Issue with proguardFile, null returned: 1
android, ant, proguard
Solution
In my case, there also was an error report earlier in the logs, it was just difficult to find. As I understand, any kind of error would lead to that message.
So the crazy message `null returned: 1` actually means please read the above logs.
Problem
