I also like to put this in a file named Core.kt which should be added to the src/main/kotlin directory as New ➡ Kotlin File/Class.Īt this point there should be no build errors or issues with Gradle. Personally I’m a fan of the 2nd method as I feel it allows for better organization. The first involves creating a fun main at the root level of a file while the second requires creating an object with a static main method inside of it. There are two approaches to doing this and differ really only in style than anything else. We’ll need to create a main entrypoint function where the app “starts”. A summary of these changes can be found in these commits. Once these changes are made the Gradle script should correctly build and start code highlighting. We’ll also add a publishing section that we can use down the road for building a Maven dependency. For instance, in the plugins section, items such as This will result in some errors popping up in the console as IntelliJ attempts to rebuild a now “broken” Gradle file but no biggie, we can quickly fix those. While the default Gradle script file is fine, since we are using Kotlin let’s go ahead and make our Gradle script Kotlin as well. lower case project names they are mostly up to personal styles and can be modified in the project settings or Gradle files.Ī summary of these changes can be found in these commits. Note that while there are subtle differences between capitalized vs. Ensure a Java SDK is present in the Project SDK field which should be pre-filled with a sensible default.Ĭlicking Next will take you to a screen asking for the name of your project.

Click on File ➡ New ➡ Project.įor the type of project select Gradle ➡ Kotlin/JVM. Let’s start with opening up IntelliJ and creating a new project. Note that this will heavily reference the Batil repo. We will also make use of Github, Gradle and JetBrain’s IntelliJ IDEA, the gold standard in Java IDEs. We will be building a “Hello World” command-line application packaged up as a JAR file, a format just about every Java developer should be familiar with.

Many folks associate Kotlin with Android but its uses extend far beyond programming for mobile.
