Mirko Friedenhagen commented on MNG-5576:
-----------------------------------------
I "abuse" the preparationGoals parameter of release:prepare and get away we a
one shot invocation, see
https://github.com/1and1/foss-parent/blob/master/release for an example.
> Allow continuous delivery friendly versions
> -------------------------------------------
>
> Key: MNG-5576
> URL: https://jira.codehaus.org/browse/MNG-5576
> Project: Maven 2 & 3
> Issue Type: Improvement
> Affects Versions: 3.1.1
> Reporter: Jason van Zyl
> Fix For: 3.2.1
>
>
> Currently warnings will be emitted when there are expressions in versions, a
> few exceptions should be deemed valid to make continuous delivery easier. The
> use case is to allow easy versioning of an entire multi-module build that can
> take a version from an external source like SCM. These are the types of
> exceptions that will be allowed:
> 1.0.0.$\{changelist}
> 1.0.0.$\{revision}
> 1.0.0.$\{sha1}
> When a whole build is versioned like this we can avoid churning the POMs in
> the SCM which makes it a lot easier to see the actual changes in the project.
> Not a complete solution for continuous delivery but is a step in the right
> direction and doesn't interfere with currently behavior as it is currently
> allowed, just warned against.
