//    permits to start the build setting the javac release parameter, no parameter means build for java8:
// gradle clean build -x javaDoc -PjavacRelease=8
// gradle clean build -x javaDoc -PjavacRelease=17
//    also supported is to build first, with java17, then switch the java version, and run the test with java8:
// gradle clean build -x javaDoc -x test
// gradle test
val javacRelease = (project.findProperty("javacRelease") ?: "8") as String
