ceylon / ceylon-maven-plugin

Ceylon Maven plugin for compiling/running ceylon from Maven

Ceylon

This is the 1.3.4-SNAPSHOT "You'll Thank Me Later" release of the Ceylon command line tools. This is a production version of the platform.

Ceylon is a modern, modular, statically typed programming language for the Java and JavaScript virtual machines. The language features a flexible and very readable syntax, a unique and uncommonly elegant static type system, a powerful module architecture, and excellent tooling, including an awesome Eclipse-based IDE.

Ceylon enables the development of cross-platform modules which execute portably in both virtual machine environments. Alternatively, a Ceylon module may target one or the other platform, in which case it may interoperate with native code written for that platform.

Systems where Ceylon is known to work

Since Ceylon is running on the JVM it should work on every platform that supports a Java 7 or 8 compatible JVM. However we have tested the following platforms to make sure it works:

Linux

• Ubuntu "wily" 15.10 (64 bit) JDK 1.7.0_95 (IcedTea) Node 0.10.25
• Fedora 23 (64 bit), JDK 1.8.0_77 (OpenJDK)
• Fedora 22 (64 bit), JDK 1.8.0_72 (OpenJDK)
• Fedora 22 (64 bit), JDK 1.7.0_71 (Oracle)

Windows

• Windows 10 Home (64 bit) 1.8.0_77
• Windows 7 (64 bit) 1.7.0_05 (Oracle)
• Windows Server 2008 R2 SP1 JDK 1.7.0_04

OSX

• OSX 10 Lion (10.8.5) JDK 1.7.0_40 (Oracle) Node 0.10.17
• OSX 11 El Capitan (10.11.6) JDK 1.7.0_80 (Oracle) Node 0.10.35

ceylon-maven-plugin's Issues

'test' goal fails when there are no tests to run

The plugin's test goal will fail with the following message if there are no tests to run:

======================== TESTS STARTED =======================
======================== TEST RESULTS ========================
There were no tests!
[INFO] ------------------------------------------------------------------------
[INFO] BUILD FAILURE
[INFO] ------------------------------------------------------------------------

I'd say it's unexpected given that surefire will not fail in that case by default. It also forces me to enable/disable the goal manually in every project (some of them are missing tests) instead of configuring the plugin once in a parent pom, which is a pita.

I guess the problem originates from the definition of isSuccess here: https://github.com/ceylon/ceylon-sdk/blob/master/source/ceylon/test/engine/DefaultTestRunResult.ceylon#L35

Cloning the Repository and Installing the Plugin Fails on Windows

Yesterday, I tried to manually install this plugin, in order to get the latest bugfix for JDK9 support, but the build fails for me, because it is trying to find and execute mvn.bat in my PATH, although the file is named mvn.cmd, instead.

Console output: output.txt

Either explode the `.car` in `target/classes` or fix the CP for multi-modules

ATM if I have a Java module that depends on a Ceylon module in the same project, the CP of the Java project will include my-ceylon-module/target/classes which does not exist. It should either point to /my-ceylon-module/target/modules/com/foo/1/com.foo-1.car or we should explode the .car in my-ceylon-module/target/classes.

Do you plan to support javaScript compilation?

I plan to use javaScript in a project so I'm wandering if there will be support for javaScript. I'm willing to add support myself but although I know maven, and the ceylon command line and understand maven plugins, I don't have hands on experience with maven plugins.

"Maven descriptor missing in Ceylon module" with plugin versiono 1.3.2

I'm compiling the example project https://github.com/vietj/ceylon-maven-example

If I set the plugin version to 1.3.2, mvn compile fails with the following error:

Support install target

Right now, if I do mvn install I get my Ceylon module compiled, but then I get an empty jar installed:

[WARNING] JAR will be empty - no content was marked for inclusion!
[INFO] Building jar: /home/stephane/src/java-eclipse/my-app/module-ceylon/target/ceylon-1.0-SNAPSHOT.jar

[INFO] --- maven-install-plugin:2.5.2:install (default-install) @ ceylon ---
[INFO] Installing /home/stephane/src/java-eclipse/my-app/module-ceylon/target/ceylon-1.0-SNAPSHOT.jar to /home/stephane/.m2/repository/com/mycompany/app/ceylon/1.0-SNAPSHOT/ceylon-1.0-SNAPSHOT.jar
[INFO] Installing /home/stephane/src/java-eclipse/my-app/module-ceylon/pom.xml to /home/stephane/.m2/repository/com/mycompany/app/ceylon/1.0-SNAPSHOT/ceylon-1.0-SNAPSHOT.pom

I think we should hook into the install phase to install the compiled .car and probably use the pom that is inside the .car.

Which pom.xml to use to publish the module is tricky: the pom.xml written by the user doesn't need to have its dependencies correctly set, since they're declared in module.ceylon, but the rest of the info is valid: groupId, artifactId, etc…

The generated pom.xml inside the .car has valid dependencies but generated groupId/artifactId and such.

So ATM both are problematic. Either the plugin should verify that the dependencies are in sync. Or the compiler. The IDE could sync both files. Or we forget about syncing deps, and we add a compiler flag to point to our pom.xml so that it will fetch missing info from there, such as groupId, artifactId, parent and fill in the dependencies by itself.

I think that last option is saner and will lead to more correct pom.xml files, no?

Maven failing to compile (maybe transitive dependencies)

Trying to configure my ceylon-spring-boot example with maven does not compile.

• If run just ceylon compile & ceylon run it does work, but when i tried mvn compile

Tool errors missing unless `verbose` is set

I had this error: "ceyloncTask: target release 7 conflicts with default source release 1.8" which made the build fail but I had no idea why it failed until I set verbose to true. That's not helpful at all. We should print the tool's stderr/out on error.

When running on Java 7, error due to source language.

I think the Maven compile task will add -source 1.8 to the compile task by default, which takes precedence to the 1.7 default we detect from the running on Java 7, leading to this error: ceyloncTask: target release 7 conflicts with default source release 1.8.

I think we should get rid of that, or at least set it with -target 1.8 to be consistent.

Skip phase for run goal

It would be useful to have a tag for run goal (for instance if that is used for running tests).

Don't create defaults for configuration that's defined in `.ceylon/config`

Currently we set boolean values such as fullyExportMavenDependencies in the CompilerConfig even if the user did not specify them, thereby overriding the values from .ceylon/config which is wrong.

Include instructions for integration with eclipse

The project worked great and really made things easier. I think it would help eclipse newbies if you included an eclipse section in the documentation that explained that they should do the following:
right click on the project and click configure>convert to ceylon.
Also, in order to run a ceylon program in eclipse you must first right click on the project and click build path. then navigate to ceylon Build>build paths. Then change the output folder at the bottom of the window from target to target/classes. Finally, click apply.

Add test targets

We should compile tests under src/test/ceylon, and run them in the test phase.

Static Metamodel

It would be nice if there was an option to generate static metamodel.
