The JDK was always picked automatically (JAVA_HOME, PATH, the usual install dirs, by the
module's Java version) and Maven was the project's mvnw or mvn on PATH, with no way to
override either. languages.java.jdk (Languages & Frameworks › Java › Project JDK) now sets
the default jdtls runtime, the JDK of Run/Debug and JAVA_HOME for Maven and Gradle;
languages.java.maven (Build Tools › Maven) sets the Maven home, -s and
-Dmaven.repo.local for sync, builds, tool-window goals and detected run configurations.
JDKs and Maven installations are detected for the pickers.
Closes#13
* 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).
a66f01e adds files.ignoredNames to exclude_globs(), so the expected
length is file_excludes() + 1, not files.exclude + 1. The test failed on
every platform since.
* fix: Stop the status refresh loop and the double project open at startup
Every status rewrote .git/index, even with nothing to persist: gix's
`write_changes` writes an empty change set too. The watcher reports
.git/index writes as VCS changes, so each status triggered the next one,
together with an ahead/behind walk. On a repository with a long history
(freqtrade, 33k commits behind upstream) that kept a core busy for as long
as the project was open. Write back only when `has_changes()`.
A project passed on the command line was opened twice: the launch and the
"reopen last project" restore ran concurrently, and the restore checked
for an open project before the launch had finished. The second open found
the index cache locked and indexed in memory only; with a different last
project, the window ended up on whichever finished last. The restore now
waits for the startup launch.
* fix(lsp): Run jdtls on the Java version its bundles need
jdtls's launcher checks for Java 21, and so did JDTLS_MIN_JAVA, but the
Eclipse platform a release ships moves on: 1.63 bundles
org.eclipse.core.filesystem with JavaSE-25, so on a JDK 21 the server died
resolving its bundles ("jdtls is not ready (Crashed)") and the error told
users to install the 21 they already had.
Read the requirement from the installed jdtls instead: the highest osgi.ee
capability / Bundle-RequiredExecutionEnvironment among its plugins'
manifests (cached per install), never below 21. The runtime choice, the
rescan while no JDK fits and the "needs JDK N" message use it.
Fixes#4
* fix(lsp): Run jdtls on a JDK 21+ and offer Install in the server popup
jdtls refuses to start on Java < 21, and its launcher took whatever
JAVA_HOME / PATH pointed at, so it crash-looped with a Python traceback
when that was an older JDK (#1). Pick the first detected JDK 21+ and pass
it via JAVA_HOME; projects still compile against their own runtimes.
When none is found, report a clear message instead of launching, and
rescan on restart so a newly installed JDK is picked up. JDK detection
now also covers the java on PATH and Windows vendor directories.
The Language Servers status popup showed the manual install hint for
missing servers; it now has an Install button that runs tools.install,
which opens the Language Servers settings page for tools the IDE cannot
install itself.
Fixes#1

* fix(lsp): Address review of the jdtls runtime check
- Cache the JDK scan and rescan at most every 10s while no JDK 21+ is
found, refreshing the shared list instead of discarding it; skip
duplicate Windows Program Files roots.
- Check `launch_error` in the manager (inside the blocking launch task)
rather than in ProcessLauncher, and skip such servers in batch
inspection.
- Keep the install hint visible next to the Install button; when the tool
list failed to load, try the install so the error is reported.
- Don't let a server snapshot requested before a status event overwrite
that newer status (left jdtls showing "Starting…" while missing).
Use the Windows wrapper name for Maven, compare walked paths with `/`,
relax the own-process footprint floor, skip tests that assert Unix paths
or shells on Windows, and stop Git converting fixture line endings in CI.
