I am making a mod in VSCode and everything was working properly. Now, for some reason, whenever I try to execute gradlew runClient it fails and says "Execution failed for task :compileJava". If someone could tell me what was wrong I would appreciate it.

Run gradle with the --info and --debug flags and provide the output in a gist or pastebin.

Here is my output:

Seems to be a bunch of issues with your mod. Assuming that this information is correctly linked, I would guess there's something wrong within your build.gradle, if you would so kindly provide it.

I ended up figuring it out. I hadn't imported the correct packages. Thank you for all the help you have given.
