Re: [jbosstools-dev] Update manifest.mf file for nested dependencies against juno
It's possible it has to do with that it is optional, but this is still a
change for us as developers. it was optional in Indigo and the build
then still worked just fine. It is still optional in Juno, but now the
build craps out. So it's still something to pay attention to.

Upon closer inspection, in Indigo at least, org.eclipse.ui.views is
an _optional_ dependency of org.eclipse.ui.ide. Given that, do you think this problem may
be related to the fact that the imported dependency is optional?
Best,
