gradlew: Permission Denied

I am attempting to run gradlew from my command line, but am constantly facing the following error. ``` Brendas-MacBook-Pro:appx_android brendalogy$ ./gradlew compileDebug --stacktrace -bash: ./gradlew: Permission denied ``` I am already running this command from my project directory. Need to run this command as I am facing the same (nondescriptive) error on Android Studio 0.2.x as encountered here: Android studio and gradle build error Am I doing something wrong and how do I get around this?
