Hi,
I have a DSL that uses Xbase with a generator that outputs Java classes.
The DSL may reference existing Java classes. To test the generator I
have written Junit tests that test the generated classes. E.g. from DSL
file A.dsl I generate A.java which is tested with ATest.java.
I'm now trying to get maven to execute these tests. The idea is to first
run the mwe generator workflow (using the fornax maven plugin), and then
compile the generated Java and the test classes, before executing the
tests. This works for self-contained DSL files, but not when they
reference java files.
In my current setup, the referenced java files are compiled in the
normal compile phase, then the mwe workflow is executed in the
generate-test-sources phase. These two steps seems to be triggered
correctly, but the compiled files from the compile phase end up in the
target directory, which apparently isn't visible to (on the classpath
of) the DSL when run from the mwe workflow.
Any suggestions?

For the record, here's the setup that worked:
my.dsl.tests.util contains sources that the DSL models refers to. This
project is an ordinary plugin project registered in the pom.xml as an
eclipse-plugin project
my.dsl.tests contains the DSL models that refer to types in
my.dsl.tests.util. In the pom it is registered as an
eclipse-test-plugin. The fornax maven plugin runs the mwe2 workflow
during the generate-test-sources phase before the normal operation of
the Tycho plugin kicks off the tests.
