Experiments with Gradle in the IntelliJ IDEA IDE

I’ve recently started using JetBrain’s IntelliJ IDEA software to develop software written in Groovy at work. It is an excellent package well worth it’s modest price. I have been investigating the differences between the Ultimate edition that my employer purchased for me at work and the community edition that JetBrain’s offers for free. While the extra features available in the Ultimate edition are nice, I have been finding my experience with the community edition as good or better than my previous experiences with Eclipse and Netbeans.

Lately, I have been experimenting with using the Gradle build tool within IDEA. I have figured a lot of things out about it but I am having trouble getting it to build an executable jar file. I’m sure it is just a matter of configuring something correctly within the jar task but I haven’t figure out how to do it yet.

I have learned a lot about IDEA and Gradle but I am just going to have to keep studying until I figure out how to get things to work the way that I want them to. I’ll write a post when I figure out how it’s done.

UPDATE: I figured it out. You just need to add the following lines to your build.gradle file. This includes all of your dependent jars in your executable jar. By the way, substitute the name of your main class  for  ‘org.me.package.Main’.

task fatJar(type: Jar) {
    manifest {
        attributes 'Main-Class': 'org.me.package.Main'
    baseName = project.name + '-all'
    from { configurations.compile.collect { it.isDirectory() ? it : zipTree(it) } }
    with jar
