I upgrade my installation from 2.1 to 2.2. Whenever I save an xtend file, the builder creates the following log entry and no java file is generated. Do you need more information? org.eclipse.xtext.builder.impl.XtextBuilder - java.lang.NullPointerException at org.eclipse.xtext.xbase.compiler.ImportManager.appendType(ImportManager.java:70) at org.eclipse.xtext.xbase.compiler.StringBuilderBasedAppendable.appendType(StringBuilderBasedAppendable.java:101) at org.eclipse.xtext.xbase.compiler.StringBuilderBasedAppendable.append(StringBuilderBasedAppendable.java:23) at org.eclipse.xtext.xbase.compiler.AbstractXbaseCompiler.compile(AbstractXbaseCompiler.java:195) at org.eclipse.xtext.xbase.compiler.JvmModelGenerator.generateBody(JvmModelGenerator.java:742) at org.eclipse.xtext.xbase.compiler.JvmModelGenerator._generateMember(JvmModelGenerator.java:499) at org.eclipse.xtext.xbase.compiler.JvmModelGenerator.generateMember(JvmModelGenerator.java:1130) at org.eclipse.xtext.xbase.compiler.JvmModelGenerator$1.apply(JvmModelGenerator.java:168) at org.eclipse.xtext.xbase.compiler.JvmModelGenerator$1.apply(JvmModelGenerator.java:1) at org.eclipse.xtext.xbase.lib.internal.FunctionDelegate.apply(FunctionDelegate.java:40) at com.google.common.collect.Lists$TransformingRandomAccessList.get(Lists.java:451) at java.util.AbstractList$Itr.next(AbstractList.java:345) at com.google.common.collect.Iterators$7.computeNext(Iterators.java:644) at com.google.common.collect.AbstractIterator.tryToComputeNext(AbstractIterator.java:141) at com.google.common.collect.AbstractIterator.hasNext(AbstractIterator.java:136) at org.eclipse.xtext.xbase.compiler.JvmModelGenerator.generateBody(JvmModelGenerator.java:181) at org.eclipse.xtext.xbase.compiler.JvmModelGenerator.generateType(JvmModelGenerator.java:96) at org.eclipse.xtext.xbase.compiler.JvmModelGenerator._internalDoGenerate(JvmModelGenerator.java:87) at org.eclipse.xtext.xbase.compiler.JvmModelGenerator.internalDoGenerate(JvmModelGenerator.java:1105) at org.eclipse.xtext.xbase.compiler.JvmModelGenerator.doGenerate(JvmModelGenerator.java:76) at org.eclipse.xtext.xtend2.ui.builder.XtendBuilderParticipant.handleChangedContents(XtendBuilderParticipant.java:46) at org.eclipse.xtext.builder.BuilderParticipant.build(BuilderParticipant.java:168) at org.eclipse.xtext.builder.impl.RegistryBuilderParticipant.build(RegistryBuilderParticipant.java:60) at org.eclipse.xtext.builder.impl.XtextBuilder.doBuild(XtextBuilder.java:160) at org.eclipse.xtext.builder.impl.XtextBuilder.incrementalBuild(XtextBuilder.java:141) at org.eclipse.xtext.builder.impl.XtextBuilder.build(XtextBuilder.java:91) at org.eclipse.core.internal.events.BuildManager$2.run(BuildManager.java:728) at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:42) at org.eclipse.core.internal.events.BuildManager.basicBuild(BuildManager.java:199) at org.eclipse.core.internal.events.BuildManager.basicBuild(BuildManager.java:239) at org.eclipse.core.internal.events.BuildManager$1.run(BuildManager.java:292) at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:42) at org.eclipse.core.internal.events.BuildManager.basicBuild(BuildManager.java:295) at org.eclipse.core.internal.events.BuildManager.basicBuildLoop(BuildManager.java:351) at org.eclipse.core.internal.events.BuildManager.build(BuildManager.java:374) at org.eclipse.core.internal.events.AutoBuildJob.doBuild(AutoBuildJob.java:143) at org.eclipse.core.internal.events.AutoBuildJob.run(AutoBuildJob.java:241) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:54)
I couldn't reproduce it. What version of Eclipse do you use and what's the qualifier of the 2.2 build you have?
Also your OSGi-Manifest (or class path configuration) would be interesting.
it seems like you have the old cbae lib on the class path (i.e. Exceptions) is not found. We'll make this more robust. Thanks.
Created attachment 208161 [details] eclipse configuration dump This configuration lists the complete classpath of my running Eclipse installation. Maybe this answers some version questions.
Is there a simple way how I can make it work? Uninstall/clean/reinstall doesn't solve it. What does "cbae" stand for? Which lib should I update/exchange?

Sorry, it should have been 'xbase'. You need to make sure, to have org.eclipse.xtext.xbase.lib in version 2.2.0 on your classpath.
I.e. update your target platform.
thx. solved.
