[NoClassDeffounder - SOLVED] Signature files missing Error

Modder123 · July 5, 2017

So, I made my own Mod, and i Tried to Run it with the 1.8FML Versison (I used the MDK for 1.8, i tried download the 1.8 forge but it gave me 1.8.9 instead so i was need to use to the 1.8FML Forge Versison)

And when i try Run it on my MC it keeps getting the Error "java.lang.NoClassSeffounder" Error,

My Code is Completly fine and All.

What's Wrong?

Do i need To Add a specific code to my Mod?

By the way, i did exchanged it to a Jar file. so it wont be that problem.

Please Answer.

Thanks.

Post the FML log (logs/fml-client-latest.log in the game directory) using Gist or Pastebin.

How exactly did you build you mod?

You appear to be running FML without Forge, but your mod uses at least one class from Forge (and using FML by itself isn't supported). Forge includes FML, so use Forge.

You should be able to download a 1.8 version of Forge from the main Files site.

I Tried that, but when it opening the minecraft it opens 1.8.9 And not 1.8 as the download (main site) said.

but I'll try again.

The game loaded up But the Mod didn't work (it said a Signature Error)

is there Fix for that?

That's the crash report, not the FML log. As I said previously, the FML log is the logs/fml-client-latest.log file in the game directory.

Did you select the correct Forge version in the launcher profile?

That's not the full log. It doesn't appear to be the FML log, either.

The missing signature data error is bad if you're running Minecraft outside of the development environment, but it doesn't crash the game.

That's closer, but it's still not the FML log. The FML log should have several DEBUG and TRACE messages, the log you linked doesn't.

There's no error in that log. What issue are you currently experiencing?

OK, firstable, why you Respond like 30 minutes after i reply, And I seriously Don't understand how that's not the Log i Litearlly went to my Logs floder in .minecraft And Took it from there... Secondly, my Code is all Good but the Mod wont work.

Aka Signature problem.

Thats the problem.

Are you absolutely sure that you posted fml-client-latest.log? Like I said, it doesn't appear to be the correct log.

"The mod doesn't work" doesn't really tell me anything. How does it not work?

What's the "signature problem"? If you mean the "FML appears to be missing any signature data. This is not a good thing" message, I explained that this is bad but it doesn't crash the game or stop anything from working.

For some reason, in the Logs floder in .minecraft I cannot find anything like You mentioded.

I see there files with Dates like: 2017-07-05 And not fml-client-lastest.log or something like that.

And by what i mean That mod doesn't work:

Ok, basically i made a Mod thats if you click a Specific Button (Basically i added a Keybind to my mod) it will execute a Command to the Server.

The thing is, it wont Send it, maybe it does send but i dont see the message, Anyways, Just incase I may coded wrong the

Send Command to the Server code, here is the Codes:

KeyBinds:https://pastebin.com/hprVPhAd

KeybindInputHandler(the class which executes the Code for the keybind.):https://pastebin.com/Kp2QY1g1

Quick Note - About the Command inside this ^ code i typed there a command that the Server added to himself, basically, a Custom Command of the server i use the Mod to. (the server is not mine)

NOTE: Those are not ALL of the mod Class codes.

I Hope you can tell me whats wrong with my code or with the mod.

Thanks.

EntityPlayerSP#sendChatMessage is the correct method to send a chat message from the client (which may be a command). ClientCommandHandler#executeCommand can only execute client-side commands, not server-side commands.

KeyBindings should be checked in ClientTickEvent (make sure you check TickEvent#phase to avoid checking the KeyBindings in both phases of the event) rather than KeyInputEvent.

Have you registered an instance of KeyInputHandler with the appropriate event bus? Is the onKeyInput method being called? Set a breakpoint in the method and run Minecraft in debug mode if you're not sure.

Wait, Can you give me an Example of where to put the Command In? it would help me.

Where exactly to Put those methods?

I'm not the best In those Stuff... You can just ignore that message if you want... i'm really not the best in Java Coding...

Uh.. can you maybe Make a pastebin Explaining where goes each thing? it would help me a bit...

Thanks.

So you've set a breakpoint inside the if statement in onKeyInput and it was hit? Did you try stepping through the code to see what happened?

The way you're sending the command chat message with EntityPlayerSP#sendChatMessage should work.

ClientTickEvent is an event just like KeyInputEvent, you subscribe to it in the same way. It's even fired on the same event bus (the FML bus).

Forge's documentation has an introduction to events here.
