Creating an Uber Jar with Gradle is not working

Question

I’m using the plugin johnrengelman / shadow to create a Uber with some local dependencies, but for some reason unknown is not working.

build.Gradle

/*
 * This file was generated by the Gradle 'init' task.
 */
buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.github.jengelman.gradle.plugins:shadow:5.2.0'
    }
}

plugins {
    id 'java'
    id 'maven-publish'
    id 'com.github.johnrengelman.shadow' version '5.2.0'
}

repositories {
    mavenLocal()
    maven {
        url = 'https://hub.spigotmc.org/nexus/content/repositories/snapshots/'
    }

    maven {
        url = 'https://repo.bukkit.org/content/groups/public/'
    }

    maven {
        url = 'https://repo.maven.apache.org/maven2'
    }
}

shadowJar {
   archiveBaseName = "uber"
   classifier = ''
   archiveVersion = '1.0.0-SNAPSHOT'
}

dependencies {
    compileOnly fileTree(dir: 'lib', include: 'minecraft-colors-*.jar')
    shadow fileTree(dir: 'lib', include: 'knautiluz-http-*.jar')
    shadow fileTree(dir: 'lib', include: 'knautiluz-http-services-*.jar')
    testImplementation 'junit:junit:4.8.1'
    testImplementation 'org.mockito:mockito-all:1.9.5'
    compileOnly 'org.spigotmc:spigot-api:1.15.1-R0.1-SNAPSHOT'
}

group = 'com.knautiluz.lorelei'
version = '1.0.0-SNAPSHOT'
description = 'Knautiluz Verify'
sourceCompatibility = '1.8'

publishing {
    publications {
        maven(MavenPublication) {
            from(components.java)
        }
    }
}

With the commands gradle build and gradle shadowJar the created jars are practically the same, and do not load the mentioned dependencies

Answer 1

Although I see in several places that the way to create Shade is to use the shadow something must have changed in the last version, because I got the Uber jar using implementation in place of shadow getting:

dependencies {
    compileOnly fileTree(dir: 'lib', include: 'minecraft-colors-*.jar')
    implementation fileTree(dir: 'lib', include: 'knautiluz-http-*.jar')
    implementation fileTree(dir: 'lib', include: 'knautiluz-http-services-*.jar')
    testImplementation 'junit:junit:4.8.1'
    testImplementation 'org.mockito:mockito-all:1.9.5'
    compileOnly 'org.spigotmc:spigot-api:1.15.1-R0.1-SNAPSHOT'
}

And so he created my chubby jar with the dependencies.
