Maven Release-plugin "tag already exists" for nonexistant tag

git maven bamboo bitbucket-server svn2git

My setup: git-repository on an Atlassian Stash-server and Atlassian Bamboo. I'm using Maven 3.1.1 with the release-plugin 2.3.2. The plan in Bamboo looks like this:

  1. Check out from git-repository
  2. perform a clean install
  3. perform release:prepare and release:perform with ignoreSnapshots=true and resume=false

Everything up to the last step works fine, but Maven states, that it can't tag the release, because the tag already exists. Here is the log:

build   26-Nov-2013 10:36:37    [ERROR] Failed to execute goal org.apache.maven.plugins:maven-release-plugin:2.3.2:prepare (default-cli) on project [PROJECT-NAME]: Unable to tag SCM
build   26-Nov-2013 10:36:37    [ERROR] Provider message:
build   26-Nov-2013 10:36:37    [ERROR] The git-tag command failed.
build   26-Nov-2013 10:36:37    [ERROR] Command output:
build   26-Nov-2013 10:36:37    [ERROR] fatal: tag '[PROJECT-NAME]-6.2.2' already exists

Well, obviously the tag already exists, no big deal. However, this is what git tag looks like for my repository: 

bash:~/git/repositories/PROJECT-NAME$ git tag
[PROJECT-NAME]-5.2.5
[PROJECT-NAME]-5.3.0
[PROJECT-NAME]-5.3.1
[PROJECT-NAME]-5.4.0
[PROJECT-NAME]-5.5.0
[PROJECT-NAME]-5.5.1
[PROJECT-NAME]-5.5.2
[PROJECT-NAME]-5.5.3
[PROJECT-NAME]-5.5.4
[PROJECT-NAME]-5.6.0
[PROJECT-NAME]-5.6.1
[PROJECT-NAME]-5.6.2
[PROJECT-NAME]-5.6.3
[PROJECT-NAME]-5.6.4
[PROJECT-NAME]-5.6.5
[PROJECT-NAME]-5.6.6
[PROJECT-NAME]-6.0.0
[PROJECT-NAME]-6.0.1
[PROJECT-NAME]-6.0.2
[PROJECT-NAME]-6.1.0
[PROJECT-NAME]-6.1.1
[PROJECT-NAME]-6.1.2
[PROJECT-NAME]-6.2.0
[PROJECT-NAME]-6.2.1

The git-repository is cloned via svn2git from an svn-repository. I've tried multiple times reimporting the repository and deleting and re-cloning it on the stash-server. Yet the tag 6.2.2 seems to exist somewhere in the depths for Maven. What's going on here?

Update: I just tried removing ALL tags from the repository. Same result. Changing the version from 6.2.2 to 6.2.3 showed positive results.

Another update: It seems to have something to do with the name of the repository. Creating a new repository with the same name but adding -2 at the end helped.

mvn release:clean before release:prepare is what worked for me
