Recently having switched source code repository for a project to GitHub from SourceForge I need to update the maven release process to match. I followed this link for configuring the "scm" section of the pom. The GitHub repository is shown here. Everything else is as it was when using SVN (for publishing to https://docs.sonatype.org/display/Repository/Sonatype+OSS+Maven+Repository+Usage+Guide#SonatypeOSSMavenRepositoryUsageGuide-4.MavenRepositories). So then I invoke

mvn clean release:clean release:prepare release:perform

and the output is as follows

Now a connection of "scm:git:git://github.com/{organization}/{project}.git" is what all examples I've seen for maven-release-plugin so would appreciate any insight in why it doesn't work here, or what I could look at to find out why. I can do a git push to the same URL using the user I'm logged on here as (GitHub has the SSH key).

I tried swapping the scm connection/developerConnection over to https and then get username/password prompted and it then hangs (it updates the GitHub repo with the version without SNAPSHOT) but that's all.

Actually the problem was more of believing web links of how you should configure your SCM section, so I post the answer here in case anyone else hits this message. The connection/developerConnection should be of the form

scm:git:[email protected]:{organization}/{project}.git
