As long as we don't have a fully compliant parser, it is best to skip this for file:// URLs.
Jenkins fails with:
org.apache.maven.wagon.TransferFailedException: Error getting file from SCM
Caused by: org.apache.maven.scm.ScmException:
command failed: Cloning into 'checkout-org.apache.maven.wagon.providers.scm.UserSafeGitExeScmProvider'...
fatal: '/m/wagon-providers/wagon-scm/target/test-classes/test-repo-git-test/' does not appear to be a git repository
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
This is due to bad parsing of the URL containing an at sign as path component.
