|Re: [tycho-user] testing compilation of a generated plugin project (with swtbot and tycho)|
I had the same issue with GMF Tooling, it applies to any test or code that generates bundles inside Eclipse.
The default target platform in Eclipse looks for bundles in plugins/ folder, which is not accurate with Tycho since the bundles are resolved from Maven repository.
See https://bugs.eclipse.org/bugs/show_bug.cgi?id=343152 and http://dev.eclipse.org/mhonarc/lists/tycho-user/msg00059.html and more important, the issue in PDE: https://bugs.eclipse.org/bugs/show_bug.cgi?id=343156
And a workaround here: http://dev.eclipse.org/viewcvs/viewvc.cgi/org.eclipse.gmp/org.eclipse.gmf.tooling/tests/org.eclipse.gmf.tests/src/org/eclipse/gmf/tests/AllTests.java?root=Modeling_Project&r1=1.104&r2=1.105
