* fix(java): Run jdtls with a Lombok agent and show build errors at launch jdtls compiles with ECJ, which only generates Lombok members when the server JVM runs -javaagent:lombok.jar. Nothing put it there, so @Data / @Setter classes lost their accessors and Run launched stale classes with "Unresolved compilation problem" stubs and no explanation. - Projects whose build files mention Lombok get the newest jar: the IDE-managed one (new "Lombok (jdtls agent)" tool, latest release from Maven Central), else ~/.m2 (incl. settings.xml localRepository) or the Gradle cache. Each agent gets its own jdtls workspace so everything is rebuilt with it. - Settings › Languages & Frameworks › Java › JVM options (java.jdt.ls.vmargs); a Lombok agent there wins. - Run (and Debug, as a notification) list the first compile errors when the build has errors, plus a hint when Lombok is missing or older than 1.18.34. Fixes #3 * fix(java): Base the Lombok hint on the agent jdtls actually runs A Lombok agent in Settings › Java › JVM options wins over the managed and cached jars, but the launch hint still looked only at those: with no cached jar it said Lombok was missing, and with an old cached one it blamed that version although jdtls ran the user's. The hint and the startup warning now use the user's agent (version from its file name).

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.
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.
