  • {@link org.apache.maven.api.cache.CacheMetadata} - Configuration for cache behavior and lifecycle

    + *
  • PERSISTENT - Data persists across Maven invocations
    • + *
  • SESSION_SCOPED - Data retained for the duration of a Maven session

  • REQUEST_SCOPED - Data retained only for the current build request
    • + *
  • DISABLED - No caching performed

+ * RequestCache cache = cacheFactory.createCache();
+ * Result result = cache.request(myRequest, req -> {
+ *     // Expensive operation to compute result
+ *     return computedResult;
+ * });
