Hi,

I have a JUnit test which executes an acceleo transformation in works fine when executing from Eclipse. Found here (https://github.com/deep-modeling/melanee-core/blob/master/tests/org.melanee.core.test.melanee2metadepth/src/org/melanee/core/test/melanee2metadepth/GenerateFactoryTest.java).

In my maven build I use the acceleo maven plugin to compile my template which works fine. When running my test, however, I do get a NullPointer exception in the generation process.

java.lang.NullPointerException
at org.eclipse.acceleo.engine.service.AcceleoService.doGenerate(AcceleoService.java:565)
at org.eclipse.acceleo.engine.service.AbstractAcceleoGenerator.generate(AbstractAcceleoGenerator.java:193)
at org.eclipse.acceleo.engine.service.AbstractAcceleoGenerator.doGenerate(AbstractAcceleoGenerator.java:158)
at org.melanee.core.melanee2metadepth.main.GenerateMetadepth.doGenerate(GenerateMetadepth.java:202)

How can I debug my problem to find out what is going wrong here?

Ralph
