March 2026 monthly summary for apache/maven. Key feature delivered: Processor Path Type Preservation in Maven Dependency Resolution, implemented as a two-phase approach to ensure processor-dependent artifacts are correctly tracked on both module-path and processor-module-path. TypeCollector records transitive processor dependencies before conflict resolution, and TypeDeriver assigns processor types after ConflictResolver, enabling the DefaultDependencyResolverResult to include artifacts on both paths. Major bug fixed: a conflict-resolution bug where processor path types could be dropped, causing artifacts to appear only on the module-path. The fix preserves correct path inclusion across the resolution lifecycle. Overall impact: improved build accuracy and reliability in complex dependency graphs, reducing mis-resolutions and downstream plugin issues (e.g., maven-compiler-plugin) with negligible cost to builds that have no processor-type direct dependencies due to short-circuit optimization. Technologies/skills demonstrated: dependency resolution architecture, conflict resolution flow, TypeCollector and TypeDeriver usage, processor path typing, maven-resolver extension points, Java tooling.
