Native support for Maven Build Cache

New build system is joining BuildFetch Cache Club — this time it's Apache Maven with native support for the Apache Maven Build Cache Extension and its shared Remote Cache.

Maven Build Cache is free for Open Source projects.

JetBrains' State of Java 2025 with over 5,000 Java developer responses reports Maven as the most widely used Java build system at 67%.

Maven has been a foundation of the Java ecosystem for more than two decades and is used to build some of the world's best-known open-source JVM projects:

• Apache Software Foundation: Spark, Flink, Hadoop
• Netty: Netty
• Jenkins: Jenkins
• Google: Guava
• Quarkus: Quarkus
• Keycloak: Keycloak
• Trino: Trino
• FasterXML: Jackson Databind

Simply set BuildFetch URL and token in Maven configuration and instantly get much faster builds!

See Configure Maven Build Cache for the short setup.

Technical Extravaganza

The Apache Maven Build Cache Extension is an opt-in caching engine for Maven 3.9+ and Maven 4. It derives cache keys from build inputs such as source files, dependencies, the effective POM, plugin configuration and other configured inputs, then restores matching build outputs instead of repeating the work.

Maven effectively caches both compilation and test execution allowing to save up to 90% in time and cost on CI.

BuildFetch natively implements the Maven Build Cache HTTP protocol spec on top of our storage, authentication and metrics infrastructure.

Our end-to-end integration test suite now includes real Maven builds against BuildFetch Cache ensuring expected cache hits and metrics both on backend and Maven CLI side. This allows us to maintain long term compatibility with Maven Build Cache as our monorepo evolves.

Product Vision

Maven becomes the 9th build system publicly supported by BuildFetch Cache. The public lineup is Bazel, Gradle, Maven, Sbt, Ccache, Sccache, Go, Nx, and Turborepo.

Our Unified Cache Platform covers remote caching for Backend, Frontend, Mobile & AI / ML teams with a single Cloud subscription or On-prem deployment.

More build systems & new BuildFetch products are coming soon.

Best regards, BuildFetch Team.
