Subject [jira] [Commented] (MNG-5576) Allow continuous delivery friendly versions
Date Mon, 29 Aug 2016 07:18:21 GMT


Vincent Massol commented on MNG-5576:

Hi. Why not support any property in <parent>/<version> elements in POM or if that's
not possible, why not support ${project.version}?

I'd like to be able to to write:


And in the top level POM have:

>                 URL:
>             Project: Maven
>          Issue Type: Improvement

>            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.
