从java连接到Firebase时发生java.lang.NoSuchMethodError

我正在尝试将我的Java web项目连接到Firebase，以便能够将数据存储在Firestore中。我正在使用Java Admin SDK，遵循官方指南：。遗憾的是，我在初始化FirebaseAp时遇到了异常：

java.lang.NoSuchMethodError: com.google.common.base.Preconditions.checkState(ZLjava/lang/String;Ljava/lang/Object;)V
at com.google.firebase.FirebaseApp.checkNotDeleted(FirebaseApp.java:352)
at com.google.firebase.FirebaseApp.getOptions(FirebaseApp.java:267)
at com.google.firebase.FirebaseApp$TokenRefresher.<init>(FirebaseApp.java:434)
at com.google.firebase.FirebaseApp$TokenRefresher$Factory.create(FirebaseApp.java:535)
at com.google.firebase.FirebaseApp.<init>(FirebaseApp.java:113)
at com.google.firebase.FirebaseApp.initializeApp(FirebaseApp.java:201)
at com.google.firebase.FirebaseApp.initializeApp(FirebaseApp.java:188)

我甚至下载了google firebase sdk的github存储库，并删除了那里的所有guava代码引用，但在尝试读/写Firestore时，我也遇到了类似的错误。似乎其他一些google库也依赖于这个蹩脚的小罐子。

我对不同依赖项中的Guava版本也有同样的问题

我在Gradle这样解决了这个问题：

configurations.all {
    resolutionStrategy {
        force 'com.google.guava:guava:17.0'
    }
}

应该有一个Maven方法，否则从所有依赖项中排除Guava，并在您的版本中显式添加它

它在全球范围内强制执行番石榴版本。幸运的是，17版与我所有的依赖项都兼容。无论是16岁还是18岁以上都不是。。。可悲的是，他们用的是番石榴

希望有帮助，

能否尝试在代码中的某个位置添加以下行，并查看它是否编译<代码>先决条件。检查状态（true，“，new Object（））还有一个可能的修复程序正在开发中，您可以在其中尝试。
