Using some code I worked on in the past I have wrote a java class that does the job. Disclaimer, I'm not an advanced programmer, so this code may have some bugs and can probably be optimized.
PostReceiveRepositoryHook Class creates post-receive hook that triggers script after the code update is merged to branch. It works both with updates pushed via git push and merged pull requests.
- Create Stash plugin with post receive hook module and use the class below
- Set script path in the hook configuration. If Stash on Windows make sure to use double backslash
- Plugin will pass three arguments to the script: Stash Project Name, Repo Name and the branch that was just updated.
