lombok.config was ignored in Java builds (e.g. lombok.accessors.chain=true produced void setters), and jdt.ls wrote those classes into target/classes, breaking later Maven builds. Root cause: Lombok calls getModuleClassLoader(boolean), which newer Equinox removed; the exception is swallowed, Lombok resolves the wrong source path and finds no lombok.config at all, so every config key falls back to its default. Affects every Java project using lombok.config. Fix: ship Lombok 1.18.48 with the upstream fix projectlombok/lombok#4059 (lombok-1.18.48-openidea.1, embedded in the app, no download) as the jdt.ls agent; the versioned path also resets the jdt.ls workspace so stale output is rebuilt. A user-configured agent still takes precedence. Return to Maven Central once an official release includes the fix (source and checksum in plugins/lombok/README.md). Verified on macOS: 5 clean builds with chained setters, identical output to official 1.18.48 without lombok.config, the app rebuilds already-poisoned target/classes, and Run works. Windows and Linux not run. Fixes #565
The IDE you know, rebuilt in Rust.

OpenIDEA brings the IntelliJ IDEA way of working — its keymap, its tool windows, its search-everything habits — to a native app with a Rust core.
Editor, code insight, debugger, Git, terminal, database and HTTP clients, for 60+ languages. Builds for macOS, Windows and Linux.
Benchmark
Opening freqtrade (Python, ~770 files) with warm caches, median of 5 runs:
| OpenIDEA | IntelliJ IDEA 2026.2.3 | |
|---|---|---|
| Window with the project | 0.9 s | 3.1 s |
| Ready (CPU settled) | 1.1 s | 13.2 s |
| Memory (USS, all processes) | 169 MB | 2011 MB |
| CPU time until ready | 2.4 s | 47.9 s |
| Idle CPU | 4 % of a core | 7 % of a core |
| Quit | 0.3 s | 5.9 s |
A release build of OpenIDEA from main and IDEA with default settings and plugins, on
Windows 11, 32-core AMD, 62 GB RAM.
IDEA analyses Python more deeply, so "ready" doesn't mean the same work on
both sides. Both are measured from the outside, the same way: see
perf/compare to run it on your machine and projects.
Build
pnpm install
pnpm tauri dev
Rust 1.96, Node 22, pnpm and the Tauri prerequisites.
Native notebook execution tests are opt-in and need two distinct Python environments
with ipykernel installed:
OPENIDEA_TEST_PYTHON=/first/env/bin/python \
OPENIDEA_TEST_PYTHON_SECOND=/second/env/bin/python \
cargo test -p ide-notebook --test kernel_runtime -- --ignored --test-threads=1
