Hello everyone,I've been bothered by it for a long time🙃.Here is the excerpt from the code.My jdk is 8 and I've tried JDK17 ,but it did not work.

I've set classpath and JAVA_HOME ,and they seems to be normal.Is anyone can help me?

Any help is appreciated🥺(My English is not fluent,so I perhaps ask u some stupid questions.Pardon me)

I want to write some mods,and I am setting the environment.

To get working with mods, you just need to download an MDK from here: https://files.minecraftforge.net/net/minecraftforge/forge/

Then, extract the zip, rename the folder to whatever you like, and open with your favorite Java IDE.
