I at attempting to perform the set up of a Forge development environment on Mac OSX (Mavericks) and I consistently get the following error: * What went wrong: Execution failed for task ':mergeJars'. > java.util.zip.ZipException: error in opening zip file I have tried with both the latest version of Forge (10.12.0.1047) and the recommended version (10.12.0.1024). In both cases I receive the zip file error. I did notice that the folder referenced in the logs at /Users/scott/.gradle/caches/minecraft/net/minecraft/minecraft_merged/1.7.2/ doesn't contain the minecraft_merged-1.7.2.jar, but I'm not sure if that's really the issue. Anyone have an idea? Build log:
