cordova build Command failed with exit code EACCES
This is a common PhoneGap problem.
Most of the time it has to do with permissions on the build
folder and script file.
Try using: chmod a+x
on them.
You should add permission to two files:
Go to Cordova root directory and run:
chmod a+x platforms/android/gradlew
chmod a+x platforms/android/cordova/build
For some reason build is not currently an executable file. To fix that, open the terminal and enter the following commands:
$ cd <your-project-directory>/platforms/android/cordova
$ chmod a+x build
