linguo jvm manages Eclipse Temurin JDKs from the Adoptium API (per-platform tarballs with inline sha256s, including native alpine-linux musl builds; macOS Contents/Home nesting handled; install and upgrade --latest default to the newest LTS). Pins fall back to .java-version, and run/which/the shell hook wire JAVA_HOME, which the hook now exports on entry and unsets on leave. Kotlin, Groovy, and Scala are runtime-only JVM languages sharing one engine (jvmlang): Kotlin compiler zips from JetBrains releases and Scala 3 tarballs verified against GitHub asset digests, Apache Groovy zips against Apache's .sha256 sidecars. Each language resolves its JDK through a per-language [jvm] binding written by `linguo <lang> set-jvm <version>` (project linguo.toml or --global), falling back to the directory's plain jvm pin, so mixed-JDK setups work per language. Alpine and Windows CI smoke tests cover the jvm and groovy flows. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Toolchains like groovy and kotlin ship an extensionless unix launcher next to the .bat; find_in_dir preferred the exact name, handing CreateProcess a shell script (error 193). On Windows only .exe/.cmd/ .bat/.com count, extension search order otherwise. Also restores a quote my earlier edit dropped in the Alpine groovy smoke line.

Batch launchers validate JAVA_HOME with `if exist`, which rejects the mixed-separator paths that leak in when $LINGUO_ROOT is set with forward slashes (e.g. Git Bash). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Temurin JDK management via the Adoptium API (jvm language key, JAVA_HOME wiring incl. hook lifecycle), plus Kotlin/Groovy/Scala as runtime-only JVM languages with per-language set-jvm bindings falling back to the jvm pin. Alpine + Windows smoke coverage.
