2025-04 Monthly Summary: Focused on stabilizing Gradle-based builds and improving upgrade readiness. Key features delivered: Gradle 9 compatibility updates for the test-retry-gradle-plugin (removing deprecated test parameters, safe publishPlugins usage, explicit JUnit launcher dependency) and added a minimal passing test to cover scenarios with no tests; Develocity Gradle plugin upgraded from 4.0 to 4.0.1 across gradle/gradle to gain stability and bug fixes. Major bugs fixed: test-suite robustness improvements ensuring Gradle 9 runs tests even when none exist and fixes to functional/DSL tests for reliable execution. Overall impact: higher CI reliability, smoother Gradle 9 upgrade path for downstream users, and reduced maintenance burden. Technologies/skills demonstrated: Gradle tooling, plugin development, dependency management, test strategy, and refactoring to remove deprecated API usage.
