Having trouble shading with my mod

[fernthedev]

So basically I can run the mod just fine when I run the "runClient" task and everything works great. However, when I compile it with shadowJar it has all the libraries, yet when Minecraft loads it, it says it can't be found.

Here's the log

---- Minecraft Crash Report ----

I've tried using many ways of shading or making fat jars but they all keep saying the exact same error.

[MDW01]

Yea this can be a bit tricky. Personally, the way I would do it is by adding that repository to yours using a git submodule. This shouldn't be an issue since they have an MIT license just make sure to give them credit. It will then get compiled directly into your code. It is pretty easy to keep the library up to date using git modules and they make it even easier to change the library if you need to.

So you're suggesting I add my project as github repository, adding which "repository" as a git submodule? Also I have given them credit in the mcmod.info file

  "modid": "discordmod",
  "name": "Discord",

}
]

 

Edit:

this error keeps appearing no matter what way I fatjar/shade it, and I opened it with winrar and it does exist inside it

Sorry, I guess what I said wasn't very clear. What I mean is that you add the libraries git repository into your project's repository as a git submodule.

[MDW01]

Heres some more information on git submodules.

https://git-scm.com/book/en/v2/Git-Tools-Submodules

 

Heres a good example from open blocks. They added the open mods lib to the open blocks repository with a git submodule.

[fernthedev]

I’m pretty new to using gradle (I used maven and did plugin development back then) and never had to shade

What?!

 

@fernthedev Mods cannot contain code in the org.apache package. You must relocate the repackaged code to somewhere else.

So what I understand from this is I have to download the library and add it locally with a different name?

No. Use this: https://github.com/johnrengelman/shadow

I've been using that and org.apache.lang.systemutils is included inside it but Minecraft keeps showing the error it's not showing

I've also tried other methods of fat jar-ing it and it still causes the exact error. This is being thrown because the library I'm using for the discord API is using that class (I compiled the app myself and it does indeed have the maven shading plugin in the pom.xml and is included)

Extract the jar and see for yourself what I'm dealing with.

You need to change the package, not just include the dependency.

Like I said, mods cannot contain code in the org.apache package.

 

Thanks I didn't know shadow could do this Really helpful.

Actually now I'm receiving this error. I added logger to gradle but still.

Caused by: java.lang.NoClassDefFoundError: shadow/org/apache/logging/log4j/Logger

Jar with the relocated package

[fernthedev]

Actually nevermind, I fixed that last issue with relocating. However, this issue is very odd.
