* There should not be setters for lazy properties like link:{javadocPath}/org/gradle/api/file/ConfigurableFileCollection.html[`ConfigurableFileCollection`].  Use `setFrom` instead. For example,
----
    validateTaskProperties.getClasses().setFrom(fileCollection)
    validateTaskProperties.getClasspath().setFrom(fileCollection)
