Re: [p2-dev] updating tycho version to 0.13.0 for p2 build

Hello all,
The workaround Brian described (jars.extra.classpath) works just fine
https://bugs.eclipse.org/bugs/attachment.cgi?id=204623&action=diff

so... no biggie after all, I guess :-)
Anthony

Well, even though I trust the author of the  sentence you quoted :) It seems that despite all our efforts as a community to consider all the corner cases from the provisioning angle, we simply forgot about the compile time aspect for Tycho (interestingly enough the driver for this change was a Tycho committer :p)

In fact I would go even further and qualify this of bug in tycho since this means that you can't really use optional dependencies without additional burden.
