Question

当前，我正在尝试将项目升级到android x，但在此之前，我完成了gradle包装器4.10.1和tools.build:gradle:3.2.0，但是我遇到以下错误，并且我所有的代码都仅使用Java。

任何人都知道如何解决此类问题。

在Android Plugin 3.2.0及更高版本中，默认情况下启用数据绑定V2。我想数据绑定V2编译器会将以大写字母开头的任何组件都视为一个类，而不是一个包

更改小写字母后，其效果类似于“ adddetail”而不是“ AddDetail”。导入com.ProjectMs.viewmodel.adddetail;

谢谢。参考网址 Gradle Plugin 3.2.0 with databinding, can not resolve package name
