Hello, I am using Libgx in conjunction with MOE. I recently upgraded my project to Java 8, I subsequently added several lambda functions throughout our my code. It’s my understanding that retrolambda is built into the gradel moe plugin so I didnt think it would be a problem but when I attempt to build I keep getting a
java.lang.NoClassDefFoundError: ... $$Lambda$...
More specifically:

Please point me in the right direction if this topic has already been discussed as I haven’t found anyone else with this same problem. I am probably missing a fundamental step due to the lack of discussion on this topic. I don’t really know if this is a problem with libgdx, progaurd or moe so here’s here are all facts that might be helpful:
My Gradle
gdxVersion = '1.9.6'
classpath 'org.multi-os-engine:moe-gradle:1.+'
compile "com.badlogicgames.gdx:gdx-backend-moe:1.9.6
(changing either of the gdxVersion or gdx-backend-moe to 1.9.9 has no effect)
My Appended Additions To The Progaurd Config File
