I'm building a votifier that runs on forge to use on my own server, since I'm going pure forge and no cauldron. While testing in IDEA, the mod compiled and ran successfully, however, when I build it (with /gradlew build) and run it on a server, I get a ClassDefNotFoundException. My project structure is:

 

src

-main

--java

---com.direnode.forgevotifier

----cryptography

-----KeyGenerator

-----RSA

-----RSARead

----handler

-----ConfigurationHandler

-----PlayerHandler

----reference

and some other stuff, follows that same order

At first it also happened with the KeyGen class, but I generated them in the IDEA server and just transferred it.

Did you reference any of the client classes or use some @SideOnly?

You should not do that on Dedicated Server.

NEVER use sideonly ,except of if you are 100% sure what you are doing

Don't have any @SideOnly tags, it's supposed to be server-only, so I just set acceptableRemoteVersions = "*" in the @Mod

The KeyPair and RSARead classes are mostly just encrypting and decrypting stuff, using java.security

Then please post the code of the class.

Main class (ForgeVotifier): http://pastebin.com/tK6qEZ6v

RSARead: http://pastebin.com/7aFB8cCB

KeyGenerator: http://pastebin.com/VhdLc1tL

 

Does it work if you install it in a dedicated server without all those other mods?

 

If you browse through your built jar, can you find the RSARead class in expected path?

I think I found the problem. While searching the .jar to reply to

I noticed that the cryptography package is called "Cryptography" instead of "cryptography" so when it looks for cryptography.KeyGen, or RSARead, it can't find it

It's strange, since the package name is cryptography, and the package of the classes is set to com.direnode.forgevotifier.cryptography

Got it, worked now. Had to delete the classes folder in the build folder and re-build. Thanks to everyone for the support!
