I have a framework of my own that I use for in-class tasks (school class, not Java class), and I made it into a .jar file so that whenever I make changes to the framework, I can just drag and drop it into Android Studio. Everything worked well for the past 5 or so class tasks, and now all of a sudden I'm getting a preDexDebug failed error when parsing my .jar after clicking run. I tested this on a blank project. The project has a total of 2 .jars: Gson, and my own jar. It prints out preDexDebug failed right after I pull in my own .jar... I've wrestled with this for two infuriating hours, and I don't know what I can do to fix this at all...
I've tried rebuilding, cleaning, checking gradle.build for duplicates, replicating the project multiple times, and also compiling and copying the .jar multiple times as well.
Ubuntu x64 with 64 bit Oracle JDK 1.8.0_31. Using Java bundled with the JDK
Android Studio output:

bad magicerror on here. I looked into it, and it seems that the Android SDK only officially supports Java 7, so the error makes sense now. I'm going to try compiling on my laptop for the moment – Alex
