Consumer POM: keep only transitive dependencies; drop non-transitive scopes (original) (raw)

Context:
Maven 4 introduces refined dependency scopes and a consumer POM generator that attempts to create a Maven 3-consumable POM. We need to align consumer POM generation with scope transitivity semantics.

Proposal:

• When generating the consumer POM for non-POM artifacts, keep only dependencies whose scopes are transitive according to org.apache.maven.api.DependencyScope#isTransitive (default/null scope treated as COMPILE).
• Drop non-transitive scopes (e.g., compile-only, test-only, provided, system, none, import, test, etc.).
• This replaces the previous special-case mapping logic and simplifies behavior: consumer POM expresses only transitive dependencies.
