IntelliJ IDEA 2026.2.1
JetBrains has released IntelliJ IDEA 2026.2.1 (build 262.9437.185), the first bug-fix update to the 2026.2 generation of its flagship Java IDE. The update, published August 10, 2026, addresses more than two dozen issues across build tooling, the debugger, and framework integrations without introducing new features.
What Changed
The headline fixes target the pain points reported since the 2026.2 release. Gradle users working inside WSL or Docker get a compatibility fix, Gradle 9.5.1 joins the compatibility matrix, and the "Run Anything" action no longer fails with a misleading "Unknown command-line option" when using --isolated-projects. Maven support now covers the 3.10.x line (currently RC-1).
Debugger and Java Fixes
- Method breakpoints work correctly in compact source files.
- Logpoints no longer attach to a lambda in a call chain instead of the intended line.
- Empty
println()statements are no longer replaced with logpoints. - Println navigation fixed for simple Gradle applications.
- "Optimize Imports on the Fly" no longer breaks Undo.
- Smart tabs settings are now respected during code formatting.
Framework and Server Updates
JBoss/WildFly debugging on WSL is fixed after the earlier JAVA_OPTS to JAVA_TOOL_OPTIONS migration, and the "Native management port configuration not found" error in run configurations is resolved. Flyway migration tooling received three fixes covering dropped and recreated bigdecimal fields, migrations not running, and naming strategy behavior. Groovy 5 array methods are now recognized during resolution, and the JSP plugin has been unbundled as part of JetBrains' ongoing platform cleanup.
Why It Matters
2026.2.1 is a stability release in the truest sense: no new UI, no new language features, just the fixes that make the 2026.2 line production-ready for teams that jumped in at launch. The Gradle and WSL fixes in particular will matter to anyone running builds in containers or remote filesystems.
What's Next
The update is available now through the Toolbox App, the in-IDE updater, or the JetBrains website. A full list of resolved issues is published in the official release notes on YouTrack.
