Error I Can't Fix

[DroidCrafterMC]

I'm experiencing an error with IntelliJ that I can't seem to fix. I've tried everything online but it just won't work. I've checked over most of my code and it's all okay.

This is the error message:
Unable to load class 'Class 'ijresolvers1_cfmb9fkeoe91vvthlgdqtrsfz$1' not found in class loader 'VisitableURLClassLoader(ClassLoaderScopeIdentifier.Id{coreAndPlugins:init-file:/C:/Users/user/AppData/Local/Temp/ijresolvers1.gradle:groovy-dsl:C:\Users\user\AppData\Local\Temp\ijresolvers1.gradle:InitScript(local)})' of type 'org.gradle.internal.classloader.VisitableURLClassLoader'.' Class 'ijresolvers1_cfmb9fkeoe91vvthlgdqtrsfz$1' not found in class loader 'VisitableURLClassLoader(ClassLoaderScopeIdentifier.Id{coreAndPlugins:init-file:/C:/Users/user/AppData/Local/Temp/ijresolvers1.gradle:groovy-dsl:C:\Users\user\AppData\Local\Temp\ijresolvers1.gradle:InitScript(local)})' of type 'org.gradle.internal.classloader.VisitableURLClassLoader'.

I really don't know what to do...
