Hello All, I'm working on the bug you have opened for EASE (https://bugs.eclipse.org/bugs/show_bug.cgi?id=420319). And I have encountered some issues with the build. I think that I know where it comes from but I would like to know what you think about it.
In the ease project we have an Xtext editor. In order for maven to generate the
necessary source for the build, I have added this to my pom.
<build>
<plugins>
<plugin>
<groupId>org.eclipse.xtend</groupId>
<artifactId>xtend-maven-plugin</artifactId>
<version>${xtext-version}</version>
<configuration>
<encoding>UTF-8</encoding>
</configuration>
<executions>
<execution>
<goals>
<goal>compile</goal>
</goals>
<configuration>
<!-- need to prefix by basedir
to generate to currently built module -->
<outputDirectory>${basedir}/xtend-gen</outputDirectory>
</configuration>
</execution>
</executions>
<dependencies>
<!-- these dependencies are contributed in
Eclipse by the "Xtend Library"
classpath container -->
<dependency>
<groupId>org.eclipse.xtend</groupId>
<artifactId>org.eclipse.xtend.lib</artifactId>
<version>${xtext-version}</version>
<type>pom</type>
</dependency>
</dependencies>
</plugin>
</plugins>
</build>
Which comes from :
<pluginRepositories>
<!-- Repository to resolve xtend-maven-plugin -->
<pluginRepository>
<id>xtend</id>
<url>http://build.eclipse.org/common/xtend/maven/</url>
</pluginRepository>
</pluginRepositories>
This plugin uses Antlr 3.2 to generate the source. This is available from the
Maven Central repository. However when I try to run the build on Hudson I get :
[INFO] o.h.m.e.h.MavenExecutionResultHandler - Build failed with exception(s)

My guess is that Antlr is not compatible with the Eclipse license so it has
been removed from the Central Repository. Can you confirm ?
Although I will not integrate Antlr, I just want to use it to build EASE. Is
it still illegal?
If my guess is good could you tell me how I can find out what is available from
Eclipse side.
The solution for EASE is to contribute the generated sources to git repository,
this way this plugin will not be mandatory anymore.
Thanks for your help,
Regards,
Arthur Daussy
