java - 添加 Firestore 时出现重复类

Question

最近将 Firebase-Firestore 添加到我的 Android 项目中，并在构建时开始获取对 protobuf 中的类的重复引用。

// sub-projects/modules.

Answer 1

作为修复，使用 gradle dependency 命令生成 gradle 依赖关系树，该树将向您显示从哪里获取 protobuf-lite-3.0.1.jar 和然后简单地使用 gradle 中的排除模式排除这个 jar，如下所示 -

dependencies {
  compile('com.example.m:m:1.0') {
     exclude group: 'org.unwanted', module: 'x 
  }
}
