Subject RE: mvn release:prepare does not update parent version
Date Tue, 23 Jul 2013 08:40:52 GMT
So this is a known bug or is it just a configuration error that I did?

I have to specify all versions of each module of my reactor? Or it can take
the basic version-DreleaseVersion for each module?

Objet : AW: mvn release:prepare does not update parent version


is there actually a reason why only the artifacts in the build are updated?

I would agree that without providing versions for artifacts manually, this
could cause problems, but when using the feature described here:
It is possible to provide separate versions for every module. 

In my release I provided release and development versions for all modules
(also ones not in the reactor), but the release:prepare simply skipped those
not in the build.
I had to create a patched version for this, but it was a pretty unsatisfying
solution. If the plugin would for example update all those versions in the
reactor plus all those I manually provided a version for, might solve
Markus' problems.

I don't think the language says that at all. I ran a quick build and I'm not
seeing where it says it will update every single SNAPSHOT version referenced
in the POM. Can you please paste it?

And it should not. It will rewrite the versions for the artifacts in its
build plan, and the parent is not part of the build plan in this way. It
would be horrifying, frankly, if running a release in a project would go
update the parent project also.

I don't think it should obviously do that. Perhaps you actually intended to
run the release from the parent, if that is true, then you should do it from
there. Not from within some submodule.

Run the release from the proper location. Or if the parent really does not
have a submodule of the project you're errantly trying to run the release
from right now, then you should release it (parent) first and then make the
updates in the unlinked child projects to the latest release number. The
m-versions-p is quite adept at automating this process.
