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

$M2_HOMEis used sometimes, for example, to install Takari Extensions for Apache Maven

One way to find $M2_HOME value is to search for mvn:

sudo find / -name "mvn" 2>/dev/null

And, probably it will be: /opt/maven/
