Well, the title sums it up, i am on a school desktop at my high school, and goguardian blocks the download link (whatever site hosts the download of forge, is there any other way I can download forge for minecraft 1.12.2?
I experienced the same issue. Check if you replaced examplemod with your mod id in ln. 103 of the build.gradle. This line: "args '--mod', 'examplemod', '--all', '--output', file('src/generated/resources/'), '--existing', file('src/main/resources/')"
