Minecraft is now crashing after creating armor. When I try to run it it asks me what class to run, and I choose the start class. And then it crashes with this

 

"java.lang.NullPointerException: Initializing game
    at net.minecraftforge.fml.loading.BackgroundWaiter.runAndTick(BackgroundWaiter.java:32) ~[forge-1.15.2-31.2.0_mapped_snapshot_20200514-1.15.1-launcher.jar:31.2] {}

I have no idea what to do. Here is the link to my github --> https://github.com/Foonicular/AMCMod

 

Thanks in advance to any1 who helps.

The debug.log file in the logs folder? I can't find a way to show that... It's really long.

Gist Github.

Okay, i found my debug.log file in my logs folder in eclipse, this is what it said, I assume what it cant find is pretty important XD

 

[31Oct2020 14:00:41.020] [Render thread/ERROR] [net.minecraft.client.resources.ResourceIndex/]: Can't find the resource index file: assets\indexes\1.15.json
[31Oct2020 14:00:41.104] [Render thread/INFO] [net.minecraft.client.Minecraft/]: Setting user: Player200
 

So...

Put the whole thing into a gist...

And let us decide the important bits.

Okay, so I was looking in the debug.log file in my logs folder, and that's all I found... (The missing 1.15.json file) Is there a different file I should be looking for? Thanks once again.

 

Just so you know, it gets nowhere before crashing, it crashes in like 5 seconds maybe less.

Again, post the whole debug.log.

Okay, I am sure that I am just being really dumb at this point... but... Where do I find the debug.log? I was looking at a file called debug.log in my logs folder in eclipse and this --> [31Oct2020 14:00:41.020] [Render thread/ERROR] [net.minecraft.client.resources.ResourceIndex/]: Can't find the resource index file: assets\indexes\1.15.json
[31Oct2020 14:00:41.104] [Render thread/INFO] [net.minecraft.client.Minecraft/]: Setting user: Player200

is all that I found. I say again, it crashes almost immediately. IDK what I need to show. If there is a different file that I just have not showed yet, all I need is where to find it.

 

Also, when I tried to run it the first time, it asked which class to run, I chose the start class... is there possibly a different class I need to run?

So sorry about that, here is the gist --> https://gist.github.com/Foonicular/b1bb2ab37364aedc1fe42d971c3da27b

 

and this is the raw --> https://gist.githubusercontent.com/Foonicular/b1bb2ab37364aedc1fe42d971c3da27b/raw/15dd805212df1399be9a6c05ba8eb9df59f98c6c/debug.log

 

just in case this helps, I cannot run client... I think that the runClient may be broken. I have tried copying the src code into a new project, but that wont work either...

Edited November 2, 20204 yr by foonicular

Okay I just figured it out, I had to choose to run a configuration... Then I could pick runClient and it works now. Hope this helps any1 else who might need it. And thanks to you guys for trying to help!
