File contents

Build System

Quarkus uses Maven. The full build is large; know how to build selectively. Ensure MAVEN_OPTS includes at least -Xmx4g for builds (do not override the user's existing MAVEN_OPTS).

Quick Build (First Time)

./mvnw -Dquickly

This skips tests, ITs, docs, native, and validation.

Building a Specific Extension

# All modules of an extension
./mvnw install -f extensions/<name>/

# A single module
./mvnw install -f extensions/<name>/deployment

Building Core

./mvnw install -f core/ -DskipTests

Running Tests

# Run tests for an extension
./mvnw verify -f extensions/<name>/ -Dstart-containers -Dtest-containers

# Run a single test class
./mvnw test -f integration-tests/<name>/ -Dstart-containers -Dtest-containers -Dtest=MyTest

# Run a single test method
./mvnw verify -Dstart-containers -Dtest-containers -Dtest=fully.qualified.ClassName#methodName

# Native integration tests
./mvnw verify -f integration-tests/<name>/ -Dstart-containers -Dtest-containers -Dnative

Incremental Build

# Build only changed modules and their downstream dependencies
./mvnw install -Dincremental

Key Maven Flags

Flag	Purpose
`-Dquickly`	Skip tests, ITs, docs, native, validation
`-DquicklyDocs`	Like `-Dquickly` but includes docs
`-Dnative`	Build and test native image
`-Dno-format`	Skip code formatting check
`-DskipTests` / `-DskipITs`	Skip unit / integration tests
`-Dno-test-modules`	Skip building test modules
`-Dincremental`	Only build changed modules

Justfile

A justfile (.justfile in the repo root) provides convenience aliases. Run just -l to see them. By default uses ./mvnw -T0.8C (parallel build). Set QMVNCMD to override the Maven command (e.g., QMVNCMD=mvnd for Maven Daemon).

Important Build Rules

Always install (not just compile) when building modules that other modules depend on
If you change a runtime module, rebuild its deployment module too
If you change something in core/, downstream extensions may need rebuilding
Use ./mvnw (the wrapper) to ensure the correct Maven version
After adding/removing/renaming an extension, run update-extension-dependencies.sh
