Subject Re: mvn release:prepare does not update parent version
Date Tue, 23 Jul 2013 08:26:57 GMT
The example you mention updates the build artifacts only.

When you release code, you would of course assign a version number to the release, and you
can specify what snapshot version you want to use next. That makes the release consistent
with all of the tests. It's simple labeling what is being released.

Changing the version number of outside artifacts that you reference, on the other hand, is
a change in the definition and functionality of the system. There is no particular reason
to expect it to work, and more than if you decided to ask Maven to modify any other code in
your system.

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.

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.
