Robert Scholte commented on MRELEASE-431:
-----------------------------------------
[~rombert], what's still missing is how this is set from the Maven Plugin and
how the chosen implementation is selected.
{code}
/**
* @plexus.requirement
role="org.apache.maven.shared.release.phase.VersionPolicyManager"
*/
private Map<String, VersionPolicyManager> managers;
{code}
With this piece of code, Plexus will collect all available implementations of
{{org.apache.maven.shared.release.phase.VersionPolicyManager}} on the classpath
and will use its hint as the key for this map.
By passing the role-hint of the Manager, you can pick up the preferred
implementation.
> Configuration of policy for calculating next (release) version

> Key: MRELEASE-431
> URL: https://jira.codehaus.org/browse/MRELEASE-431
> Project: Maven Release Plugin
> Issue Type: New Feature
> Components: prepare
> Affects Versions: 2.0-beta-8
> Reporter: Carsten Ziegeler
> Assignee: Robert Scholte
> Fix For: 2.5

> Currently, when preparing the release, the version to release is always the
> next version which usually is the current version without the snapshot
> extension.
> There are quiet a lot projects (Apache Felix, Sling and others) following an
> even release numbering policy. So while the current development version is
> odd (like 1.2.3-SNAPSHOT), the next released version will be 1.2.4.
> It would be nice if this could be made configuration through some
> configuration property like
> <versionPolicy>next-even</versionPolicy> (with possible values being: next
> (default, as-is), next-even, next-odd
> I briefly scanned through the code and it seems that adding support for this
> requires changes in both, the release-manager and the release-plugin.
> If this feature gets accepted and if someone could give me some minor hints
> how/where to add this I could come up with a patch.
