How to create a branch from an SVN tag with Maven?

Question

Suppose I noted the release version of our project under $SVNROOT/project/tags/1.0. Suppose now that I need to create a branch from this tag, mark it as SNAPSHOTand update the configuration scm.

I tried with the goal release:preparein this way:

$ svn co $SVNROOT/project/tags/1.0 project-1.0
$ cd project-1.0
$ mvn release:branch -DbranchName=project-1.0.X -DupdateBranchVersions=true -DupdateWorkingCopyVersions=false

But this fails, with an error message warning me that I do not have the right to pass to the path $SVNROOT/project/tags/1.0 project-1.0(which is absolutely true --- we do not allow commits to tags).

What am I doing wrong here, and why did Maven try to commit something to the tag?

Update

Just to clarify: I run this from the directory in which I checked the tag. The exact error I get is the following:

[INFO] Executing: /bin/sh -c cd xxx && svn --non-interactive commit --file /tmp/maven-scm-28755080.commit --targets /tmp/maven-scm-535803351230252749-targets

Answer 4

The actual problem is that the target release:branchcaptures tags that are unconscionable error . There is no workaround. Your prefix hook probably doesn't work because it is designed - possibly correctly - to prevent crashes inside the tag directory.
