IntelliJ IDEA 2018.3 Help

Context and Dependency Injection (CDI)

The Context and Dependency Injection (CDI) support in IntelliJ IDEA is based on the Java EE: Context and Dependency Injection plugin. This plugin is bundled with the IDE and enabled by default.

You can enable CDI support when creating a project or module. You can as well add CDI support for an existing module.

CDI in a module is represented by the corresponding CDI library in the module dependencies. You can download all the necessary library files right from within the IDE. You can also change the CDI version being used if and when needed.

Make sure that the CDI plugin is enabled

  1. In the Settings/Preferences dialog (Ctrl+Alt+S), select Plugins | Installed.

  2. Locate the Java EE: Contexts and Dependency Injection plugin in the list, and make sure that the checkbox next to it is selected. CDI plugin is enabled in the list of plugins
