thank you !

how can i create a SimpleChannel and registerMessage in 1.13.2 ? can you give a example?

how to register ItemGroup? ok, i know. just put it, dont need register.

fixed, the problem is java version, i was used java 11, and ForgeMDK just working with java 8

I was deleted caches and try with forge-1.13.2-25.0.64-mdk, still dont working.

when i execute runClient, have this error Task :compileJava FAILED FAILURE: Build failed with an exception. * What went wrong: Could not resolve all files for configuration ':compileClasspath'. > Could not find net.minecraftforge:forge:1.13.2-25.0.63_mapped_snapshot_20180921-1.13.
