[MNG-6438] Continuous Delivery friendly versions do not work on root pom's parent

**[Konrad Windszus](https://issues.apache.org/jira/secure/ViewProfile.jspa?name=kwin)** opened **[MNG-6438](https://issues.apache.org/jira/browse/MNG-6438?redirect=false)** and commented

If I use either `${revision`},`${sha1`}, or `${changelist`} in the root pom's parent version it simply does not work, even when the project is invoked via
`mvn package -Drevision=1.0` and the according parent is available in version `1.0` in my Maven repo.
Instead I get the following error

```
mvn package -Dsha1=1.0

The following minimum pom can be used for testing
