This is validating the commit message which we made in local git repo. ( need to install & check this in git server side)

1. Place this file in the repo path .git\hooks\commit-msg
2. Try to add some changes to repo & commit without any message. Git will throw an error message “Commit message can NOT be empty.” which is exactly there in the above commit-msg file. (You can modify the message and try).

git commit -m “”

3. Try to commit with any message. You will get error message "Aborting commit. Your commit message is missing either a JIRA Issue ('WAP-1111') or 'Merge'"

git commit -m “updating changes”

4. Try to commit with below message. Commit success. As per the grep/regular expression, this time commit is success.

git commit -m “updating changes WAP-123”

If this is useful, you can update the script as per your requirement.
