google/guava

This system is a comprehensive utility library that provides a wide range of core Java functionality, including collections, caching, hashing, and concurrency utilities. It is specifically adapted for multiple platforms, offering Android-compatible implementations of Guava's features alongside GWT (Google Web Toolkit) and J2CL (Java to JavaScript) compatible versions. The library also includes a testing framework (guava-testlib) to validate collection and utility behavior across these different environments.

This period focused on modernizing Guava's core APIs, notably introducing the CacheBuilder and Source/Sink abstractions while adding GWT and Android build support. The team also expanded the library with new utilities for escaping, hashing, and math, alongside significant improvements to the testing framework.

This period focused on porting Guava's core utilities to the Android platform, introducing a parallel build that includes collections, caching, and concurrency utilities optimized for that environment. Concurrently, the project expanded GWT compatibility by providing GWT-specific implementations and test platforms to ensure the library functions correctly in browser-based Java environments.

This period focused on modernizing the project's build infrastructure and module structure, including updates to Gradle and Maven wrappers and the introduction of Java Platform Module System (JPMS) descriptors. Additionally, the codebase was refactored to support independent versioning of the ListenableFuture API and improved compatibility with web compilation tools like J2CL and ProGuard.
