PROBLEM DETAIL:

java.lang.IllegalArgumentExcption: Cannot remap access widener from namespace 'srg'. Expected: 'intermediary'

When the IDEA is importing the mod via curse.maven in build.gradle. and got an error during the importing which is shown above. IIRC Forge version don't have the AccessWidener (AW). Only FABRIC has it. If you can take a look inside the jar and you'll find it has AW file

No matter what I do, i can't import the FORGE version into the IDEA.

SOLUTION:

Try see if you can configure your IDEA to remove AW from FORGE's side when you compile a new jar.

OTHERS

I had to downgrade the version down to 1.19.2-v2.12 (it don't have AW) so it can be properly imported.

UNRELATED DETAILS:

Every Compat support Another Furniture, I am currently trying to fix the tab issue between FORGE & FABRIC.

FABRIC is fine but FORGE on the other side doesn't use a similar tab setup.
