Unable to run mvn clean install on macOS Sierra 10.12.6

I am using maven-3.1.1 along with eclipse neon for RCP and jdk-7. I am running into the following issue - Error with Maven command: mvn clean install Problem running the Maven command because the process is 'null'. Is Maven installed correctly and located on your PATH? Running mvn version on terminal gives: mvn -version Apache Maven 3.1.1 (0728685237757ffbf44136acec0402957f723d9a; 2013-09-17 10:22:22-0500) Maven home: /Users/lnoob/apache-maven-3.1.1 Java version: 1.8.0_131, vendor: Oracle Corporation Java home: /Library/Java/JavaVirtualMachines/jdk1.8.0_131.jdk/Contents/Home/jre Default locale: en_US, platform encoding: UTF-8 OS name: "mac os x", version: "10.12.6", arch: "x86_64", family: "mac" echoing the PATH gives: /Users/lnoob/.rvm/gems/ruby-2.3.1/bin:/Users/lnoob/.rvm/gems/ruby-2.3.1@global/bin:/Users/lnoob/.rvm/rubies/ruby-2.3.1/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Applications/Wireshark.app/Contents/MacOS:/Users/lnoob/.rvm/bin:/Users/lnoob/apache-maven-3.1.1/bin Any thoughts on what is going on?
