Date Tue, 03 Dec 2013 15:23:45 GMT


Idan Bidani commented on MNG-5533:

M3_HOME name is not good because it will require the same discussion on maven 4(if there will
If any change should take place it should be MVN_HOME like Michael suggests. The version should
not be part of the var name

> Maven 3 uses the M2 environment variable. Surely it would be more reasonable to update
this to M3 to allow sensible migration.  e.g
> M2=C:\Program Files\Apache Software Foundation\apache-maven-2.2.1\bin
> M2_HOME=C:\Program Files\Apache Software Foundation\apache-maven-2.2.1
> M3=C:\Program Files\Apache Software Foundation\apache-maven-3.1.1\bin
> M3_HOME=C:\Program Files\Apache Software Foundation\apache-maven-3.1.1
> MAVEN=%M2%  or MAVEN=%M3%
