MWE2 workflow with xpand2.Generator and Beautifier fails [message #894933]

I've added

postprocessor = org.eclipse.xpand2.output.JavaBeautifier

to the outlet of my Generator component. When I run it, I get:

java.lang.IllegalStateException: [XtextLinkingDiagnostic: null:21 Couldn't resolve reference to JvmType 'org.eclipse.xpand2.output.JavaBeautifier'.]

I guess, there's some kind of classpath problem but as the component itself works, classes from org.eclipse.xpand2 seem to be okay. Any ideas?

Hi Martin!

Yes, this indicates a classpath problem. But you are also right that if the class Generator is found, also JavaBeautifier should be found, since they are bundled both in the org.eclipse.xpand plugin. Anyway, check that the class is really on your classpath.

Thanks. At least I seem to be on the right track. However I rechecked the spelling and the run configuration and didn't find any mistakes. Auto-complete properly shows me the class but I still get the error.

Any specific ideas on which places to check?

How can I enable debug logging on MWE2 runs?

Thanks again!

I resolved the issue by adding the following four entries to the Require-Bundle section of MANIFEST.MF:

 org.eclipse.core.runtime;bundle-version="3.8.0",
 org.eclipse.core.resources;bundle-version="3.8.0",
 org.eclipse.jdt.core;bundle-version="3.8.1",
 org.eclipse.text;bundle-version="3.5.200"

Using the "old" xpand in new xtext2 projects seems to create a few minor problems, I guess if have to take a closer look on how xpand is integrated in xtend2...
