[1.7.10] Error Message

[MrNegaBlox]

This is the stack trace I got and I was wondering how I fix this, it doesn't seem to be about my code, it says a file is missing  but I don't know what it is. Is 1.7.10 unstable?

It is looking for your Minecraft assets folder, which Gradle should set up for you automatically. Open the folder it specifies and see if you have both an 'indexes' and 'objects' folder; if you do, try restarting your IDE, sometimes that's all it needs; if not, try running 'gradlew --refresh-dependencies setupDecompWorkspace' again.
