java.lang.NoSuchMethodError : com. google.common.base.Preconditions.checkArgument

Question

我正在尝试运行 grpc-Java我本地的例子。对应的 proto 文件是 here .当我尝试在本地运行时，它会从 here 引发以下异常:

Exception in thread "main" java.lang.NoSuchMethodError: com.google.common.base.Preconditions.checkArgument(ZLjava/lang/String;Ljava/lang/Object;Ljava/lang/Object;)V

这是我提到的 pom.xml here :
