Description

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
