ClassNotFoundException for API classes

[Jongh]

So I'm trying to make a mod that uses the Hypixel api. I have a libs folder in the same mod folder that contains the eclipse, gradle, src folders. In that libs folder I have the api jar that I've added to Build Path in eclipse, and I also included it as a dependency in the build.gradle file using:

 

dependencies {

    compile files ("libs/hypixeldev-publicapi.jar")

}

 

Here's a snip of the class hierarchy and some imports:

 

The mod runs fine in Eclipse, but when I build the mod and try running it with Minecraft the game crashes with a ton of ClassNotFoundExceptions, I think because it couldn't find any of the classes in the API.

 

Does anyone know how I can fix this?

Are you including the Hypixel library in your mods folder when you run via Minecraft?

[Jongh]

No, just my mod.

 

But I'd rather prefer it if I didn't have to include other mods for mine to work... Is there any way I can bundle the hypixel api jar into my mod somehow? I'm pretty sure this is possible.

No, just my mod.

Use the Shadow Gradle plugin. I have an example here.

Hey, I'm trying to figure out how to use this and I'm not finding much.

 

Is there any tutorial for installing gradle plugins? I can't seem to find any. And just like in general I'm sort of lost how to use this shadow plugin... There's just so much information on the Shadow Plugin user guide and I'm having some difficulty filtering it.

 

Any help would be much appreciated.

Use the Gradle Plugin syntax in section 1.2 of the user guide (I also use this in the build.gradle I linked).

• Add the dependency you want to shadow as normal in the

  dependencies

  block
  

• In the

  shadowJar

  block:
  

  • Filter which dependencies are shadowed using the

    dependencies

    block
    

  • Relocate the classes from the shadowed dependencies to your own package using

    relocate

    
    

  • Set

    classifier

    to

    ''

    to overwrite the default JAR with the fat JAR produced by Shadow

   

  [*]Tell ForgeGradle to reobfuscate the output of the

  shadowJar

  task in the

  reobf

  block

Ok so I wasn't entirely sure how it would work for jars, because your example code seems to be only including a single class dependency while I'm using a whole jar.. So I just added it in like this:

 

https://gist.github.com/hjongh/f6f97391d2e150c4e3bfc9148a0592a8

 

But when I try to build, cmd shows "could not find method shadowJar()" which is not even a problem with how I included the jar dependency I think.

 

EDIT: WAIT DERP IT LOOKS LIKE MY PLUGIN SECTION IS COMMENTED OUT LET ME TRY AGAIN BRB

 

EDIT2: OK IT WORKS NOW BUT NOW THE WAY I USED THE JAR AS A DEPENDCY IS CAUSING A BUILD ERROR

[Choonster]

I'm shadowing the entire Fluent API JAR, not just a single class.

[Choonster]

The

relocate

statement in the

shadowJar

block relocates a package, not a JAR.

Woahhhhkayyyy I got it to build successfully and not crash my Minecraft! Thanks so much for the help man really appreciate it.

 

Now to finish my mod haha

 

Thanks again!
