在 gradle 中创建影子 jar？

Question

tasks.register('uberJar', Jar) {
    archiveClassifier = 'Uber'

    manifest {
        attributes["Main-Class"] = mainClassName
    }

    from sourceSets.main.output

    dependsOn configurations.runtimeClasspath
    from {
        configurations.runtimeClasspath.findAll { it.name.endsWith('jar') }.collect { zipTree(it) }
    }
}

This doesn't seem to be working... I'm trying to make an uber jar with multiple dependencies, One-Jar seems to be outdated, and I can't use either the default gradle uberJar builder or shadow jar.

Answer 1

Don't reinvent the wheel and use the plugin for that. In the most simple scenario (which would probably work in your case), it's just a matter of:

plugins {
  id 'com.github.johnrengelman.shadow' version '7.1.2'
}

And then:

./gradlew shadowJar
