Hi Johannes,

Thanks for the reply. 

If I try to force Eclipse to process annotations. I get this error...

java.io.IOException: org.eclipse.core.internal.resources.ResourceException: Resource '/JEX/bin/META-INF/json/org.scijava.plugin.Plugin' does not exist.

Any idea why the file is not created on processing?

Thanks,
