JBIDE-13671 enable jgit timestamps using no BUILD_ALIAS of distinction between ci builds vs. local builds; also omit BUILD_NUMBER

Seems good to me.

This seems to work until we shift parent pom version to next one. That will trigger qualifier change everywhere, because of requirement for every module to update reverence to latest parent pom.

[nickboldt]

Why would it trigger qualifier change if none of the plugins or features are changed, only the root pom and the all-tests/pom.xml ?

[mickaelistria]

Nick is right. The default behavior (or at least the one we expect and that it's used by Eclipse Platform) looks at the last commit that affected the current module, so if only the version change in some parent pom. it's not cascaded to module.
However, I believe we should also configure this timestamp plugin to exclude even the current pom.xml, like http://git.eclipse.org/c/platform/eclipse.platform.releng.aggregator.git/tree/eclipse-platform-parent/pom.xml#n554

I looked at arquillian and saw latest commit, but didn't check what was actually changed and turned out it was version bump.

I am wrong - you are right 👍

Suggestion to exclude pom.xml captured in this PR: #225

If you guys feel we should do this, I'm all for it. @mickaelistria feel free to apply this tomorrow when you arrive at work, or we can discuss it further.

@nickboldt this commit has exact same label as the currently on master? Should I merge it anyway? Can you set a more accurate and precise commit message?
