Gradle Build Cache is a tool designed to optimize build times by reusing outputs from previous builds, which can be stored locally or remotely. This functionality allows developers to avoid redundant processes and reduce the cost and time associated with regenerating build outputs. The cache can significantly speed up both local and continuous integration (CI) builds by sharing and reusing unchanged outputs across a team. Gradle's build cache supports both Gradle and Maven environments and can be configured to work with local and remote caches, enabling build outputs to be reused across different workspaces, branches, and users. This tutorial outlines the steps for enabling and configuring the build cache, including setting up the necessary plugins and cache directories. It also covers how to verify that caching is working correctly by using build scans, and how to optimize the setup for CI environments. The document emphasizes the benefits of using the build cache to improve build performance and developer efficiency.
