[tycho-dev] Issues with ITs



I submitted a patch ( and made the mistake to not run the it tests locally before pushing – SORRY for that.
Now some tests are failing (locally and on hudon) and I do not know why. I did not introduced new dependency in any pom or manifest file but get this error:

What I did is i created a new class within tycho-core which is using the org.codehaus.plexus.interpolation.Interpolator but as I said, I did not had to add a new dependency to the pom.xml file. It looks that “only” the tests are failing. If I run tycho with different plugin/feature/product locally, everything works fine.


Does anyone have a hint for me?
