我在IntelliJ中运行Java Firebase服务器应用程序时工作正常，但.class文件未运行

Question

我编写了一个小服务器应用程序以在Firebase Firestore上运行一些命令。当我在IntelliJ中运行该项目时，它就像一个魅力。因此，我现在想将.class文件发送到我的服务器上，以便在该服务器上运行它，但是由于某种原因，我既不能在我正在编程的计算机上也不能在服务器上运行它。

控制台中的

“ java MyFirebaseServer”给我以下错误：

错误：无法初始化主类MyFirebaseServer 造成原因：java.lang.NoClassDefFoundError：com / google / auth / oauth2 / GoogleCredentials

我在这个项目中使用过maven，但我对此并不熟悉，也许我只是不明白这一点。

这是ServerClass的代码，我将其精简到最小，恰好可以重现错误：

import com.google.auth.oauth2.ServiceAccountCredentials;
import com.google.firebase.FirebaseOptions;

import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;


public class MyFirebaseServer {

    public static void main(String[] args) {
        System.out.println("HelloWorld");

        FileInputStream serviceAccount =
                null;
        try {
            serviceAccount = new FileInputStream("/Users/myserviceaccountfile.json");
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        }




        FirebaseOptions options;
        options = null;
        try {
            options = new FirebaseOptions.Builder()
                    .setCredentials(ServiceAccountCredentials.fromStream(serviceAccount))
                    .setDatabaseUrl("here goes my db url")
                    .build();
        } catch (IOException e) {
            e.printStackTrace();
        }

    }

}

现在是pom了，可能是一团糟，因为我对maven并不了解：

有人有类似的问题吗？或者我知道哪里出问题了吗？

预先感谢
