Description

When using groovy-eclipse-compiler with Maven command line and an IBM JDK the maven-compiler-plugin fails with the following error message
(I'm using groovy-eclipse-compiler 2.5.1-M3, because of http://jira.codehaus.org/browse/GRECLIPSE-1142)

I have attached a simple test project which will work when compiling (mvn compile) with a Sun/Oracle jdk, but will fail with a IBM jdk. When imported into eclipse (with groovy-eclipse plugin) everything compiles no matter what jdk is used. Included in the test project is a java test case which will force the NoClassDefFoundError given above. The error stems from org.codehaus.jdt.groovy.integration.LanguageSupportFactory.tryInstantiate()'s line
JavaCore javaCore = JavaCore.getJavaCore();
The JavaCore-class imports org.eclipse.jdt.internal.core.JavaModelManager, which implements IContentTypeManager.IContentTypeChangeListener. The latter class is not included in the groovy-eclipse-batch jar-file. A possible workaround is to add the following dependency:
<dependency>
<groupId>org.eclipse.core</groupId>
<artifactId>org.eclipse.core.contenttype</artifactId>
<version>3.4.100.v20100505-1235</version>
</dependency>
(when verbosing class loading with a Sun/Oracle jdk the JavaModelManager is never loaded. Is the Sun/Oracle jdk's class loading fundamentally different from IBM's? Lazy class loading of some kind?)

Thanks for the detailed explanation of the problem and a workaround. I'll have a look at this today. Perhaps the solution is to always depend on the contenttype bundle. However, this is a shame since this makes the size of the dependencies even larger.

Given that GRECLIPSE-1142 has been resolved, is there any reason why you are still using M3?

No reason - I see now that 2.5.1-1 is available with this fix included (I thought I had to wait for 2.5.2). Perhaps the Groovy documentation should be updated (http://groovy.codehaus.org/Groovy-Eclipse+compiler+plugin+for+Maven )?

Just to make sure...your build is working fine when you add the extra dependency? That bundle 92kb and is small enough that I can just include it inside the groovy-eclipse-batch artifact.

But perhaps a better approach is to split up the groovy-eclipse-batch artifact and instead depend on the eclipse artifacts. I'll have to play around with this a bit, but I do want to make sure that the current workaround is sufficient for you.

It works when adding the dependency. I have also tested that an exclusion of all the transitive dependencies works:
<dependency>
<groupId>org.eclipse.core</groupId>
<artifactId>org.eclipse.core.contenttype</artifactId>
<version>3.4.100.v20100505-1235</version>
<exclusions>
<exclusion>
<artifactId>org.eclipse.equinox.preferences</artifactId>
<groupId>org.eclipse.equinox</groupId>
</exclusion>
<exclusion>
<artifactId>org.eclipse.equinox.registry</artifactId>
<groupId>org.eclipse.equinox</groupId>
</exclusion>
</exclusions>
</dependency>
