 - Gradle use `gradlew` wrapper
 
 NOTE: This example shows the usage of Spock 2.0, which uses the JUnit Platform. If you want to see how to get Spock 1.x with JUnit 4 up and running see the https://github.com/spockframework/spock-example/tree/spock-1.x[Spock-1.x] Branch.
 
+NOTE: Spock supports Java 8, but Groovy 5.0 requires Java 11+ and Gradle 9+ requires Java 17+.
+      So for simplicity’s sake the example uses Java 17.
+      If you want to use an older Java version, please use an older Gradle version (e.g. Gradle 8.x for Java 8+).
+     Check the https://github.com/spockframework/spock-example/tree/java-8[Java-8] Branch for the last state of the example with Java 8.
