Update to version 3.6.1 and rename
I looked at updating the port to the latest version: the fetch path is incorrect unless one sets the name to commons-math (without the 3) so I also took the chance to rename the port to apache- instead of jakarta-.
Please remember to move the port accordingly.
I also had to change JARFILE, not sure how to make the change cleaner to drop the minor number with a regex.
