Description

I'm getting NPE when trying to do a release with provided parameters:

There was an additional changes in CheckoutProjectFromScm of maven-release-manager-2.0 that caused this:
MavenProject rootProject = ReleaseUtil.getRootProject( reactorProjects );

The reactorProjects is null when using provide paramters during release.
