I am trying to build a contact sensor, I have gotten everything to work so far. But, I keep having a warning and it keeps creating way too many targets. The warning states "Warning at the command line "--args":1:19: Build argument has no effect." I do not know what I am missing. I have looked through and compared the files to the lock app (leaving off the lock app parts). The build and args files seem to be right. But, i cant figure out where I am wrong. Is there any fixes that I can try?
