Building an uberjar with Gradle

Question

I want to build an uberjar (AKA fatjar) that includes all the transitive dependencies of the project. What lines do I need to add to build.gradle?

This is what I currently have:

task uberjar(type: Jar) {     from files(sourceSets.main.output.classesDir)      manifest {         attributes 'Implementation-Title': 'Foobar',                 'Implementation-Version': version,                 'Built-By': System.getProperty('user.name'),                 'Built-Date': new Date(),                 'Built-JDK': System.getProperty('java.version'),                 'Main-Class': mainClassName     } } 

Answer 1

I replaced the task uberjar(.. with the following:

jar {     from(configurations.compile.collect { it.isDirectory() ? it : zipTree(it) }) {         exclude "META-INF/*.SF"         exclude "META-INF/*.DSA"         exclude "META-INF/*.RSA"     }      manifest {         attributes 'Implementation-Title': 'Foobar',                 'Implementation-Version': version,                 'Built-By': System.getProperty('user.name'),                 'Built-Date': new Date(),                 'Built-JDK': System.getProperty('java.version'),                 'Main-Class': mainClassName     } } 

The exclusions are needed because in their absence you will hit this issue.

Have you tried the fatjar example in the gradle cookbook?

What you're looking for is the shadow plugin for gradle
