So the workaround should be placed in the plugin.
For example the plugin provide an option to decide whether processorpath should be replaced with processormodulepath.
It is possible to have both --process-module-path and --process-path, so the configurationConfiguration should support both options. Thsi is similar to the separation of classpath and modulepath, where e.g. the maven-compiler-plugin is responsible for dividing the jars over both paths.
[WARNING] Error injecting: org.codehaus.plexus.compiler.javac.errorprone.JavacCompilerWithErrorProne
java.lang.NoClassDefFoundError: org/codehaus/plexus/compiler/javac/InProcessCompiler
but it fails compilation with

With this hint the caller can decide which classes should be (re)compiled. In general if incremental compilation is not supported, it is best to recompile everything if something has changed.
(Since Compiler is an interface, this requires Java 8 so a default method can be added)
I have a modular javafx project and would like to use ecj, so I configured it in my pom:

</dependencies>
I immediately get lots of errors, both concerning missing modules (e.g. cannot find javafx.controls) and types within my own module that cannot be resolved (classes in the same package). When running maven (with javac) and the -X options I see that maven itself seems to be aware of the modules and that the information is passed along to javac:

There is no trace of the modules in the command line options. Inspecting the code, this isn't surprising as the code doesn't seem to look for or handle module-path related stuff. I assume the maven's module path information is available, so wonder why it's not used?
It is currently not possible to pass argument files to javac like so:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<compilerArgs>
<!-- NOPE! 😢 -->
<arg>@somefile</arg>
</compilerArgs>
</configuration>
</plugin>The reason is that JavacCompiler creates its own temporary argument file, including @somefile but recursive @s are not supported by javac. The obvious (only?) solution would be to give the compiler a separate option for argument files that are not included into the temporary one, e.g:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<!-- strawman syntax! -->
<compilerArgFiles>
<argFile>@somefile</argFile>
</compilerArgs>
</configuration>
</plugin>Per Robert Scholte https://issues.apache.org/jira/browse/MCOMPILER-367 can only be fixed in this plugin.
Here is the problem description:
I will attach a testcase showing the following problem.
If you compile a project that has compiler warnings, javac's output indicates which Xlint option will suppress the warning. But when compiling the same code under this plugin, this vital information is suppressed so the user has a difficult time figuring out which option to use.
Expected behavior: output should indicate which Xlint option corresponds to the warning.
Running mvn compile on the testcase results in:
[INFO] — maven-compiler-plugin:3.8.0:compile (default-compile) @ testcase —
[INFO] Changes detected - recompiling the module!

I then run the following compilation:
javac -d C:\Users\Gili\Documents\3rdparty\testcase\target\classes -classpath C:\Users\Gili\Documents\3rdparty\testcase\target\classes; -sourcepath C:\Users\Gili\Documents\3rdparty\testcase\src\main\java;C:\Users\Gili\Documents\3rdparty\testcase\target\generated-sources\annotations; -s C:\Users\Gili\Documents\3rdparty\testcase\target\generated-sources\annotations -g -target 11 -source 11 -encoding UTF-8 com\company\SomeClass.java module-info.java
I get:
module-info.java:2: warning: [module] module not found: someOtherModule
exports com.company to someOtherModule;
^
1 warning
Notice that the javac output includes "[module]" at the beginning of the warning message. This indicates that "-Xlint:-module" will suppress this warning. I am expecting maven-plugin-compiler to show this information in its output.
Please let me know if have any questions and/or would like me to attach the testcase here.

The JavacCompiler class will not configure annotation processing if the source version is < 1.6, regardless of the JDK version in use. The impact to JDK 1.6+ systems which are configured to source version 1.5 is that JavacCompiler will ignore the generated sources configurations and javac will process annotations using its default conventions.
In my environment, I am using Maven with JDK 1.8 and targeting Java 1.5 source. I would expect sources generated by annotation processors to be generated in the maven-compiler-plugin default generated sources directory (${project.build.directory}/generated-sources/annotations), but plexus-compiler never passes the -s flag to javac so the sources are instead generated in ${project.build.outputDirectory}.
There's an update on http://openjdk.java.net/jeps/261 where the new arguments have been renamed to the GNU style convention
I am working on adding a showLint option to maven-compiler-plugin (https://issues.apache.org/jira/browse/MCOMPILER-442)
When I add a get/setShowLint() members to CompilerConfiguration the simple-javac test fails due to:
491:[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.1:compile (default-compile) on project simple-javac: Execution default-compile of goal org.apache.maven.plugins:maven-compiler-plugin:3.8.1:compile failed: An API incompatibility was encountered while executing org.apache.maven.plugins:maven-compiler-plugin:3.8.1:compile: java.lang.NoSuchMethodError: 'java.lang.String org.codehaus.plexus.compiler.CompilerConfiguration.getShowLint()'

As the 3.8.1 compiler does not know about this option. When build skipping tests and install the plexus-compiler API 3.8.9-SNAPSHOT and then build a maven compiler plugin 3.9.0-SNAPSHOT which uses the plexus-compiler API 3.8.9-SNAPSHOT I can execute the tests by using that version in plexus-compiler-its/src/main/it/simple-javac/pom.xml but the circularity is problematic.
@olamy How can I introduce a new CompilerConfiguration without breaking the integration tests?
Since 2.8.6 it reads the files with default charset:
Try compiling the attached file when default charset is ISO-8859-1.
Utf.java.txt
The current way the Eclipse compiler adapter works prevents the use of a custom -log argument.
Trying to use plexus-compiler-eclipse 2.9.0 with maven-compiler-plugin 3.8.1 leads to
org.apache.maven.plugin.PluginContainerException: An API incompatibility was encountered while executing org.apache.maven.plugins:maven-compiler-plugin:3.8.1:compile: java.lang.NoSuchMethodError: 'java.lang.String org.codehaus.plexus.compiler.CompilerConfiguration.getWarnings()'

plexus-compiler-eclipse 2.9.0 depends on plexus-compiler-api 2.9.0, but doesn't declare this dependency in the pom.xml. So one ends up with inconsistent versions.
Users would have to override the maven-compiler-plugin config by not only adding the dependency to plexus-compiler-eclipse:2.9.0 but also to plexus-compiler-api:2.9.0.
I think the dependency should be declared.
Recently the support of -parameters was added and the idea is that it should just ignore the parameter when running on a pre Java8 runtime.
It looks like the assertion can be improved as a build with Java7 fails if the parameters flag is provided. I guess it's related with the fact that the source and version have been (wrongly) set on 1.8 on a JDK7 runtime. Is there a way to check we're running with a JDK7 compiler?
-target 1.8 will fail with a more explicit exception but because we set an invalid flag we don't have the chance to reach that point :(

This is triggered by the Stack Overflow question No verbose output when fork option is used for maven-compiler-plugin.
The JavacCompiler is ignoring the standard output of the javac executable (thus ignoring the verbose configuration) when used in forked mode.
This is because in the method compileOutOfProcess, the CommandLineUtils.StringStreamConsumer out variable populated with the standard output is ignored when populating the resulting messages:
returnCode = CommandLineUtils.executeCommandLine( cli, out, err );
messages = parseModernStream( returnCode, new BufferedReader( new StringReader( err.getOutput() ) ) );
As suggested fix, the parseModernStream method should take both the result of the error output and standard output.
While trying out Error Prone, the compilation failed because one of our other annotation processors required an extra jar on the classpath. JavacCompiler.parseModernStream ignores annotation processor exceptions, making it very hard to figure out what went wrong.
This is the forked Javac's output:

</plugin>When debug logging is turned on Javac Plexus compiler creates two additional files in target/classes or target/test-classes. These files will be also included in the built artifact, say a JAR file.
This is done here:
And here:
Seems that the calls to config.getOutputLocation() need to be replaced with config.getBuildDirectory() in those two instances.
Hi
It seems that org.codehaus.plexus:plexus-compiler-csharp:2.8.7 is buggy while
org.codehaus.plexus:plexus-compiler-csharp:2.8.6 is fine.
See 2.8.6.log versus 2.8.7.log
For implementing Maven issue MNG-4660 we would like to be able to know when the last compilation happened. We need this information to determine the packaged artifact (.jar) is up-to-date with the compiled sources (in target/classes usually).
For now we will look through all target/classes files to check their lastModified time, but if we could use the lastModified time on the target/classes directory, we could improve performance a lot.
On Unix based systems, the target/classes directory will (if I remember correctly) be updated to the time of compilation, but for Windows it isn't.
https://stackoverflow.com/questions/12249155/how-to-get-the-last-modified-date-and-time-of-a-directory-in-java
So my suggestion is to overwrite the lastModified property on the target/classes directory after compilation.
Starting with Java 7, the Oracle version of javac (probably also applies to OpenJDK, etc.) places the "symbol" and "location" lines after the line terminating in the ^ character. As a result, the parsing logic in JavacCompiler discards potentially important compiler output for the last message that is printed (messages printed prior to the last one have the previous message's extra context prepended to their own message).
Examples:
Java 6 javac:
Error.java:3: cannot find symbol
symbol : class Properties
location: class Error
Properties p = new Properties();
^
Error.java:3: cannot find symbol
symbol : class Properties
location: class Error
Properties p = new Properties();
^
2 errors
Java 7 javac:
Error.java:3: error: cannot find symbol
Properties p = new Properties();
^
symbol: class Properties
location: class Error
Error.java:3: error: cannot find symbol
Properties p = new Properties();
^
symbol: class Properties
location: class Error
2 errors
Java 7 plexus-compiler-javac:
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.3:compile (default-compile) on project test: Compilation failure: Compilation failure:
[ERROR] Error.java:[3,2] error: cannot find symbol
[ERROR] symbol: class Properties
[ERROR] location: class Error
[ERROR] Error.java:[3,21] error: cannot find symbol
[ERROR] -> [Help 1]
Note the missing context for the last error.
I had a Java class using a builder pattern to put together a lookup table. There was another class which chained together 600+ method calls on a single line on this builder, assembling the table. Understandably, as the number of entries in the lookup table grew, we eventually ran into a StackOverflowError from javac while compiling the class. javac does not handle this gracefully; the SOE stacktrace is written to stderr with no surrounding context clues, and then the compiler exits.
The project is built using Maven, which of course uses plexus-compiler-javac. We run the build in forked mode.
Unfortunately, the Plexus compiler recognizes the forked build as failed, but does not capture the cause. There are no messages on the CompilerResult, and nothing is printed to stdout/stderr. It was therefore quite difficult for me to diagnose the cause of the compilation failure. By enabling verbose mode, I was able to see the compiler's progress, and through process of elimination I identified the problematic class. One look at the class led me to suspect an SOE, which I was able to verify by compiling the class manually at the command line. From there, it was a simple matter of splitting up the line of code into multiple lines.
I have created an MVCE here: https://github.com/jakerobb/plexus-javac-compiler-bug. It's a small Maven project. Just clone it and run mvn test to reproduce the issue.
I think that #39 would have been helpful here, but I also think that some other improvements are called for:
Of course, ideally, javac should be fixed to not throw an SOE in this scenario, probably by replacing recursion with iteration, and also to write out the file it was working on when compilation fails. I'm now off to figure out how to report an improvement request in javac....
See Eclipse bug 559645 for context and a sample Eclipse maven project showing the issue.
Basically, ECJ reports these diagnostics from APT processors as "extra_problem" elements in the log XML. plexus-compiler-eclipse completely ignores these when parsing the XML to get the diagnostics. Even if it did parse them, ECJ at least up to 3.20.0 has a bug and doesn't report the source file for these extra_problems in the XML, so the output would not be really helpful.
The following output results in no messages at all:
warning: [path] bad path element "d:\maven_repo\.m2\repository\org\ow2\asm\asm-xml\5.0.3\asm-5.0.3.jar": no such file or directory

An exception has occurred in the compiler (9). Please file a bug against the Java compiler via the Java bug reporting page (http://bugreport.java.com) after checking the Bug Database (http://bugs.java.com) for duplicates. Include your program and the following diagnostic in your report. Thank you.

I need somehow to set --no-package-directories flag, but can't find how to do that with plugin definition.
Provided example of
<compilerArguments>
<use-arc />
<sourcepath>src/main/java</sourcepath>
</compilerArguments>
doesn't allow it because of -- (double minus sign)
Using of
<compilerArgs>
<arg>-use-arc</arg>
<arg>-sourcepath src/main/java</arg>
<arg>-d target/objc</arg>
<arg>-x objective-c</arg>
<arg>--no-package-directories</arg>
</compilerArgs>
fails with The argument -sourcepath src/main/java isnt't a flag recognized by J2ObjC.
Hi,
I experienced a problem with mulitple --add-exports during my Maven build and created an issue in the Maven compiler plugin (see https://issues.apache.org/jira/browse/MCOMPILER-279).
Since the plugin works with the normal Java compiler and also the Eclipse compiler itself understands multiple add-exports arguments, he pointed me to the EclipseJavaCompiler here.
The problem is that in line https://github.com/codehaus-plexus/plexus-compiler/blob/master/plexus-compilers/plexus-compiler-eclipse/src/main/java/org/codehaus/plexus/compiler/eclipse/EclipseJavaCompiler.java#L179, the custom compiler arguments are processed as entries of a map. But here, the entries should be processed as real entry pairs. Therefore the method config.getCustomCompilerArgumentsEntries() should be used. But there is also a failing test thus a further change becomes necessary. Thus the change for line #179 would be following:
for ( Entry<String, String> entry : config.getCustomCompilerArgumentsEntries() )
{
// omit errorsAsWarnings options which already have been handled above
if ( entry.getKey().equals("errorsAsWarnings") || entry.getKey().equals("-errorsAsWarnings") )
{
continue;
}
I don't know exactly how to provide a patch or a pull request and I'm totally unsure of how to provide a unit test verifying the correct behaviour after the fix. I had a look at the existing unit tests but didn't find anything I could really base a new test case upon.
But I would give a PR a try if someone can point me to a howto, etc....
During parseMordemStream, with exitCode=4, the following message is skipped:
An exception has occurred in the compiler (1.7.0_80). Please file a bug at the Java Developer Connection (http://java.sun.com/webapps/bugreport) after checking the Bug Parade for duplicates. Include your program and the following diagnostic in your report. Thank you.
com.sun.tools.javac.code.Symbol$CompletionFailure: class file for java.util.Optional not found
As the buffer doesn't match the condition, the message will never be added in the errors list.
What is the purpose/idea/reason for that?
Maven builds fail if the following conditions are set:
module-info.javaThis results in using the module path instead of the class path of the javac compiler. Now the javac compiler also needs to be configured with --processor-module-path so that the compiler can find the required annotation processors in the processor module path. The latest version of plexus-compiler-javac only supports the --processorpath parameter of javac. This parameter is set by the maven-compiler-plugin to the default class path. But when using Java 9+ modules the class path doesn't seem to be used by javac to find the annotation processors. So, to use annotation processors in combination with Java 9+ modules, the plexus-compiler-javac needs to support the related parameter.
