Where can I check Ionic's compiler error output?

I'm using Ionic and this is the message:

BUILD FAILED C:\adt\sdk\tools\ant\build.xml:720: The following error occurred while executing this line: C:\adt\sdk\tools\ant\build.xml:734: Compile failed; see the compiler error output for details.

Total time: 5 seconds

C:\wamp\www\external\projectx\dirx\platforms\android\cordova\node_modules\q\q.js:126

Where can I see the log details? I've tried googling a bunch of things like "ionic log path" etc but nothing comes up. I saw something else that said run it with a -c argument but the output is the same.

Make sure you update your sdk, sometimes error occur when trying to build android incompatible API to your cordova version or ionic.
