Learn how to build plugins using IntelliJ Platform SDK for the JetBrains products by experimenting with our code samples. These samples show you how features work and help you jumpstart your plugins.
Note To start a new plugin project, consider using IntelliJ Platform Plugin Template which offers a pure boilerplate template to make it easier to create a new plugin project.
The code samples can also be found in the IntelliJ SDK Code Samples mirror repository.
To learn more, browse available Extension Points, explore Extension Point usages in open-source plugins using IntelliJ Platform Explorer and learn how to Explore the IntelliJ Platform API.
All Code Samples target the latest GA platform release. Previous releases are made available via tags.
Code Samples depend on the IntelliJ Platform SDK and Gradle as a build system.
The main plugin definition file is stored in the plugin.xml file, which is created according to the Plugin Configuration File documentation.
It describes definitions of the actions, extensions, or listeners provided by the plugin.
Please see Code Samples topic on how to import and run code samples.
In the following table, you may find all available samples provided in the separated directories as stand-alone projects available for running with the Gradle runIde task.
