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:

{code}
...
  <parent>
    <groupId>org.xwiki.platform</groupId>
    <artifactId>xwiki-platform-activeinstalls</artifactId>
    <version>${project.version}</version>
  </parent>
...
{code}

And in the top level POM have:

{code}
...
  <version>1.0-SNAPSHOT</version>
...
{code}

Thanks

> 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.
