问题
Since I have Java 1.8 in my local setup and need 1.7 for Grails, I installed jEnv.
When I run grails command via jenv on my Grails project directory, I get this error -
sandeepan.nath$ jenv exec grails
objc[31865]: Class JavaLaunchHelper is implemented in both /Users/sandeepan.nath/.jenv/versions/1.7.0.80/bin/java (0x1003b74c0) and /Library/Java/JavaVirtualMachines/jdk1.7.0_80.jdk/Contents/Home/jre/lib/libinstrument.dylib (0x1004724e0). One of the two will be used. Which one is undefined.

This exception does not clearly say what is the issue. I am able to create a fresh grails application though. No issue with that.
