 WARNING: Note the `fetch-depth: 0` option on the `Checkout` workflow step. It is required for JReleaser to work properly.
 Without that, JReleaser might fail or behave incorrectly.
 
-The last step executes a `full-release` with the default `jreleaser.yml` configuration that's expected
-to be located at the root of the repository.

-IMPORTANT: This action requires Java 11+ to download and execute JReleaser. If your project already builds with Java 11+
