Answer 1

You could use the ShadowJar plugin to build a fat jar:

import com.github.jengelman.gradle.plugins.shadow.tasks.ShadowJar

buildscript {
    repositories {
        mavenCentral()
        gradleScriptKotlin()
    }
    dependencies {
        classpath(kotlinModule("gradle-plugin"))
        classpath("com.github.jengelman.gradle.plugins:shadow:1.2.3")
    }
}

apply {
    plugin("kotlin")
    plugin("com.github.johnrengelman.shadow")
}

repositories {
    mavenCentral()
}

val shadowJar: ShadowJar by tasks
shadowJar.apply {
    manifest.attributes.apply {
        put("Implementation-Title", "Gradle Jar File Example")
        put("Implementation-Version" version)
        put("Main-Class", "com.mkyong.DateUtils")
    }

    baseName = project.name + "-all"
}

Simply run the task with 'shadowJar'.
