[Solved] [1.12] "NoClassDefFoundError" when launching Server


Recommended Posts

Posted (edited)

Hello everybody,

I recently started making a small Mod for me and a friend which we can use on our server.

So far everything is working out well when I test the Mod in an Single-Player environment, but when i started it as a Server, i got a crash and a NoClassDefFoundError referencing the ICustomModelLoader class.

I know that this class is "Single-Player-only" so im wondering where exactly the Server tries to acces it. I looked through my code but couldnt exactly figure out where, I also googled for similar errors but havent found one close to this and thus didnt find good advice. I also think that i didnt use any !world.isRemote() so far, could it possibly be an error with this? I wanted to implement those later, but to be honest, i dont even exactly know when and when not i have to do this.

The error message im getting is rather long as well, so I dont know wether I only have one error, which is causing all the others, or wether I have multiple ones I have to fix.

Spoiler

If you want to check my source code you can do this here.

If some code is familiar for you, this is propably because I just plainly copied a bit of tutorials, but like I said, I dont want to make a big mod or something, just for me and a friend.

Any help and advice is welcomed.

Thank you in advance,  AleMax

- Check your common proxy for that import

- Make sure a common class does not access a method statically of a class which imports client only stuff

 

These are cases that can happen quickly and without intention (through human error or sometimes when IDEs do stuff) and I have seen them a couple of times already.

Imports are entirely irrelevant. Imports are a compiler fiction.

 

@AleMax All access to client-only classes must be encapsulated through your client proxy. For example: Your ItemTest class directly references ModelLoader. Since your ItemTest class will also be loaded on the server, this will crash.

 Moreover: Code style, issue 1.

Thank you for the help!

I went through my classes and checked for any client-only classes, and then put those in the proxy classes directly (and deleted this nonuse test item lol)

The error log is now basicly reduced to half, but i still got the same error just with the IStateMapper class.

The only classes which use any client only classes are the model and render classes now, should i remove them from there as well, I think that could get a bit difficult or am I doing something fundamentally wrong?

I already saw the thing with the common proxy befor posting, i will probably change it after i got this error fixed ?

I updated my Source code if you want to take a look at it.

You have registered your ClientProxy class with @EventBusSubscriber without specifying a side. This effectively makes your client proxy run on a dedicated server as well. I hope you understand why this is a bad idea.

Incredible. Thank you! Everything is working now.
