Jan 1, 2025January 2025 (apache/lucene): Delivered targeted build optimization and stability improvements. Implemented Gradle JVM ReservedCodeCacheSize tuning to enhance compilation performance, followed by a memory-conscious adjustment to optimize usage. Reverted Gradle Enterprise build scans publishing and updated environment configurations and plugin usage, including a refreshed README badge. Implemented gating to skip dataset-related tasks for external data no longer available at home.apache.org, preventing spurious build/test failures. These changes reduced build noise, strengthened CI reliability, and preserved performance gains, enabling faster iterations and more deterministic releases.
