versionnumber-plugin evaluates the environment variables before the envinject-plugin injects them, if the envinject-plugin is configured to inject them from a source file checked out from SCM.

The versionnumber-plugin has a "Version Number Format String" field which can take environment variables as the input. Trying to inject the variable, results in a blank evaluation of the variable, because it's instantiated from the SCM sourced file after the versionnumber-plugin.

It would be nice if to alter the order in which these plugins are run so they can work together.
