[1.15.2]Using mods in development workspace

[undertrox]

Hello,

I'm trying to make an addon for another mod, which obviously requires me to test it with that mod loaded, but when I put any mod into the run/mods folder, Minecraft will start with an error message, saying "the mod encountered an error during the load_registries phase" (depending on the mod, it is sometimes a different phase). The log usually shows either a NoSuchFieldError or a NoSuchMethodError, again, depending on what mod I try to load.

I even tried using deobfuscated jars of mods that have them, but then I just get a different NoSuchFieldError. The file I uploaded is the log for when I tried to load Biomes o Plenty, though I doubt it will help.

Does anyone know what I need to do differently?

Hi

 

That used to work in older versions but I haven't tried it since 1.12.2.  If no-one here has an answer, you might try raising it as an issue on the Forge github.  It does sound like a bug.
