Starting Coding of a Mod, but Minecraft is not loading up

I'm starting coding of a mod using the fabric-example-mod template, and I just finished customizing fabric.mod.json and creating the new java file, but when I try to launch this error happens and the game crashes. I have very little experience so I have no idea what's going on.

It also says that Minecraft failed to verify authentication before the crash report.

So your class is at com.d3rpym00.blockCompression To me it wounds like it should be com.d3rpym00.BlockCompression. Could you screenshot in IDE so I can cross verify

commented

Yes, here is the screenshot.
error

That entrypoint value doesn't point fully to the class but instead just to the package.

The value should be com.d3rpym00.blockCompression.blockCompression

commented

Oh ok, I changed it and it works now, thanks!

Caused by: java.lang.ClassNotFoundException: com.d3rpym00.blockCompression

Have you verified your main entrypoint in your fabric.mod.json points to the correct class

It does point to the correct class, I just verified.
