How to create a Dropwizard project with gradle?

Question

I am on a Linux machine with Idea IntelliJ and I would like to create a Dropwizard project with gradle. With maven archetypes this job would be very easy.

mvn archetype:generate 
-DarchetypeGroupId=io.dropwizard.archetypes 
-DarchetypeArtifactId=java-simple 
-DarchetypeVersion=[REPLACE ME WITH A VALID DROPWIZARD VERSION]

For gradle I am struggling to get going. As I checked out other post I was wondering if what I did was correct:

// Needed Instead of the Shade plug in 
plugins {
    id 'com.github.johnrengelman.shadow' version '2.0.1'
}

version '1.0-SNAPSHOT'
group 'org.example.sampleName'
description 'Sample Dropwizard REST '

apply plugin: 'java'
apply plugin: 'application'

repositories {
    mavenCentral()
}

dependencies {
    compile 'io.dropwizard:dropwizard-core:1.2.0'

    testCompile 'junit:junit:4.12'
}

mainClassName = 'org.example.sampleName.SampleApplication'

run {
    args = ['server', 'config.yml']
}

shadowJar {
    mergeServiceFiles()
    exclude 'META-INF/*.DSA', 'META-INF/*.RSA', 'META-INF/*.SF'

}

jar {
    manifest {
        attributes 'Main-Class': mainClassName
    }
}

Then I just run gradle shadowJar and then run java -jar build/SampleApplication.jar server config.yml . Is this correct? And is the line testCompile 'junit:junit:4.12' enough for the unit test?

You could use this Yeoman generator:

If you have npm installed.

The line testCompile 'junit:junit:4.12' is sufficient, yes.

You can also search on github for examples, like this one: https://github.com/kishaningithub/dropwizard-gradle
