jetbrains/intellij-community — reverse-engineered prompt

Build me a community desktop IDE for developers, basically a realistic starter version of IntelliJ IDEA Community.

I want users to be able to open a project folder, browse files, edit code in tabs, see syntax highlighting, search across the project, and run simple build or test commands from inside the app. Include a built in terminal panel, a problems panel for errors, and basic run configurations so someone can save and rerun commands. It should feel like a real coding workspace, not just a text editor.

Please make the core in Java and keep it organized so language support and tools can be added later like plugins. Don’t try to recreate every JetBrains feature, focus on a solid working MVP that opens, edits, saves, searches, and runs commands reliably.

Set up the project so I can build and launch it locally, with clear instructions. Look up current docs online if you need to.
