Language Plugins

Build, test, and compile plugins for major programming languages. Most auto-detect the project’s build tool or package manager, so a single plugin works across repos without per-project configuration. Each plugin pins one runtime version, baked into its shared base image at build time (single-version model) — there is no runtime version env var to set. Test runs emit standard reports (JUnit XML, coverage) where the toolchain supports them.

BUILD_TOOL selects Maven vs Gradle for the JVM plugins (auto-detected otherwise); MAVEN_GOAL/GRADLE_TASK override the lifecycle goal/task. PACKAGE_MANAGER pins npm/yarn/pnpm (Node) or pip/poetry/pipenv (Python) instead of auto-detecting. NATIVE_BUILD enables GraalVM native-image on java-oracle.

Runtime Versions

Each language plugin is a thin layer over a shared, single-version base image (for example pipeline-node-base, pipeline-go-base, pipeline-jvm-base), so the runtime version is pinned at image-build time — not selectable at runtime:

Language	Base image	Version pin
Java (Temurin, GraalVM)	pipeline-plugin-base	JDK + Maven/Gradle/Kotlin pinned in the plugin image
Java (Corretto)	pipeline-jvm-base	Amazon Corretto JDK + build tools baked in
Python	pipeline-python-base	One CPython version baked in
Node.js	pipeline-node-base	One Node + npm version baked in
Go	pipeline-go-base	One Go toolchain baked in
.NET	pipeline-dotnet-base	One .NET SDK baked in
Rust	pipeline-rust-base	One Rust toolchain (cargo/clippy/rustfmt) baked in
Ruby	pipeline-ruby-base	One Ruby + Bundler baked in
C/C++	pipeline-cpp-base	clang/GCC + CMake/Make/Meson/Conan baked in
PHP	pipeline-php-base	One PHP + Composer baked in

To move to a new runtime version, bump the pin in the base image and rebuild (see Version Management) — there is no per-pipeline version override.
