How do I create an executable fat JAR with Gradle with implementation dependencies?

I've got a simple project in Gradle 4.6 and would like to make an executable JAR of it. I've tried shadow, gradle-fatjar-plugin, gradle-one-jar, spring-boot-gradle-plugin plugins but neither of them adds my dependencies declared as implementation (I don't have any compile ones). It works with compile e.g. for gradle-one-jar plugin but I would like to have implementation dependencies.

Solution

  • You can use the following code.

    jar {
    manifest {
        attributes(
                'Main-Class': 'com.package.YourClass'
        )
    }
    from {
        configurations.runtimeClasspath.collect { it.isDirectory() ? it : zipTree(it) }
    }
 }

    Be sure to replace com.package.YourClass with the fully qualified class name containing static void main( String args[] ).

    This will pack the runtime dependencies. Check the docs if you need more info.
