Hello,slately I've been running into a really annoying problem. I'm making a mod and trying to use a dependency from jitpack, but it's failing to build, and when it builds, I end up crashing with a NoClassDefFoundError. The dependency I'm trying to use is https://github.com/KevinPriv/HypixelApi4J, and in the coding area it works perfectly fine, but when I build, there are two cases:

 

1, if I add 

jar {
    from configurations.embed.collect { it.isDirectory() ? it : zipTree(it) }
}

 

then it wouldn't build and give me a "java.util.zip.ZipException: duplicate entry: me/kbrewster/exceptions/InvalidSessionException.class", which is a class from the library I'm trying to use.

 

2, if I don't add the thing above, it would build successfully but would end up crashing with a NoClassDefFoundError.

 

Here's my build.gradle: https://www.hastebin.com/egimacuqim.cs

I've never used Gradle before as I'm used to maven, so don't judge me if I did any stupid mistake. Thanks

bump?
