Mickael Istria commented on JBIDE-13671:
----------------------------------------

[~maxandersen] You can see it here: https://github.com/mickaelistria/jbosstools-freemarker/tree/JBIDE-13671 It requires to have installed Git experimental parent pom. Then populate a repo with what you want as baseline and set the baseline in pom.xml.

It's possible to exclude pom from watched resources for the Git timestamp provider.
Ideally, we would like to achieve a similar behaviour that would ignore qualifiers, so we won't have to brainstorm about what's the best qualifier to implement this, Tycho would take an already built bundle if the content are the same, except qualifier.
