How do I build an OS X Java Application Bundle in IntelliJ IDEA?

Question

I'm trying to build a Java application for the mac in IntelliJ IDEA. The Apple Developer docs say I need to make a Java Application Bundle in order to support things like dock icons, application names etc, but I'm not sure how to set up a build configuration to do all this from within IntelliJ. Can anybody shed some light on this?

Here's how I dit it (MacOS 10.10 + IntelliJ IDEA 15 + JDK 1.8):

1. Download Oracle Java Application Bundler and place copy it into /lib directory of your project.
2. File → Project Structure → Artifacts → Add (+) → JAR → From modules With Dependecies... → Choose Main class → OK.
3. Build → Build Artifacts... → Generate jar in /out/artifacts/...

4. Create build.xml at your project's root:

   <?xml version="1.0" encoding="UTF-8"?>
   <project name="Test" default="bundle-test" basedir=".">
       <taskdef name="bundleapp" 
           classname="com.oracle.appbundler.AppBundlerTask" 
           classpath="lib/appbundler-1.0.jar" />    
       <target name="bundle-test">
           <bundleapp outputdirectory="out"
               name="Test"
               displayname="Test"
               identifier="Test"
               mainclassname="Main">
               <classpath file="out/artifacts/test_jar/test.jar" />
           </bundleapp>
       </target>
   </project>
   

5. At the Ant Build panel (View → Tool Windows → Ant Build) click Add (+) and chose your build.xml and press Run button.
6. Find your app in /out directory of your project.

IntelliJ IDEA doesn't support creating such bundles. You can use Ant or some external tool to automate this process.
