As mentioned in that blog post, this is part of a bigger initiative: moving our JVM intelligence to wherever our users are, no matter what editor or agent they are using.<\/p>\n<p>Today, we\u2019re proud to announce <strong>1.0<\/strong>, the first stable release of <strong>Java and Kotlin by IntelliJ IDEA.<\/strong><\/p>\n<p>And we\u2019re not shipping it alone. This release is also the result of a close collaboration with the team at <strong>Cursor<\/strong>, who have worked alongside us to make Java and Kotlin a first-class experience in their development environment.&nbsp;<\/p>\n<figure>\n<\/figure>\n<p><a href=\"https:\/\/marketplace.visualstudio.com\/items?itemName=JetBrains.intellij-server\" target=\"_blank\" rel=\"noopener\"><strong>Get <\/strong><strong><em>Java and Kotlin by IntelliJ IDEA<\/em><\/strong><strong> from Visual Studio Marketplace<\/strong><\/a><\/p>\n<p><a href=\"https:\/\/open-vsx.org\/extension\/JetBrains\/intellij-server\" target=\"_blank\" rel=\"noopener\"><strong>Get <\/strong><strong><em>Java and Kotlin by IntelliJ IDEA<\/em><\/strong><strong> from Open VSX Registry<\/strong><\/a><\/p>\n<h2>Why this matters<\/h2>\n<p>Agentic development is changing how software gets built. As agents take on more implementation work, developers spend less time manually editing code \u2013 and when they do edit, they often need only a focused set of features: navigating to declarations, finding references, code completion, and renames.<\/p>\n<p>These capabilities are exactly what the <a href=\"https:\/\/en.wikipedia.org\/wiki\/Language_Server_Protocol\" target=\"_blank\" rel=\"noopener\">Language Server Protocol<\/a> was built for: implementing language support once, and reusing it in any LSP-capable editor. And it\u2019s not only humans who benefit. Agents can call into an LSP directly, producing faster, more deterministic results \u2013 and, importantly, consuming fewer tokens.<\/p>\n<p>These are the workflows we want to accommodate with our extension and the underlying IntelliJ IDEA\u2019s Language Server and Debug Adapter.<\/p>\n<h2>Cursor collaboration<\/h2>\n<p>When we set out to bring IntelliJ IDEA\u2019s language intelligence beyond our own IDE, Cursor was a natural first partner.&nbsp;<\/p>\n<p>Their team collaborated closely with us throughout the development of the extension, battle-testing it and making sure Java and Kotlin developers get a seamless experience inside Cursor from the moment they open a project.&nbsp;<\/p>\n<blockquote>\n<p><strong><em>We\u2019re glad to work with JetBrains to bring Java and Kotlin language intelligence to Cursor. With Java and Kotlin by IntelliJ IDEA, developers get IntelliJ IDEA\u2019s code analysis, navigation, and refactoring while they work with Cursor\u2019s agents.<\/em><\/strong><\/p>\n<p><strong><em>\u2014 Rohan Shah, Product, SpaceX AI<\/em><\/strong><\/p>\n<\/blockquote>\n<h2>What\u2019s in 1.0<\/h2>\n<p><strong>Java and Kotlin by IntelliJ IDEA<\/strong> is powered by the same Java and Kotlin language technology as the IntelliJ IDEA desktop IDE. 1.0 brings a focused set of capabilities to VS Code and Cursor, including:<\/p>\n<ul>\n<li>Java, Kotlin, and mixed-language project support<\/li>\n<li>Smart code completion, navigation, and code analysis<\/li>\n<li>Refactorings and editor assistance<\/li>\n<li>Maven, Gradle, and Bazel build tool support<\/li>\n<li>Fast, reliable performance even on large projects and monorepos<\/li>\n<li>Support for test runners right now for JUnit<\/li>\n<li>Powerful debugging capabilities, including emulated breakpoints and async stack traces<\/li>\n<\/ul>\n<p>The full feature list is in our <a href=\"https:\/\/www.jetbrains.com\/help\/intellij-vscode\/About-instance.html\" target=\"_blank\" rel=\"noopener\">documentation<\/a>.<\/p>\n<p>For Cursor, there is dedicated support for the <em>Agents<\/em> <em>Window<\/em>.

The extension analyzes your project, imports it based on any Maven, Gradle, or Bazel build files it finds, and enables Java and Kotlin language features in the editor.<\/p>\n<h2>Compatibility notice<\/h2>\n<p>Java and Kotlin by IntelliJ IDEA includes code analysis and quick-fixes that overlap with Red Hat\u2019s and Oracle\u2019s Java extensions. To avoid duplicated or conflicting behavior, we recommend disabling those extensions while using ours.<\/p>\n<p>We have, however, made sure that our extension works well with others, like <a href=\"https:\/\/marketplace.visualstudio.com\/items?itemName=vmware.vscode-spring-boot\" target=\"_blank\" rel=\"noopener\">Spring Tools from the Spring Team<\/a>.<\/p>\n<h2>Licensing<\/h2>\n<p>With version 1.0, the extension moves out of its free preview phase. Using it now requires an <strong>IntelliJ IDEA Ultimate subscription<\/strong> after a 30-day trial period during which you can try out its full feature set for free.<\/p>\n<p>The same license covers IntelliJ IDEA\u2019s Java and Kotlin capabilities everywhere you work \u2013 the IntelliJ IDEA desktop IDE, VS Code-based editors like Cursor, and other supported environments. You can review pricing <a href=\"https:\/\/www.jetbrains.com\/idea\/buy\/?section=commercial&amp;billing=yearly\" target=\"_blank\" rel=\"noopener\">here<\/a>.<\/p>\n<p><strong>Note:<\/strong> <strong>The license is explicitly designed for human use; we\u2019ll release an update regarding licensing models for purely agentic use soon.<\/strong><\/p>\n<h2>Coming next: Agentic and terminal-based workflows<\/h2>\n<p><strong>Java and Kotlin by IntelliJ IDEA<\/strong> <strong>1.0<\/strong> in the editor is just one milestone.&nbsp;<\/p>\n<p>In one of the next releases, agents that you orchestrate in the <em>Agents<\/em> view in Cursor or VS Code will also be able to call the LSP directly when writing code, leading to faster, better, or cheaper results.<\/p>\n<p>In parallel, we\u2019ve been running experiments applying the same LSP- and DAP-backed intelligence to fully agentic, terminal-based workflows \u2013 think Claude Code or Codex calling directly into IntelliJ IDEA\u2019s Java and Kotlin understanding. News on this will also be announced soon.<\/p>\n<h2>Feedback and support<\/h2>\n<p>We\u2019re still listening \u2013 Java and Kotlin by IntelliJ IDEA 1.0 is a milestone, not the finish line.
