android - 如何解决自定义 Lint 规则中context.report的重载分辨率歧义？

Question

今天，我开始学习如何制作一些基本的lint规则，尝试为变量创建lint规则，以检查其名称的长度。

@Suppress("UnstableApiUsage")
class VariableLengthDetector : Detector(), Detector.UastScanner {

override fun getApplicableUastTypes() = listOf(UVariable::class.java)

override fun createUastHandler(context: JavaContext) =
    VariableLengthHandler(context)


class VariableLengthHandler(private val context: JavaContext) :
    UElementHandler() {

    private val variableMinimumLength = 3

    override fun visitVariable(node: UVariable) {

        node.name?.let {
            if (it.length < variableMinimumLength) {
                context.report(
                    issue = variableLengthIssue,
                    scope = node,
                    location = context.getNameLocation(node),
                    message = "this variable can be better named"
                )
            }
        }
    }
}

}
由于此处引起的过载歧义，该代码无法编译:

context.report(issue = variableLengthIssue,
               scope = node,
               location = context.getNameLocation(node),
               message = "this variable can be better named")

据我了解，这是因为context.report的重载可以是

public final fun report(issue: Issue, scope: PsiElement?,...

或者可以是

public final fun report(issue: Issue, scope: UElement?,...

但是我不确定如何使用我拥有的Uvariable元素定义这些元素？
我该如何解决这种过载歧义？

Answer 1

您可以将其转换为UElement。

context.report(
    issue = variableLengthIssue,
    scope = node as UElement,
    location = context.getNameLocation(node),
    message = "this variable can be better named"
)
