Comment for ServicePurgeTest.groovy (a GroovyScriptTestCase) fails

Using the commented line in ServicePurgeTest.groovy on Windows

./gradlew 'ofbiz -t component=service -t suitename=servicetests -t case=service-purge-test' --debug-jvm

I got this error:

Watching the file system is not supported

I did not check the syntax, but rather used

"ofbiz --test component=service --test suitename=servicetests --test case=service-purge-test"
