排除等级无效。 目前，我在Android应用程序中使用Firebase Firestore，Firestore在内部使用“ protobuf-lite”，而该库与另一个使用“ protobuf-java”的库发生冲突，这会导致重复的gradle错误并构建失败。

我在Firestore实现中添加了一条规则，以排除与其他库冲突的这些模块
implementation('com.google.firebase:firebase-firestore:20.1.0', {
exclude group: 'com.google.firebase', module:'protolite-well-known-types'
exclude group: 'com.google.firebase', module:'protobuf-lite'
exclude group: 'com.google.protobuf', module:'protobuf-lite'
})
现在，项目成功构建并且应用程序运行，但是当我执行任何Firestore操作时，应用程序崩溃，这意味着它们不仅从应用程序模块中排除在Firestore库本身之外。

问题是： 不排除意味着不要将这些模块从Firestore库导入到应用程序模块，而不要将其从Firestore中删除吗？ 如果没有，那么如何使它们仅可用于内部Firestore并隐藏在应用程序模块中，以避免任何冲突和重复的类错误。
========更新========== 我解决了这个问题 由于我们无法更改依赖于protolite版本的Firestore内部代码，因此唯一的方法是更改依赖proto-java的其他模块以使用protolite修复此重复错误，并执行此操作 我必须使用protobuf lite编译器从proto文件生成Java类，该java类将生成依赖于protolite库而不是proto-jave的类，现在我可以将Proto-lite库用于Firestore和其他Module以及重复类错误消失了。
