MAVEN_HOME, MVN_HOME or M2_HOME

Question

What\'s the correct Maven environment variable name: MAVEN_HOME, MVN_HOME or M2_HOME?

I\'ve found some details about M

Answer 1

I stumbled over this as chocolatey sets M2_HOME. I wanted to locate settings.xml.

The current way for settings.xml is to go to %USERPROFILE%. There, a directory .m2 is contained, where one finds settings.xml.

Never use M2_HOME. It is unsupported since Apache Maven 3.5.0.

Details:

Based on problems in using M2_HOME related to different Maven versions installed and to simplify things, the usage of M2_HOME has been removed and is not supported any more MNG-5823, MNG-5836, MNG-5607.

Important change for windows users: The usage of %HOME% has been replaced with %USERPROFILE% MNG-6001
