We will use Spring Initializr (http://start.spring.io) to initialize a Kotlin project. The following screenshot shows the Group and ArtifactId to choose from:

The following are a couple of important things to note:

• Choose Web as the dependency
• Choose Kotlin as the language (second drop-down at the top of the screenshot)
• Click on Generate Project and import the downloaded project into the eclipse as a Maven project

The following screenshot shows the structure of the generated project:

The following are some of the important things to note:

• src/main/kotlin: This is the folder where all the Kotlin source code is present. This is similar to src/main/java in a Java project.
• src/test/kotlin: This is the folder where all the Kotlin test code is present. This is similar to src/test/java in a Java project.
• Resource folders are the same as a typical Java project--src/main/resources and src/test/resources.
• Instead of JRE, Kotlin Runtime Library is used as the execution environment.
