Last week, we shared our point of view on where we think agentic development is headed and introduced JetBrains’ answer to it: JetBrains Air, an open system of products for agentic development. Today, we’re launching the Early Access Program for Air in JetBrains IDEs. It’s available now as a plugin on JetBrains Marketplace or natively […]
AI can produce code. Organizations still have to produce software. Agentic development is changing how software gets made, but it hasn’t changed what it costs to be wrong. Six months ago, we began publicly experimenting with agentic development environments. Around the same time, we introduced JetBrains Central as an open control and execution system for […]
Modern development tools, especially IntelliJ IDEA, have such comprehensive debugging support that for virtually any niche use case, there is a specialized tool for the job. This can make it hard to know where to begin. If you are new to debugging tools and want the biggest return on your learning investment, the best feature […]

In line with the six-month release cadence, Java 27 was released on September 15, 2026. In this blog post, we will look at what’s included in this release, how IntelliJ IDEA continues to support the latest Java versions, and even how IntelliJ IDEA is benefiting from some of the changes to the JDK. Java 27 […]
JetBrains IDEs have worked with WSL for many years, and over time, several ways of using it have emerged across our products. Depending on the entry point, the IDE could rely on a different underlying architecture, leading to a different experience. Starting with the 2026.2 release, there is one recommended entry point. In IntelliJ IDEA, […]
You set a breakpoint inside a Spring MVC controller, or a service, send the request to an HTTP endpoint, and nothing happens. The response is back – and it is a 403 (or 401, or a redirect to a login page). At that point, the bug you were trying to catch is no longer the […]

The Grails plugin for IntelliJ IDEA (which provides framework-aware coding assistance, GSP tooling, and GORM integration) has moved to the Apache Grails project. The Apache Software Foundation (ASF), which already stewards the Grails framework, now owns the plugin’s source code, which lives in its new GitHub repository. On JetBrains Marketplace, the plugin is listed as […]
Java concurrency is a powerful feature, but it can be difficult to get right. Writing correct multithreaded code requires a deep understanding of thread pools, synchronization, cancellation, and error propagation. Even experienced developers regularly introduce subtle bugs like thread leaks, swallowed exceptions, and race conditions that only surface under specific circumstances. Traditionally, Ja…
Spring Boot provides comprehensive externalized application configuration support. It enables one application artifact to run in different environments by supplying values from various sources such as: In this article, we’ll explore the best practices for managing Spring Boot application configuration. A well-designed configuration strategy should ensure that: Configuration properties classificati…
The Agent Client Protocol (ACP) defines a common contract between a client – like IntelliJ IDEA – and an agent. IntelliJ IDEA already includes several ACP-compatible agents: Codex, Claude Agent, and Junie. Beyond these bundled options, the ACP Registry provides more choices, and teams can register internal or unlisted agents through acp.json. The key idea […]
When developers hear “AI in the IDE”, the first thing that often comes to mind is a chat window. IntelliJ IDEA includes an AI chat, but JetBrains AI features also appear in many other parts of the development workflow. Some of those features are easy to miss because they are built into existing IDE actions: […]
Agent Skills have become a key building block of the Agent Harness for AI-driven agentic development. They give AI agents additional capabilities and knowledge, enabling them to complete tasks in a way that aligns with your preferences. If you are new to Agent Skills, I recommend reading AI-Assisted Java Application Development with Agent Skills first. […]

The simplest tools are often the most useful, and debugging is a prime example of this. There are many advanced debugging techniques, and while they all have their use cases, println debugging is still the #1 choice, whether you’re doing it manually or with the help of coding agents. Inserting a println statement to inspect […]
July gave the tech world plenty to talk about, from fresh releases and useful tutorials to Kotlin updates, AI experiments, and new ideas across the wider ecosystem. We packed the best of it into one issue, so you can skip scrolling and get straight to the good stuff. To top it all off, Donald Raab […]
It’s no secret that agentic development is changing how developers build software. As agents take on more and more of the implementation work, developers spend less and less time manually editing code. For this manual work, they might only need a basic, narrow set of features that IDEs provide, like navigating to declarations, finding references, […]
Reverse Engineering in the context of database-driven application development means generating Java persistence artifacts such as entity classes and mapping files from an existing database schema. This is useful when the database already exists, especially in legacy systems or large projects where creating entity classes manually can be slow and error-prone. Until now, these features […]

Starting from IntelliJ IDEA 2026.2, JetBrains will sunset Kotlin Notebook as a product and will no longer maintain it. The plugin will remain available on an open-source model so the community can continue its development. Below, we explain why we’re making this change, how it affects current Kotlin Notebook users, what comes next, and how […]
Language Server Protocol (LSP) solves a real problem: before, each IDE or editor had to implement support for a specific language separately. A language server puts that work in one place and exposes it through a common protocol, providing completion, formatting, documentation, and related features. That common protocol is only a part of the IDE […]
Every developer has tools they rely on daily. The workflows they’ve built around them, the ways they’ve learned to move faster, debug smarter, and write better code – that kind of hands-on experience can be hard to put into words. We’re collaborating with LinkedIn to make it easier for you to showcase your expertise with […]
