Take build.gradle.kts

tasks.withType(Test::class.java) {
    enabled = false
}

and you write a detector:

class WithTypeWithoutConfigureEachUsageDetector : Detector(), GradleScanner {
    override fun getApplicableMethodNames(): List<String> = listOf("withType")

    override fun checkMethodCall(
        context: GradleContext,
        statement: String,
        parent: String?,
        parentParent: String?,
        namedArguments: Map<String, String>,
        unnamedArguments: List<String>,
        cookie: Any,
    ) {

parent and parentParent are passed in as null.

Looking at the debugger, it seems that UastGradleVisitor.getSurroundingNamedBlock should also consider KotlinUQualifiedReferenceExpression (or more generic version UReferenceExpression) and use that to determine the parent.
