In general, the artifacts that are produced by calls to the Maven Wagon should be idempotent. In this particular case when resolving transitive git dependencies the checksum call was made twice. The second time it failed because the checksum file already existed and the regex confused it for the file to checksum (eg: pom or jar). This fixes the regex for these cases.
