EDIT: I fixed this issue by reinstalling the Forge MDK.

 

I accidentally posted this topic in the normal Modder Support section, but I switched sections to this one.

 

OS: Windows 10

Java Version: Java 8 (Java 1.8)

OpenJDK build: AdoptOpenJDK

Minecraft version: 1.16.5

GPU: NVIDIA 1660ti

CPU: AMD Ryzen 5900XT 12-core

RAM: 128 GB

 

I cannot build my mod. I used gradlew.bat build in a Command Prompt window. The command output is at the bottom.

If you need more information, ask me!

 

To honour the JVM settings for this build a new JVM will be forked.
Daemon will be stopped at the end of the build stopping after processing
