…ove deps handling This commit introduces significant improvements to how native modules and dependencies are handled within the JetBrains plugin. Key changes include: - **Architecture-specific native module loading**: The `genPlatform.gradle` script has been updated to support different architectures (arm64, x64) for native `.node` modules. It now creates architecture-specific directories and generates a JavaScript loader to dynamically select the correct native module at runtime based on the OS and architecture. This ensures compatibility across various macOS, Windows, and Linux environments. - **Enhanced dependency checking**: New `deps:check` scripts have been added to `jetbrains/host/package.json` and integrated into `turbo.json`. This ensures that the VS Code submodule is initialized and up-to-date before patching or copying dependencies, preventing issues with missing files. - **Streamlined dependency copying**: The `deps:copy` script now includes `mkdir -p` to ensure the target directory exists before copying, improving robustness. - **Simplified `npm install` for resources**: The `copy:resource-nodemodules` script in `jetbrains/plugin/package.json` now uses `npm install` directly instead of `npm ci` and removes the `package-lock.json` copy, simplifying the resource bundling process. These changes improve the build reliability, cross-platform compatibility, and overall maintainability of the JetBrains plugin.

Migrates the `check-dependencies.sh` script to a cross-platform Node.js version (`check-dependencies.js`). This change improves compatibility across Windows, macOS, and Linux environments for the JetBrains plugin build process. Updates `package.json` to use the new Node.js script and bumps `glob` and `rimraf` dependencies. The shell script is retained but modified to call the new Node.js script and include retry logic for CI environments.

Adjust the CI pipeline to gracefully handle Java version discrepancies, particularly for JetBrains plugin builds. This update enables the `code-qa.yml` workflow to conditionally build the VSIX on Windows runners by excluding JetBrains components, acknowledging the platform's Java 17 limitations. Concurrently, the Java dependency check script now provides nuanced feedback in CI environments, issuing warnings for non-Java 17 versions on Linux/macOS and allowing continuation, while explicitly bypassing JetBrains plugin compilation on Windows CI where Java 17 is not guaranteed.

woof, what a monster PR! I left a bunch of comments, but let's meet up tomorrow and chat about things. Some of that kotlin code is absolutely wild, haha. Approving since all the changes in the extension are benign, but let's chat briefly and then merge tomorrow!

jetbrains/host/src/main.ts

+
+// Create ExtensionManager instance and register extension
+const extensionManager = new ExtensionManager()
+const rooCodeIdentifier = extensionManager.registerExtension("kilocode").identifier


roo - not sure if we want to rename all of these

jetbrains/host/src/rpcManager.ts

+// Promisify Node.js fs functions

+const fsWriteFile = promisify(fs.writeFile)
+const fsRename = promisify(fs.rename)
+const fsCopyFile = promisify(fs.copyFile)
+const fsUnlink = promisify(fs.unlink)
+const fsLstat = promisify(fs.lstat)
+const fsMkdir = promisify(fs.mkdir)


import { promises as fs } from "fs"
Could just use this?

lol but I get it

Interesting that we are keeping these in Kotlin! It'd think we'd want all prompt stuff to live in our core host and this would just delegate?

adamhill · 2025-09-04T02:27:20Z

@hassoncs I am convinced the plugin was heavily vibed by Copilot - when I looked at the branch list on GH back when I did my PR, there were dozens and dozens of copilot/xxxx branches in there.

But hey it works – we will just need lots of Kilo credits to work on it now.

Welcome to the new technical debt! :-P
