我正在尝试在架构组件中安装最新版本的导航。我正在关注此文档教程链接

当我尝试同步时，它给出了错误。

根据目前https://maven.google.com中的内容，该工件似乎不存在。试试android.arch.navigation:navigation-safe-args-gradle-plugin:1.0.0-alpha01吧。另请参阅此问题。

尝试添加

classpath "android.arch.navigation:navigation-safe-args-gradle-plugin:1.0.0-alpha01"

代替

classpath "androidx.navigation:safe-args-gradle-plugin:1.0.0-alpha01"

如果你不关心参数的类型安全，你可以跳过安全参数部分，你会很好地使用导航组件。
