GSoC 2025 - Improving Configuration Cache and Lock Contention in Key Gradle Plugins#
This project aims to improve Gradle’s build performance by enhancing Configuration Cache support and reducing lock contention in widely-used plugins.The project will help analyze cache behavior and identify areas where multiple processes compete for shared resources, which can slow down builds.
The long-term goal is to improve developer productivity and CI reliability by making Gradle builds faster, more predictable, and easier to optimize—especially in large-scale projects.

Rationale#
Gradle builds often suffer from long execution times, especially in large or complex projects. The Configuration Cache is designed to solve this by avoiding repeated work during configuration, but many plugins are not fully optimized to support it. Similarly, lock contention in critical plugins creates bottlenecks that degrade performance during parallel execution.
This project focuses on identifying and addressing these two performance pain points:
- Improving cache usage insights
- Reducing lock contention
By enhancing these mechanisms, the project supports more scalable and efficient builds, benefiting the broader Gradle ecosystem.
