This guide comes with a number of sample plugins available from dedicated intellij-sdk-code-samples GitHub repository.
Please see README.md which lists all available code samples with a short description.
Each sample is stored in a dedicated folder and is accompanied by its own README.md. Links to the corresponding tutorial or reference page in this tutorial, as well as a list of relevant show-cased elements are provided.
All sample plugins are based on Gradle, see Creating a Plugin Gradle Project to get started.
Additionally, the Working with Gradle in IntelliJ IDEA screencast offers a thorough introduction to Gradle functionality inside IntelliJ IDEA.

Make sure plugins Git, Gradle, and Plugin DevKit are enabled.
Clone the intellij-sdk-code-samples GitHub repository via Git | Clone.... After successful cloning, the IDE suggests opening the project.
Select the code sample(s) to import via the Gradle tool window.
Alternatively, import all code samples available by choosing _gradleCompositeBuild, which links all Gradle projects in a Composite Build.
After successful import, the project appears in the Gradle tool window tree as a new node. Assign a Java 11 SDK in for Gradle JVM. Invoke Reload All Gradle Projects from the Gradle tool window toolbar if necessary.
