Hello. I am trying to use MongoDB on a mod, I have written 

compile 'org.mongodb:mongodb-driver-sync:4.2.3'

in the dependencies (build.gradle), when I start the mod by starting "runClient" on IntelliJ it works perfectly. But when I drop the file generated (build/libs/name-version.jar) using "gradlew build" it shows me this error:

java.lang.NoClassDefFoundError: org/bson/conversions/Bson

What can I do? Should I import the library using other method? Which method? Thanks!

You need to ship any libraries with your mod.

Alright. But is the player going to need to download two files instead of just one? And, do you know how can I do it?

You can use shading as well, look at the Gradle Shadow plugin.

Okay, I have tried and it created a file larger but it doesn't work. It doesn't show up in Minecraft. Writing this in the bottom of my build.gradle file:

buildscript {
  repositories {
    maven {
      url "https://plugins.gradle.org/m2/"
    }
  }
  dependencies {
    classpath "com.github.jengelman.gradle.plugins:shadow:6.1.0"
  }
}

apply plugin: "com.github.johnrengelman.shadow"

 

Also, I have tried using Forge shading like this:

configurations {
    shade
    compile.extendsFrom shade
}
dependencies {
    minecraft 'net.minecraftforge:forge:1.16.5-36.1.0'
    shade 'org.mongodb:mongodb-driver-sync:4.2.3'
}
jar {
    manifest {
        attributes([
            ...
        ])
    }
    configurations.shade.each { dep ->
        from(project.zipTree(dep)){
            exclude 'META-INF', 'META-INF/**'
        }
    }
}

But "shade" in dependencies shows this error: "No candidates found for method call shade." 
What can I do? Thanks for you help

Okay. I have tried again with shadow, I did it like it's shown here: https://github.com/Choonster-Minecraft-Mods/GradleShadowTestMod/blob/master/build.gradle but no, it doesn't work. It shows me this error: 

com.google.common.util.concurrent.ExecutionError: java.lang.NoClassDefFoundError: org/gradle/api/internal/java/JavaLibrary

What can I do?

 

UPDATE:

If it's needed, my build.gradle:

UPDATE:

Also tried https://www.baeldung.com/gradle-fat-jar, it just created a bigger file which doesn't work, it doesn't show up in Minecraft mods.
