version is duplicate of parent version

[elharo]

What should we do about all the version is duplicate of parent version errors in eclipse? In particular, if we remove duplicate versions will this make it easier or harder to upgrade the version in the future?

Or maybe we should deliberately decouple the versions so parent and child versions are in fact different.

I think it's best to disable that error: Preferences > Maven > Error/Warnings > "version" duplicate of parent version → Ignore.

Some of this disappears if we move to a pomless build, where the Tycho only needs poms for specifying additional dependencies or configuration information. I started looking into doing this a while back, but … I stopped as I thought pomless was in Tycho 0.25.0 which required Java 8, and wasn't sure how to ensure our tests ran with Java7. But now I see it was introduced in 0.24.0…

If we can make pomless work, great; but one way or another I do want to reduce the friction of changing our version numbers.
