[1.12.2] Running compiled mods in the workspace /run/mods folder

I need to run several external mods along with the mod I'm developing for testing purposes. I have been adding my mods to the /run/mods folder, however in 99% of cases, this causes a crash with a null reference exception.

 

I have tried:

- Universal and deobfuscated versions of each mod

- Deobfuscated versions of mods created using BON2

- Using CodeChickenLib which reportedly allows running obfuscated mods from /run/mods

- Adding MCP mappings for 1.12.2 to my MCP folder

 

Universal and deobfuscated both from the developers of the mods and from using BON2 makes no difference and crashes all the same.

Using CodeChickenLib in the mod folder causes a crash just like any other mod.

 

Any information I can find on this is years old, I've googled extensively and checked numerous forums and old threads.

 

Here's an example of a crash from CodeChickenLib, unobfuscated jar

Go to Run/"Run Configurations ...", select in tree left "Java Application"/<Name-of-your-ProjectFolder>_Client, go to "Arguments" Tab and remove in "VM arguments" "-DFORGE_FORCE_FRAME_RECALC=true" what should be the whole content of that textfield.

This stops FML/Gradle to use any mod in its deobfuscated version; what means methods names, variables etc. in the foreign mod jar file don't get renamed into a human readable version while loading.
With deobfuscation the mod become unable to load parts of itself by reference the name of classes/modules. If you want to add references to other mods (e.g. for dependencies) in your own mod you might need a more elaborated method.
