I struggled with the same issue  and the following worked for me   Step 1  Check your JAVA HOME setting  It may look something like   JAVA HOME   usr libexec java home    Step 2  Update JAVA HOME like so     vim  bash profile   export JAVA HOME    usr libexec java home     source  bash profile   Step 3  In a new shell  check that the Maven command is now working properly     mvn -version   If this fixed the problem  you should get back a response like   Apache Maven 3 0 3  r1075438  2011-03-01 01 31 09 0800  Maven home   usr share maven Java version  1 7 0 05  vendor  Oracle Corporation Java home   Library Java JavaVirtualMachines 1 7 0 jdk Contents Home jre Default locale  en US  platform encoding  UTF-8 OS name   mac os x   version   10 8 2   arch   x86 64   family   mac

It seems that Maven doesn t like the JAVA HOME variable to have more than one value  In my case  the error was due to the presence of the additional path C  Program Files Java jax-rs  the whole path was C  Program Files Java jdk1 8 0 20 C  Program Files Java jax-rs    So I deleted the JAVA HOME variable and re-created it again with the single value C  Program Files Java jdk1 8 0 20
