I'm not sure of this is the correct place to post this, but after reading the FAQ for each subforum here and looking for other places to get support for ForgeFlower I think this might be the closest thing to it.

 

I can build FernFlower using IntelliJ without a problem, but I can't figure out what to do with the ForgeFlower files and couldn't find any documentation to go along with it.

Since there is no src folder included in ForgeFlower-master I'm assuming you have to add the source files from FernFlower, but I don't know the specifics of that. Copying the entire content of fernflower-master or just the source files into the FernFlower folder in ForgeFlower-master didn't seem to have any effect. Just like trying to build ForgeFlower without any extra files it fails stating 

Gradle build daemon disappeared unexpectedly (it may have been killed or may have crashed)

 

I'm running 64bit IntelliJ IDEA Community 2017.3.4 and JDK 1.8.0_1.5.1 and have the latest versions of both ForgeFlower and FernFlower downloaded from the MinecraftForge GitHub.

 

Thanks for reading.

Why? We auto-build ForgeFlower. It's on our maven. Beyond that ForgeFlower is a git-patcher setup so you need to setup the project fully with a properly cloned repo.

Thanks, didn't know that.

Since I can't find "forgeflower" on the maven I'm assuming this is actually it, even though that's not what its called. Is that correct? It decompiled my mod with the exact same problems as FernFlower, so I'm not really sure. I tried to read the 16 entries in FernFlower-Patches but didn't understand them to a degree where I could actually tell if my problems are adressed by ForgeFlower.
