Run from a heap running Proguard in Android Gradle build

When I try to run Proguard on my local computer from my Gradle assembly, I get a Java heap heap error. In particular:

:<app_name>:proguardRelease FAILED FAILURE: Build failed with an exception. * What went wrong: Execution failed for task ':<app_name>:proguardRelease'. > Java heap space

I tried setting my GRADLE_OPTS = -Xmx2048m, but I'm still getting an error in the heap area.

Any suggestions?

Here is the end of my log output:

Have you also exported an environment variable (on Linux and BSD)?

 export GRADLE_OPTS=-Xmx2048m
+14
source share

If someone encounters this problem in AndroidStudio, without Gradle, the solution is to add some memory to proguard:

 Android Studio >> Preferences >> Compilers >> Android Compiler >> Proguard Options = -Xmx2048m
+3
source share
