Junie Is Now Available in CLion (blog.jetbrains.com)

JetBrains’ AI coding agent Junie is now available inside CLion starting with version 2025.2.1 (Beta), bringing project-aware AI assistance directly to C and C++ workflows — especially valuable for embedded and performance‑critical development. Rather than hunting through build logs or reverse‑engineering target configs, developers can ask Junie about modules, execution paths, and project setup or have it generate documentation and READMEs. The integration centralizes common tasks — test generation, bug fixes, behavioral specs, and code reviews — so you can stay inside the IDE while getting actionable insights and automated edits. Junie works in two modes: Ask mode for Q&A and exploration, and Code mode for making edits, generating tests (GoogleTest, Catch2, CppUnit), running them, and producing change reports with rollback and Diff Viewer links. It leverages CLion tools (Search Everywhere, file structure, code analysis) to understand context, and offers a Brave mode for autonomous execution plus project guidelines via .junie/guidelines.md. Current Beta limitations include weak support for remote/WSL toolchains and a focus on CMake projects (other project types may need manual model reload). Installation is available through the JetBrains AI widget, the IDE Marketplace, or from disk. For C/C++ and embedded engineers, this promises faster iteration, more reliable tests, and less manual configuration work — with more polish expected in future releases.
