I try to build my Ionic project with JBoss Developer Studio. But constantly I get the following problem. I can't build the project on the "Android device" and on the "Android emulator".

Error:

BUILD FAILED

Cause: The name is undefined.
Action: Check the spelling.
Action: Check that any custom tasks/types have been declared.
Action: Check that any <presetdef>/<macrodef> declarations have taken place.
