Apache Maven Build Cache Extension

This project provides a Build Cache Extension feature which calculates out-of-date modules in the build dependencies graph and improves build times by avoiding re-building unnecessary modules. Read cache guide for more details.

Requires Maven 3.9+ (MNG-7391).

Running Integration Tests

Test coverage, Testing approach

• Test plan
• Test projects

Full test suite

# Maven 3.9 (default)
mvn verify -Prun-its

# Maven 3.10
mvn verify -Prun-its,maven3.10

Maven 4 support is incoming (waits for 4.0.0-rc-6).

Smoke profile (quick developer check)

The run-its-smoke profile runs a focused subset of ~42 integration tests annotated with @Tag("smoke"). It covers the most critical cache behaviours plus at least one test per Maven project flavour (P01–P19) and per major cache trait (F1–F13). Typical runtime is significantly shorter than the full suite.

# Maven 3.9 (default)
mvn verify -Prun-its-smoke

# Maven 3.10
mvn verify -Prun-its-smoke,maven3.10

Tests are selected via the JUnit 5 tag smoke. To add a new test to the smoke profile, annotate its class with @Tag("smoke").
