Description

For subprojects not containing Java sources, i.e. Groovy only we get warnings like:

> Task :groovy-groovysh:checkstyleMainReport
A problem was found with the configuration of task ':groovy-groovysh:checkstyleMainReport'. Registering invalid inputs and outputs via TaskInputs and TaskOutputs methods has been deprecated and is scheduled to be removed in Gradle 5.0.
 - File 'C:\Projects\groovy\subprojects\groovy-groovysh\target\reports\checkstyle\checkstyleMain.xml' specified for property '$2' does not exist.

We should add an appropriate guard or not apply plugin for this case.
