Once again, you need click the link in the notification, choose the modules to configure and the version of the Kotlin plugin (latest stable version or snapshot).Ĭonfiguration files for selected modules will be changed as described here. If you use Maven or Gradle we have also great news: the Kotlin plugin now can configure your project using pom.xml or *.gradle files.
The second path is a points to the headers of the Kotlin library. There are two paths: the first points to the Kotlin Runtime files, which are a JavaScript implementation of Kotlin library. Similar to above, you can then specify where you want the runtime files stored. If you want to compile Kotlin to JavaScript, click as Kotlin (JavaScript) module link in the notification. However, the latter option means that your project will only work on machines where this plugin is installed. You can either choose to copy the JAR library and store it under your project folder (optionally checking it in to VCS) or select Use library from plugin which will merely use the JAR bundled with the plugin in IntelliJ IDEA. Here you can choose which modules need to be configured and a destination path to copy the library to. You’ll be prompted with the following dialog: If you want to compile Kotlin to JVM byte code, click on as Kotlin (Java) module. To configure them, click one of the links in the notification, based on what you need.
If they’re not, you will see the following notification in the upper left corner of the editor: The Kotlin plugin checks that all your modules containing Kotlin files are configured correctly. If you’re using IntelliJ IDEA, it can do this for you automatically.
All you need to do is create a new Kotlin file (*.kt) and tell the environment to use Kotlin. That means that you can easily add Kotlin code to an existing Java project. In your project level adle, add the Kotlin dependency.Kotlin can be freely mixed with Java. So to add it, you'll need to add some dependencies. It's a fancy library, with a lot of features and an accompanying IntelliJ/Android Studio plugin, but it's a library. JetBrains, the company behind the language, has a handy FAQ for this. Before we get started though, you may want to familiarize yourself a bit on how Kotlin works, if you haven't done so already. It also assumes you're using Android Studio. This tutorial is going to go over how you can add Kotlin to an existing Android project that's made in Java. The code might end up looking a little messy if you try to use more advanced features, but it's possible. Meaning, you can access Kotlin APIs from Java. That compatibility works the other way around, too.
