Re: [tycho-user] Enforcing package version constraints

[Brian de Alwis <briandealwis@xxxxxxxxx>]

Is there a way for the TP to exclude an artifact?

Our TP includes the version of m2eclipse that was contributed to the Mars release train, which requires com.google.guava [14.0.1,16.0.0).  Although we could include the most recent release of m2e in our TP, I'm fairly sure that our users still using Mars will be using the m2e contributed on the release train.  Maintaining a testing TP and a development TP doesn't sound like much fun, especially since we're maintaining a TP for each release train already.

PDE's quick-fixes for adding an import-package helpfully provides a `version` constraint where possible, but it uses the lowest version available in the target platform.  So when developing against a TP for Eclipse Mars, where m2eclipse pulls in Guava 15, all com.google.common.* packages are added with version "15.0.0".  Since we use Guava 20, we have to remember to change any such version constraints be "[20,21)".  Such is life.
