我正在使用 firebase Admin SDK 并且我在运行时收到此错误：

Error:(22, 36) java: cannot access com.google.auth.Credentials
class file for com.google.auth.Credentials not found

这是抛出错误的构造函数

import com.google.auth.oauth2.GoogleCredentials;
import com.google.firebase.FirebaseApp;
import com.google.firebase.FirebaseOptions;
import com.google.firebase.database.*;

import java.io.IOException;
import java.io.InputStream;
import java.util.ArrayList;

class Database{

private FirebaseDatabase firebaseDatabase;

Database(){

    InputStream serviceAccount = Database.class.getResourceAsStream("reading-incentive-firebase-adminsdk-n556s-1b742e4b58.json");

    FirebaseOptions options;
    try {
        options = new FirebaseOptions.Builder()
                .setCredentials( GoogleCredentials.fromStream(serviceAccount))
                .setDatabaseUrl("https://reading-incentive.firebaseio.com")
                .build();
        FirebaseApp.initializeApp(options);
    } catch (IOException e) {
        e.printStackTrace();
        System.out.println("Error loading database");
    }

    firebaseDatabase = FirebaseDatabase.getInstance();

}

}

这是第 22 行

.setCredentials(GoogleCredentials.fromStream(serviceAccount))

我在 IntelliJ 中使用 java sdk 1.8 …

我一直主要在 API 26 和 27 上测试我的应用程序，这是我现在正在学习的一个大错误。该应用程序在 API 24、25、26 和 27 中启动时没有崩溃。Google 的发布前报告随后引起了我对 API 23 及以下版本的崩溃的注意。日志有关于菜单的列表，所以我调试它并发现它在我调用时崩溃

MenuInflater inflater = getMenuInflater();

inflater.inflate(R.menu.actionbar_menu, menu);

这是之后返回的错误：
