Steps to reproduce:

1. Edit file: maven-xtext-example/pom.xml
2. Increase version of "xtext.version" from 2.11.0 to 2.12.0
3. Start maven build
   cd maven-xtext-example
   ./mvnw package

Hi,

Would be best if the example project was using two different output folders for xtend and the hero language.

And by the way, I'm surprised that one has to explicitly tell maven to add the source folder of xtend (or hero?) and to clean it...

I know that with the xtend-maven-plugin there is no need for that, is that needed for xtext-maven-plugin? If yes... why? :)

Hi,

Problem

maven-exec-plugin 1.3 itself depends on an old version of asm (see: http://mojo.codehaus.org/exec-maven-plugin/dependencies.html).

When executing Mwe2Launcher with xtext 2.6, which relies on asm 5.0.1, common types can't detect the correct version of asm, it shows the following warning (got it just by changing all the xtext/xtend dependencies of maven-xtext-example from 2.5 to 2.6.0, and the version of maven-exec-plugin from 1.2.1 to 1.3):

0    [org.eclipse.emf.mwe2.launch.runtime.Mwe2Launcher.main()] WARN  pes.access.impl.DeclaredTypeFactory  - --- xtext.common.types ---------------------------------------------------
0    [org.eclipse.emf.mwe2.launch.runtime.Mwe2Launcher.main()] WARN  pes.access.impl.DeclaredTypeFactory  - ASM library is too old. Falling back to java.lang.reflect API.
0    [org.eclipse.emf.mwe2.launch.runtime.Mwe2Launcher.main()] WARN  pes.access.impl.DeclaredTypeFactory  - Please note that no information about compile time constants is available.
0    [org.eclipse.emf.mwe2.launch.runtime.Mwe2Launcher.main()] WARN  pes.access.impl.DeclaredTypeFactory  - It's recommended to use org.objectweb.asm 5.0.1 or better.
1    [org.eclipse.emf.mwe2.launch.runtime.Mwe2Launcher.main()] WARN  pes.access.impl.DeclaredTypeFactory  - --------------------------------------------------------------------------

Solution

For now, the solution I found is to exclude the three asm dependencies of exec-maven-plugin by adding in the dependencies the following along with the 2 dependencies to xtext and xbase:

                    <dependency>
                        <groupId>org.apache.maven.plugins</groupId>
                        <artifactId>maven-plugin-plugin</artifactId>
                        <version>3.2</version>
                        <exclusions>
                            <exclusion>
                                <groupId>asm</groupId>
                                <artifactId>asm</artifactId>
                            </exclusion>
                            <exclusion>
                                <groupId>asm</groupId>
                                <artifactId>asm-commons</artifactId>
                            </exclusion>
                            <exclusion>
                                <groupId>asm</groupId>
                                <artifactId>asm-tree</artifactId>
                            </exclusion>
                        </exclusions>
                    </dependency>

@dhuebner can you fix
https://dhuebner.ci.cloudbees.com/job/maven-xtext-example/

The example project where we use our herolanguage should show that the DSL can access Java (and Xtend) code in the same project.

This would also let us catch possible problems with the xtext-maven-plugin due to "bad" behaviors of JDT (see the signing problems of the previous 2022-06 release) and other dependency problems (as happened in the past).

Hi,

If maven package is called again without clean being called before, the following error (but which is actually warning) is shown:

 [INFO] Generating stubs into /home/victor/fac/dev/may/xtext2.5/maven-xtext-example/example-project/target/xtext-temp/stubs

                ^^^^^^^^
 [WARNING] The type Superman is already defined
 [WARNING] ----------
 [WARNING] 1 problem (1 error)

I am not exactly sure what is the difference between the stubs and the generated-sources, but maybe one of them should be removed?

Created a simple pom in the root folder (maven-xtext-example).

pom.xml

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <groupId>my.mavenized.herolanguage</groupId>
    <artifactId>my.mavenized.herolanguage.module</artifactId>
    <packaging>pom</packaging>
    <name>${project.artifactId}</name>
    <version>1.0.0-SNAPSHOT</version>

    <modules>
        <module>my.mavenized.herolanguage.releng</module>
        <module>example-project</module>
    </modules>
</project>

During maven build from the root folder (ie without changing directory into releng) the MWE2 workflow fails to find the dsl projects build.properties and MANIFEST.MF.

It looks like the mwe2 build is dependent on the path from which it is triggered.

This is very inconvenient because typically maven projects are organized into many nested multi-module builds, this way building at the root of the project tree builds all projects in it.

Is there anything that can be adjusted in the mwe2 file or the pom to get this to work?

Varghese Cottagiri

Hi,

When I built the project, I found invalid characters (like below ones) in .xtextbin file which caused to build fail (Invalid byte 1 of 1-byte UTF-8 sequence) :

塭m

Is there any way to fix it?

thanks

Hi, I'm pretty new to xText and just wonderd what it means that "If you use Xtext 2.9 or higher, the Maven build for your language is auto-generated."?

I noticed that I'm using xText 2.11.
I try to set-up a Continuous Integration using Travis CI.

Could you please quickly outline the steps of your README I should follow and which are unnecessary since version 2.9?

Many thanks! 😄

Hello! Example does not build with Java 11 because of depedencies needing Java 17:
[ERROR] org.eclipse.core.jobs 3.15.0.v20230808-1403 requires Execution Environment that matches (&(osgi.ee=JavaSE)(version=17)) but the current resolution context uses [a.jre.javase 11.0.0]

Eclipse cannot map maven-exce-plugin as it is used in my.mavenized.herolanguage/pom.xml

Adding a custom lifecycle-mapping for m2e 1.5 as described here

also doesnt help.

Hi,

I encountered below issue when I built example project. Could anyone help it out?

Hi Sven, I just tried building this from scratch and get the following error:

ERROR: HeroLanguageProposalProvider.xtend -
6: my.mavenized.ui.contentassist.AbstractHeroLanguageProposalProvider cannot be resolved to a type.

I'm running with Java 8 and maven 3.2.1.

All is in the title: the sonatype repositories are needed for the project to work.

I observe the same problem like the following
#12 with the master of maven-xtext-example project.

When I compile (mvn install) this example project I got:

[ERROR] ERROR:The type Superman is already defined in Super.hero. (file:/F:/javaee/eclipse_mars_workspace/maven-xtext-example/example-project/src/main/java/Super.model line : 1)

The workaround is mvn clean install, but when we have deals with big projects, this is not suitable workaround.

On importing the example projects into eclipse - there is this one error for the following xtend test

 9: @Test def void testSimple() {
10:   assertEquals("Hello I can fly!", new my.company.Superman().helloSuperman)
11: }

Description : my.company.Superman cannot be resolved
Resource : SuperManTest.xtend
Path : /example-project/src/test/java/my/hero
Location : line: 10 /example-project/src/test/java/my/hero/SuperManTest.xtend
Type : Xtend Problem

but the code generated is in line with the type not found issue

@Test
public void testSimple() {
    throw new Error("Unresolved compilation problems:"
      + "\nmy.company.Superman cannot be resolved."
      + "\nhelloSuperman cannot be resolved");
}

Is this something that you purposely intended to do?

Using Tychos magic version number 0.0.0 (instead of 1.0.0.qualifier) for the feature referenced in the updatesite category.xml would let Tycho replace this version number automatically during the build.

Hi,

When producing a .jar with mvn package, it seems that the .hero and the .xtend files are not included in it, only the generated one.

I'm wondering if there is a way to keep it there, either done by the maven xtext plugin, or as a configuration in the example-project project pom.

Strangely, the xtend files are present in the plugin my.mavenized.herolanguage generated jars...

Hi,
I cloned the master branch, ran mvn clean install on the parent pom and was able to get to build without issues, however trying to install the language feature into my photon IDE by pointing to the target/repository folder of the update site project i am getting the error below. Have tried it in both oxygen and photon and wondering how to resolve it. Thanks

Cannot complete the install because one or more required items could not be found.

I am trying to make this example with those updates and i can't make it work.

component = xtextgenerator{}

The implementation with that component could replace the one used in this example in the mwe2 file.

We could try to build it with Maven/Tycho to possibly spot problems (as it happened in the past) with target platform resolution

Hi,

I did a clean checkout and run a maven install in parent (my.mavenized.herolanguage.releng). If I run a mvn install in example-project, I get the following error.

[INFO] Validate and generate.
[INFO] Starting validation for input: 'Super.hero'

Any Ideas?

It is unclear how to generate an Xtext-based language with the metamodel implemented in Xcore. I gave it a try, but a mwe2 workflow that works in Eclipse fails in Maven due to trying to parse a .xcore file as XMI.

It works when xtext-2.5.0-SNAPSHOT is changed to just xtext-2.5.0 in my.mavenized.herolanguage/pom.xml

Hi,

I followed the steps from doc for building xtext projects with maven and it works OK for normal xtext projects.

My project had a custom AntlrFragment that extends XtextAntlrGeneratorFragment and it is declared in my *.mwe2 file.

When I try to build with maven, I got this: Couldn't resolve reference to JvmType parse.antlr.AntlrGeneratorFragmentWithCustomLexer

Thanks
