Adding groupid to the maven release plugin's scm tag

["Nau, Mike" <Mi...@intuit.com>]

Hi All,

I'm looking into adding the artifact groupid to the scm tag created by the maven release plugin during the release:prepare goal. I've gotten pretty close with the following configuration:

<groupId>com.foo</groupId>
<artifactId>bar </artifactId>
<version>1.0.0-SNAPSHOT</version>

<configuration>
  <tag>${pom.groupId}:${pom.artifactId}-${pom.version}</tag>
</configuration>

The only problem with this is ${pom.version} is resolving to the next snapshot version. So for example if I run the release:prepare and the current version of the pom is 1.0.0-SNAPSHOT the tag is applied to our scm system as com.foo:bar-1.0.1-SNAPSHOT, instead of com.foo:bar-1.0.0. 

I tried using ${releaseVersion} instead of ${pom.version} based on the details here: http://maven.apache.org/plugins/maven-release-plugin/prepare-mojo.html#releaseVersion. But that property is not valid - it dereferences to null in this case. 

I want to include the groupId in the tag to avoid and potential naming conflicts with other projects. Using just the artifactid and the version aren't enough to ensure a project's scm tag won't collide with another projects scm tag. 

We are using Perforce as our scm provider so period's in the tag\label names are not a problem. We are running the release goals in batch mode. 

Any ideas?

Thanks,
-Mike
