release:branch in mercurial provider updates the version in the new branch
--------------------------------------------------------------------------
Key: SCM-643
URL: https://jira.codehaus.org/browse/SCM-643
Project: Maven SCM
Issue Type: Bug
Components: maven-scm-provider-mercurial (hg)
Affects Versions: 1.5, 1.6
Reporter: Jared Bunting
Attachments: hg-scm-branch-fix.patch
When running release:branch with a mercurial repository, and having all
properties set to defaults, I would expect the current version to be carried
over to the new branch, and the new "developmentVersion" to be set on the
original branch. This is the behavior that I have always seen in the
subversion provider (which is the only other one that I really have experience
with), and what I believe the documentation states. However, that is not the
behavior that I am seeing. I see the branch created, then the new version set
on the branch.
I believe the issue is that HgBranchCommand not only creates a new branch, but
updates the working copy to the new branch. This seems to be counter to the
behavior expected by maven-release-plugin, differs from the behavior in the
subversion provider, and also seems to not be the behavior described in the
ScmProvider interface.
Since this "updating to the new branch" behavior is inherent to mercurial, I've
written a patch that saves the original branch name prior to branching, and
after branching is complete updates to the original branch.
