 ### Caching packages dependencies
 The action has a built-in functionality for caching and restoring dependencies. It uses [actions/cache](https://github.com/actions/cache) under hood for caching dependencies but requires less configuration settings. Supported package managers are gradle and maven. The format of the used cache key is `setup-java-${{ platform }}-${{ packageManager }}-${{ fileHash }}`, where the hash is based on the following files:
-- gradle: `**/*.gradle*`, `**/gradle-wrapper.properties`
+- gradle: `**/*.gradle*`, `**/gradle-wrapper.properties`, `buildSrc/**/*.kt`
 - maven: `**/pom.xml`
 
 The cache input is optional, and caching is turned off by default.
