[1.7.10] Mod suddenly crashes after building?

Posted September 11, 201510 yr

Hi,

I've build my mod many times and have never had this error before. After running gradlew build, my mod crashes the game on startup. There is no problem in my eclipse workspace, and the class the game crashed on is in fact in the correct path in the jar. Full crash report:

Description: There was a severe problem during mod loading that has caused the game to fail

Yep, and already tried doing that several times.

So, I fixed the crash by removing my overridden

verifySellingItem

in EntityDivineRPGVillager. No idea why that'd made it crash. EntityDivineRPGVillager in case it's relevant:
