Netbeans Linux and Windows Makefile-*.mk and Package-*.bash files in nbproject directories are automatically generated during compile. These files are continually updated, which can cause a long list of unnecessary files to add, commit, and push (or that are Untracked). This has been experienced for Linux and Windows C++ projects.

This file as documentation (which seems lacking) states is used for calling custom Maven goals from the IDE.
Ignoring this file was a source much confusion in few projects (mapping Run action to custom goals... etc etc)
Also this file does anything worth ignoring

Exclusion of `nbactions.xml` from `.gitgnore` should be discussed.
