Sep 1, 2025September 2025: Focused on stabilizing backward compatibility for Hilt with older Dagger configurations and aligning tooling with newer Dagger releases. Implemented key fixes to support legacy setups by adding default values for AggregatedRoot and Aggregator and addressing missing rootComponentNames/rootComponentPackage, plus a follow-up to ensure internal Hilt metadata defaults preserve backwards compatibility. Also upgraded Dagger to 2.57.2 and updated docs/build scripts to reflect the latest version. These efforts reduce upgrade risk for users on legacy configurations and improve reliability and onboarding for new projects.

Mar 1, 2025Monthly performance summary for 2025-03 (google/dagger): Key features delivered include cross-package compatibility and codebase modernization that positions the project for broader Java/Jakarta interoperability and faster feature cycles. Major commits reflect a move toward a more modular, maintainable codebase and a modernized build system (Bazel-based) across multiple modules. Key features/achievements: - Hilt annotation processing compatibility across javax and jakarta: extends @Inject recognition to both packages, enabling compatibility across Java versions and dependency injection configurations. Commit: 9001b5503ac36ad0d7e76a8d89c6801a3ff4ce42. - Internal codebase restructuring and build system modernization across Hilt modules: consolidates and restructures core modules (hilt-core, dagger-*) and related build configurations to improve modularity and maintainability; updates span hilt-core, dagger-android, dagger-producers, Hilt-Android, dagger-grpc-server, hilt-android-testing, and Bazel compatibility. Commits include: 58d49ad0663225ebcaa2e5571d3e6261acf7cc9c, d53bfd7368dd1e4e7cf305fe749f15fb94ad7002, 123540efab893a4c8b0e0a80f1f163ff8d492c0d, a023758512f549a4888510c9c93972dcf4276745, 3aa1553a30b77d9d4041b9434e9e55290313ec6d, 98521084ac27c7befda199977ecea103d9832c55, c6e37c08345040a400231e6c6086c2de61b7ebdc. - Maintainability and future readiness: standardized restructuring and build configurations position the project for faster onboarding and easier cross-module changes, with an emphasis on Bazel compatibility. Major bugs fixed: No explicit bugs documented in this month. The work focused on compatibility enhancements and long-term maintainability rather than isolated bug fixes. Overall impact and accomplishments: - Broadened Java/Jakarta compatibility for dependency injection annotations, reducing integration friction for users migrating to Jakarta. - Streamlined, modularized codebase and modernized build system across the dagger ecosystem, enabling faster feature delivery and easier maintenance. - Strengthened foundation for future features (e.g., improved cross-module consistency and Bazel-based workflows). Technologies/skills demonstrated: - Java/Jakarta javax/jakarta annotations, annotation processing, and DI (Hilt/Dagger) - Large-scale codebase refactoring and modularization - Build system modernization and Bazel compatibility - Cross-module coordination and release readiness for enterprise adoption

Dec 1, 2024December 2024 monthly summary for google/dagger focused on cross-provider compatibility to reduce upgrade risk and enable Jakarta EE integration. Key work delivered includes expanding Dagger-generated factories with a create method that accepts dagger.internal.Provider to align with existing components, and extending compatibility to jakarta.inject.Provider by updating internal type definitions and request-handling logic. These changes preserve javax.inject.Provider usage during a transitional period to prevent breaking links across Dagger versions while enabling Jakarta (jakarta.inject.Provider) support. Result is smoother upgrades, broader ecosystem compatibility, and clearer migration paths for enterprise deployments.
