maven override project.version from command line

Question

I wonder if it is possible to override project.version/version variable in maven via command line?

The following doesn\'t work:

mvn deploy -Dversion=1.

In Maven 3.5+, if you put the following in your pom.xml

${revision}
...

    1.0.0-SNAPSHOT

it will use 1.0.0-SNAPSHOT by default, but you can override it on the command line:

mvn -Drevision=2.0.0-SNAPSHOT clean package

Apparently this only works if the placeholder property is called revision (you can also use changelist and sha1 placeholders in your version).
