The people who write the software you are trying to build have decreed that you need to use a recent version of Maven in order to build correctly. They have defined an enforcer rule to enforce their minimum maven version requirement. The enforcer rule has kicked in and failed the build early because you are using maven version 2.2.1 and the allowed range is [3.0.2,)
Maven has a version range syntax. briefly [x] means only version x and no other version [x,y] means any version >=x and <=y [x,y) means any version >=x and <y (x,y] means any version >x and <=y (x,y) means any version >x and <y (,x] means any version <=x [x,) means any version >=x (,x) means any version <x (x,) means any version >x HTH On 25 October 2013 07:46, [email protected] < [email protected]> wrote: > Hi, > i am very new to maven.
