release:prepare does not check for existing tag and updates the tag in a wrong
way
----------------------------------------------------------------------------------
Key: MRELEASE-572
URL: http://jira.codehaus.org/browse/MRELEASE-572
Project: Maven 2.x Release Plugin
Issue Type: Bug
Affects Versions: 2.0-beta-9
Reporter: Jens Beyer
If the targetted release tag already exists (like accidentally re-releasing a
version), release:prepare does not complain about already existing tag, and
updates the tag in a wrong way.
Example: I call mvn release:prepare on my-project-1.0.0-SNAPSHOT. The tag
my-project-1.0.0 already exists.
Expected result: mvn fails with the error "version tag my-project-1.0.0 already
exists in SCM"
Current result: my-project-1.0.0 tag (!) is updated, with a new subdirectory
called 'my-project', below that is the expected result of the re-release; the
old data of the tag is still present.
I'd rather never update a tag (hence I'd like it to fail). That's why I tagged
it.
