release branch not working as expected

[Matt Milliss <ma...@gmail.com>]

I'm having trouble getting the maven-release-plugin to work in a 
non-interactive way. I'm trying to create a branch with the version 
09.20.01-SNAPSHOT from the trunk version 09.20.00-SNAPSHOT.
I'm using the following command to branch manually,

mvn release:branch -DbranchName=09.20.00_BRANCH 
-DupdateBranchVersions=true -DupdateWorkingCopyVersions=false

and when prompted for the branch version I enter 09.20.01-SNAPSHOT, this 
works as expected and the branch is created with the version 
09.20.01-SNAPSHOT.

Now I thought the following command would have the same effect but the 
branch is created with the 09.20.00-SNAPSHOT not the 09.20.01-SNAPSHOT 
version specified in the command

mvn release:branch -DbranchName=09.20.00_BRANCH 
-DupdateBranchVersions=true -DupdateWorkingCopyVersions=false 
-Dproject.rel.net.moneyswitch:extranet=09.20.01-SNAPSHOT --batch-mode

Is this a bug in the 2.0-beta-9 of the release plugin that I'm using or 
am I doing something wrong? Any help would be appreciated.

I am using 2.0-beta-9 of the release plugin and my environment is
Apache Maven 2.1.0 (r755702; 2009-03-19 06:10:27+1100)
Java version: 1.6.0_10
Java home: /usr/java/jdk1.6.0_10/jre
Default locale: en_AU, platform encoding: UTF-8
OS name: "linux" version: "2.6.30.8-64.fc11.x86_64" arch: "amd64" 
Family: "unix"
