commitVersionFileOnly issue in GitAdapter

[mprinci2]

I'm trying to run this plugin in a multi-project multi-version setting using the commitVersionFileOnly property set to true. I run the release task from the top-level project, and when the task updates each subproject to its new release version, the correct subproject version property file is updated (using project.file(extension.versionPropertyFile)). However, it is the top-level version property file that ends up being added to the Git commit, which is incorrect.

On line 126 in GitAdapter.groovy, the code should change from command << extension.versionPropertyFile to command << project.file(extension.versionPropertyFile) so the correct version property file is added to the Git commit.
