 The workflow output `cache-hit` is set to indicate if an exact match was found for the key [as actions/cache does](https://github.com/actions/cache/tree/main#outputs).
 
-The workflow output `cache-primary-key` exposes the primary cache key computed by the action for the configured build tool. It is useful for composing with [`actions/cache`](https://github.com/actions/cache) or [`actions/cache/restore`](https://github.com/actions/cache/tree/main/restore) in later steps or dependent jobs that need to reuse the exact same key. It is empty when caching is not enabled or when caching is skipped (for example, when the cache service is unavailable).

 The cache input is optional, and caching is turned off by default.
 
 **Maven Wrapper:** when `cache: 'maven'` is enabled, the action also caches and restores the Maven Wrapper distribution downloaded to `~/.m2/wrapper/dists` (in addition to the local repository), so wrapper-based (`./mvnw`) builds don't re-download the wrapper on every run. This is keyed on `**/.mvn/wrapper/maven-wrapper.properties` as shown above.

 If your use-case requires a custom distribution or a version that is not provided by setup-java, you can download it manually and setup-java will take care of the installation and caching on the VM:
 
 > [!NOTE]
-> This approach also lets you use builds that setup-java does not provide directly, such as **Early Access (EA)** or other unreleased JDK builds (for example, an upcoming feature release or a Loom/Valhalla preview build). Download the desired archive in a prior step and point `jdk-file` at it; setup-java will extract, install, and cache it just like a supported distribution. When targeting multiple architectures, select the correct binary per architecture in your workflow (for example, with a build matrix).
