Sometimes, we need to get a Jira key for later usage.
For example, we can need it to do some release notes or other things.
This is the regex that I use with an example of usage.
Regex
You need to replace PRJ by your project:
'((PRJ-)+([0-9]*)?)'
Example of usage
Extract the Jira key from all commits between 2 tags:
git log rs420..rs422 --pretty=oneline | grep -oE '((PRJ-)+([0-9]*)?)' | sort -u
This permits us to obtain a clear list like:
PRJ-4056
PRJ-4057
PRJ-4105
PRJ-4189
The job is done, very easily and can be used for a lot of things like interacting with Jira API if needed.
