Android构建警告将新ns映射到旧ns

Question

我在 android studio 中创建了一个新项目并添加了所有依赖项。它们都是最新的。当我构建项目时，我收到了这些警告。应用程序中没有代码。这些在我添加依赖项后开始显示。
我应该就这样离开吗？

该应用程序运行没有任何问题，但因为这是我第一次看到的警告。我在其他任何地方都找不到任何相关的东西，想知道为什么会这样。

我遇到了同样的问题，结果发现 buildToolsVersion "30.0.3" used 没有安装，所以我切换到已安装的buildToolsVersion "29.0.3" (在我的情况下)并且警告消失了。
