How can set properties for determine last commit revision and author in maven?

Question

I want to get SCM url, last commit revision and last commit author so I can add them as metadata in my jar. I know I can get URL and revision but don't see a plugin which sets last commit author as a property.

• last commit revision ${buildnumber} as buildnumber-maven-plugin executs
• url: ${project.scm.url}
• author: ?????

Please let me know if you know how to get the author. At present i suspect I'll execute svn info ${project.scm.url} -r ${buildnumber} and then parse the output.

Thanks

Peter
