The forge server runs fine by itself, but when I add my mod this error appears:

What could I have done wrong?

Upload a repo, it seems like there's a "sides" problem

Is there any way I can find where in my code this error is happening?

Caused by: java.lang.ClassNotFoundException: net.minecraft.client.Minecraft

My guess is you are using Minecraft in somewhere that's not on client

Wait you can’t Minecraft.getMinecraft() on the server???

no, it's client only

WHAAAATTTT???!????!!!!??

thank you so much!

ill work on fixing it!

If you look into Minecraft.java, it has a annotation on it

@OnlyIn(Dist.CLIENT)

tells you this is only available on a specific side

Is that better than using @SideOnly(Side.CLIENT)?

They are the same thing, which 

@OnlyIn(Dist.CLIENT)

is the replacement of that in newer versions.

Also quote from the docs

There is little to no reason for using this annotation directly

Or in the words of LexManos,

No, You should NEVER be using these annotations.

Not even for your rendering code.

Not even if the overridden method has it.

NEVER.

If you run into sided issues, bypass it using proper side checks.

If you never call the client side code, on the dedicated server, it doesn't matter if the classes are in your jar.

 

If some other mod/code reflectively access your class in the one specific case where you have a method with a sided class in your signature. Then there can be issues. However those issues are on the side of whomever is reflecting into you unnecessarily.
