I did in fact delete both, tried it again as well, and its been several reboots still nothing works. I have another gradle / libgdx project and it works fine...

It doesn't find anything in the search, a clue that something is amiss.

Sadly none of this worked either...

Still no cigar. I dragged and dropped my old src files into the project folder, updated the toml file, rebuilt again but it still doesn't work.

Thanks did the trick, it's been a while since I've done this stuff. Another issue now, it's says "Error: Could not find or load main class net.minecraftforge.userdev.LaunchTesting" when I hit run.

Just downloaded the recommended forge version for Minecraft 1.16.4 and followed all instructions. I ran gradlew genEclipseRuns then imported the project into Eclipse IDE but its giving me unresolved import errors for any non core java import. This means that org.apache and all the net.minecraftforge imports are underlined in red with the message "the import cannot be resolved". Please help thanks.

How?

I knew this already, I was wondering if there was a way to upgrade my existing eclipse environment without having to download a new MDK.

I've read that you change the version in build.gradle to achieve this, but I'm not sure how. There is a many digit number in there, what do I change it to?

I see this : '20190719-1.14.3' in that file, not sure what to change it to for the latest version of mdk for version 1.16

Okay so I have a Chunk Generator, World Type, and Biome Provider. I will eventually alter the chunk generator (it's vanilla right now), but first I need to know how to only have certain biomes spawn. Lets say I want to the whole world to be only desert and badlands for example.

I copied how they did it, not any of their specific code itself. My world type currently generates the same as vanilla, I just learned how to link the classes together from BOP's source code.

Actually I got it, I looked at the Biome's O Plenty GitHub and copied their implementation. I forgot to change the repository branch to 1.14 at first, which is why I wasn't getting the correct results.

Bump because I changed / updated the question.
