As the titles says, I'm trying to run compatibility between my mod and another mod. (MC version 1.14.4) The other mod's Jar file loads into my IDE just fine, I can access it's library and import it just fine and have no build errors in my IDE. But when I try to compile to either build or run I receive a compileJava error and it's unable to find said imports from the other mod that were working inside the IDE. I run the basic check to see if the mod is loaded before calling any of the classes that use it's imports, if(ModList.get().isLoaded which I know works. I know that the mod jar also works. My code otherwise works when I'm not calling in the others mods imports, the mods jar works fine, so I'm at a bit of a loss as to why I would be getting compile. Even when the specific class is not called or there is only just the import, I still run into this error. So I'm not really sure as to why I'm running into this error, I've done a clear reinstall of forge to the latest version with no difference, is there a specific location where I'm suppose to place the other mods jar file in the mkd? or something else small that I'm missing? Any help would be appreciated.
