Key updates

  • IntelliJ IDEA 2023.2 introduces AI Assistant, which offers integrated AI chat and can do things like automatically write documentation comments for you, suggest names, generate commit messages, and more. Access to the AI capabilities is limited for now and requires you to install the AI Assistant plugin and log in to the JetBrains AI service. For more information refer to this blog post.

  • We’ve updated the Settings/Preferences | Plugins section, which now includes a set of suggested plugins that is determined automatically based on your project specifics.
  • We’ve reworked the UI for the running and debugging actions in the Services view to make the look and feel of the toolbar consistent with that of the main Run/Debug widget.
  • To make managing multiple run configurations easier, we’ve implemented the option to pin preferred configurations in the Run widget.


  • We have improved and expanded Java inspections to help you maintain high-quality code and detect potential issues more effectively. Learn more about the code analysis improvements in IntelliJ IDEA 2023.2 in this blog post.

  • IntelliJ IDEA 2023.2 features a new command line tool for quickly building and uploading shared indexes in just a few clicks instead of using multiple scripts and services. Learn more.


  • When debugging your reactive application, you can now easily evaluate values of watches and local variables for Mono and Flux types.
  • We have expanded the capabilities of the auto-testing functionality, making it fully compatible with the Maven, Gradle, and JPS build systems. 

Version control systems

Frameworks and technologies 

The following features and updates introduced to support working with frameworks and technologies are only available in IntelliJ IDEA Ultimate 2023.2.

  • As of IntelliJ IDEA 2023.2, it is possible to run and debug applications deployed to Tomcat on the Windows Subsystem for Linux (WSL).
  • You can now send gRPC requests over Transport Layer Security (TLS) in the HTTP Client.
  • The HTTP Client is capable of understanding Swagger and OpenAPI specifications and providing corresponding code completion options for JSON request bodies.

  • Spring configuration beans no longer require the annotation processor, and code completion and validation in properties and YAML configuration files are available right away.
  • IntelliJ IDEA 2023.2 provides support for Spring AOP in Kotlin.
  • Working with the AsyncAPI specification format is now much easier, as the IDE supports schema validation functionality and provides code completion for references, the Endpoints view, and the Editor Preview pane.

First, easy configuration allows you to trigger analysis with a few clicks, view project-wide problems, and set up quality gates in your preferred CI/CD system. Second, you can see the server-side analysis results without leaving your IDE. Learn more.

Database tools
