How do you change someone's skin to a steve and change the player's in-game name to args[0]?

@FoxinatorDev
Odd. What about clicking the red minus sign (the top left one), and creating an artifact with an entirely new name (using 'From Modules with dependencies')?

 

What do you mean by that?

 

@FoxinatorDev
You select your artifact, click the red minus (the top left most one), and then click the green plus icon, and create a new artifact, but you choose a new name.

 

I don't know how to add a artifact. Sorry, I'm kinda new to API's

 

@FoxinatorDev
You have your artifact named 'Extra Commands'. What I want you to do is select it in the menu to the left, and then click the red minus sign above it where you selected it. Then I want you to click the green plus right next to that, and add a new one, which should fix the problem.

EDIT:
Here's a picture of what I mean:

 

Still an error

@FoxinatorDev
There's nothing wrong with your code. If it's the same 'NoClassDefFoundError' as before, it's to do with the shading. If you have removed and re-added the artifact, can you again post a screenshot of it? It needs to say 'Extracted NameTagChanger...' like in my screenshot above.

 

How did you extract it?

Screenshot:

 

@FoxinatorDev
Please try what I said above. Remove the artifact using the red minus, create a new one using the green plus and choose a new name (IE not Extra Commands).

 

I already did

 

@FoxinatorDev
You didn't pick a new name. I can see that the name is 'Extra Commands' in both screenshots, you know.

 

I deleted it

Then added
Then I clicked on everything in the red shape
Anything I did wrong?

 

@FoxinatorDev
You didn't click 'From Modules with dependencies'. If you click that, you will get it all automatically added for you, including the extracted thing.

 

Oh. I feel dumb.

It is still not working

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

@FoxinatorDev
Right, is it not doing the 'Extracted' thing?

 

It is

Here's a screenshot:

 

@FoxinatorDev
Well, at least we've made progress now. What is the error now?

Also, you shouldn't have spigot.jar set to compile into your project, it will include the entirety of the spigot server, which is just unnecessary.

 

It's the same error.

 

@FoxinatorDev
Are you sure you've recompiled the jar? (Easiest way is to just build project and use that).

If you have, can you open up the jar with a zip program and check if the 'com.bringholm.nametagchanger' package is in there?

 

Yes.

 

@FoxinatorDev
Okay, is the 'com.bringholm.nametagchanger' package inside the jar when you open it with a zip program?

 

What do you mean?

 

@FoxinatorDev
If you open the jar with a zip program of your choice, do you see that the com/bringholm/nametagchanger folder is in there?

 

Yes I do see it.

 

@FoxinatorDev
Right, and that's the jar you're putting in your plugins folder?

Can you copy and paste the error from the console again for me, please.

 

Wait... You put that in the plugins folder too?

 

@FoxinatorDev
No, if you're opening the NameTagChanger jar. What I meant was that you should open the jar that you've compiled and see if that has the package.

 

It does have the package

 

@FoxinatorDev
Then can you copy and paste the error you're getting?
