Gradle Error While Creating Fat Can

I am trying to create a thick jar using Gradle. I encountered an error similar to this one raised against Gradle . Unfortunately, I don't understand Gradle and Groovy enough to come up with a creative workaround, so I hope someone here can help. I searched online for various workarounds to no avail :(

My conflict with Apache Storm dependencies:

My Gradle code for creating a thick can is as follows:

jar {

    manifest {
        attributes 'Main-Class': mainClassName,
                'Implementation-Version': version
    }

    from {
        configurations.runtime.collect { it.isDirectory() ? it : zipTree(it) }
    }
}

After searching for a whole day looking for a workaround, I found it 5 minutes after I posted my question ...

, , . - , .

jar {

    from(configurations.compile.collect { it.isDirectory() ? it : zipTree(it) }) {
        exclude "META-INF/*.SF"
        exclude "META-INF/LICENSE"
    }

    manifest {
        attributes 'Main-Class': mainClassName,
                'Implementation-Version': version
    }

}
