Re: [tycho-user] how does the tycho compiler for test code find all the dependencies?

The best would be to upgrade your project to 2.5.0-SNAPSHOT [1]

This generally helps us to discover regressions early and verify bug-fixes and new features.

but for now this will just not work with tycho 2.4 right?

so for this project i just need to fallback to 2.3 until 2.5 is out with a fix that really looks at the pom (test) dependencies for compiling and running tests.

    I fully agree with you that this should 'just work' but until now it
    was
       doubt that this is useful or even a valid use-case and I was a bit
    lost to argue fore more support in that area.

    Because of this its good to know that there are other people having
    such
    'strange' setup/uses and I'll try to provide a fix for your case ASAP...
