Java 无法访问 com.google.auth.Credentials

Question

我正在使用 Firebase 为客户端开发一个简单的 JavaFx 应用程序。

此应用程序在没有 JavaFx 的情况下也能完美运行，但是我必须重新创建此项目才能让 JavaFx 使用它（简单地添加依赖项不起作用）。

我知道这个问题可能重复，但我已经尝试了几乎所有之前建议的方法。（链接了我在下面尝试过的那些）

使用 GoogleCredentials 时，应用程序抛出此错误：

java: cannot access com.google.auth.Credentials
  class file for com.google.auth.Credentials not found

这是具有方法的 class：（参见私有构造函数）

public class DataManage {
    private FirebaseOptions options;
    private Firestore firestore;
    private FirebaseAuth mAuth;

    public static DataManage getInstance() {
        return Holder.INSTANCE;
    }

    public void initApp() {
        FirebaseApp.initializeApp(options);
    }

    public UserRecord getUserInfo(String email) {
        try {
            return mAuth.getUserByEmail(email);
        } catch (Exception e) {
            e.printStackTrace();
        }
        return null;
    }

    public void getUserDataFromDate(String email, Date date) {
        try {
            //Todo add stuff later
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    /// I call the GoogleCredentials.fromStream() method here
    private DataManage() {
        try {
            FileInputStream inputStream = new FileInputStream("service-account.json");

            options = FirebaseOptions.builder()
                    .setCredentials(GoogleCredentials.fromStream(inputStream))
                    .setDatabaseUrl("https://attendance-349db.firebaseio.com/")
                    .build();

            FirebaseApp.initializeApp(options);

            firestore = FirestoreClient.getFirestore();
            mAuth = FirebaseAuth.getInstance();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    private static class Holder {
        private static final DataManage INSTANCE = new DataManage();
    }
}

这是我的maven依赖文件：（为了避免混乱，只包含依赖和构建的一部分）

    opens com.indo.attendanceserver to javafx.fxml;
    exports com.indo.attendanceserver;
    exports com.indo.attendanceserver.scenes.intro;
    opens com.indo.attendanceserver.scenes.intro to javafx.fxml;
    exports com.indo.attendanceserver.scenes.user;
    opens com.indo.attendanceserver.scenes.user to javafx.fxml;
}

非常感谢任何帮助。

Answer 1

我已经解决了这个问题。

我所要做的就是添加

requires com.google.auth;

到我的 module-info.java 文件。

最终文件看起来像这样：

module com.indo.attendanceserver {
    requires javafx.controls;
    requires javafx.fxml;
    requires firebase.admin;
    requires google.cloud.firestore;
    requires com.google.auth.oauth2;
    requires com.google.auth;



    opens com.indo.attendanceserver to javafx.fxml;
    exports com.indo.attendanceserver;
    exports com.indo.attendanceserver.scenes.intro;
    opens com.indo.attendanceserver.scenes.intro to javafx.fxml;
    exports com.indo.attendanceserver.scenes.user;
    opens com.indo.attendanceserver.scenes.user to javafx.fxml;
}

我希望这对正在寻找答案的人有所帮助。
