I get the following error output while running the Maven release plugin prepare step i.e. mvn release:prepare --batch-mode -DreleaseVersion=1.1.2 -DdevelopmentVersion=1.2.0-SNAPSHOT -Dtag=v1.1.2 -X from an Atlassian Bamboo plan. However doing the same in the command line works fine. The full error stack is below.
Any ideas how can this be solved?

and this is very weird why is the local development clone output so different from the Bamboo one?
I ran into the same error on Jenkins in combination with maven release plugin, we fixed it by going to Additional behaviours, Check out to specific local branch and enter 'master'
I realise this is not a solution but it might give you some direction in where to look.
For Jenkins and GIT add the additional behaviour check out to specific local branch and use the Workspace Cleanup Plugin to clean your workspace to the beginning of your CI job.
The problem in Atlassian Bamboo was solved by un-checking the default setting Use shallow clones with description Fetches the shallowest commit history possible. Do not use if your build depends on full repository history. This checkbox is located under Plan Configuration -> Repositories tab -> Git -> Advanced options
After this all the releases work fine.
Unchecking the Use shallow clones was not sufficient in my case (I'm using Bamboo 5.7.2). I needed to also enable Force Clean Build in the Source Code Checkout task. Enabling the Use shallow clones would work for the next execution of the job, but all subsequent execution would result in the same error.
I have seen this problem under Bamboo used with Maven Release plug-in. I've fixed it by enabling the option 'Force Clean Build' in the 'Source Checkout' task. Bamboo says this might make the build slower, but it works and I didn't seen any significant time increase.
what worked for me was to call "git checkout -f master" before calling "mvn release"
I am using a Jenkins Team Project with a Multibranch Project Setup.
I previously used checkout scm command.
Now I am using the following code:
checkout([
$class: 'GitSCM',
branches: scm.branches,
extensions: scm.extensions + [[$class: 'CleanCheckout'], [$class: 'LocalBranch', localBranch: 'new']],
userRemoteConfigs: scm.userRemoteConfigs
])
For us the issue was with maven version specified in the pom file. Corrected the maven version specified in the pom file in accordance with the one in bamboo fixed the issue
