Jul 1, 2025July 2025 performance summary for gradle/gradle. Delivered key features and reliability improvements across IDE syncing, API integration, Kotlin testing, and cross‑platform stability, with a strong emphasis on test coverage and maintainability. Key outcomes include: Gradleception IDE sync tests and infra enhancements with a new IDE sync test, timeout bump, additional dependencies, explicit JDK location for the daemon, module openness for java.time, fixture leniency, and a JPMS arg comment. Degradation API integration updates to CCPromoHandler leveraging the new CC degradation API, plus minor polishing and suppression of deprecations during degradations collection. Kotlin testing enhancements adding coverage and polish for ConfigurationCache Kotlin types integration tests. Windows reliability hardening with legacy locking, immutable workspace execution, unscoped cache builder usage, and Windows‑specific tests for artifact transform workspace cleanup, all contributing to reproducibility. Serialization code-path coverage improvements and state preservation by keeping a nacked field and a provider in the task state to prevent loss of state across tasks. Overall impact: increased reliability, faster feedback, and cross‑platform consistency, enabling safer releases and more productive developer workflows.

Jun 1, 2025June 2025 monthly summary for gradle/gradle: Delivered major enhancements to the Configuration Cache Degradation workflow, including a dedicated ConfigurationCacheDegradationController service and its integration with ConfigurationCacheProblems, resulting in a centralized, auditable degradation workflow. Improved UX and observability by excluding degradation problems from console output, minimizing console noise, and always printing the CC report link in degradation mode. Refactored degradation state management to ConfigurationTimeBarrier for simpler, thread-safe logic. Expanded test coverage and readiness with buildSrc integration tests, CCGDIntegrationTest polish, and new tests for degradation in the presence of incompatible tasks and IP-enabled scenarios, plus model fetching tests. Fixed key stability bugs: surfaced user code exceptions during degradation evaluation, deduplicated degradationDecision access, and used Collections.unmodifiableMap in DCCDController. These changes collectively reduce build noise, improve reliability, and accelerate diagnosis of degradation-related issues, underpinning faster delivery of robust Gradle performance improvements.
