Java 编译firebase管理员代码时出错

编译Firebase管理员代码时出错

错误：

根据来自的信息，我尝试一个接一个地添加所有依赖项

添加

testCompile group: 'org.apache.logging.log4j', name: 'log4j-slf4j-impl', version: '2.13.3'

或

或

或

或

不会删除错误。 我能知道我出了什么问题吗

我的Gradle文件：

plugins {
    id 'java'
}

group 'org.example'
version '1.0-SNAPSHOT'

sourceCompatibility = 1.8

repositories {
    mavenCentral()
}

dependencies {
    testCompile group: 'junit', name: 'junit', version: '4.12'
    implementation 'com.google.firebase:firebase-admin:6.13.0'
//None of these seem to remove the error
//    testCompile group: 'org.apache.logging.log4j', name: 'log4j-slf4j-impl', version: '2.13.3'
//    testCompile group: 'org.slf4j', name: 'slf4j-nop', version: '1.8.0-beta4'
//    testCompile group: 'org.slf4j', name: 'slf4j-simple', version: '1.8.0-beta4'
//    testCompile group: 'org.slf4j', name: 'slf4j-jdk14', version: '1.8.0-beta4'
//    testCompile group: 'ch.qos.logback', name: 'logback-classic', version: '1.2.3'

我的主课

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;

public class MainClass {
    public static void main(String[] args) throws IOException {
        FirebaseOptions options = new FirebaseOptions.Builder()
                .setCredentials(GoogleCredentials.getApplicationDefault())
                .setDatabaseUrl("https://{my database name}.firebaseio.com/")
                .build();

        FirebaseApp.initializeApp(options);
        DatabaseReference ref = FirebaseDatabase.getInstance()
                .getReference("restricted_access/secret_document");
        ref.setValue("hiIII", new DatabaseReference.CompletionListener() {
            @Override
            public void onComplete(DatabaseError error, DatabaseReference ref) {
                System.out.println("Completed");
            }
        });
    }
}

我能知道我出了什么问题吗？如何更正它？

当org.slf4j.impl.StaticLoggerBinder类无法加载到内存中时，会报告此警告消息。当在类路径上找不到合适的SLF4J绑定时，就会发生这种情况。将slf4j-nop.jar、slf4j-simple.jar、slf4j-log4j12.jar、slf4j-jdk14.jar或logback-classic.jar中的一个（且仅一个）放在类路径上应该可以解决问题

如果此问题无法解决，请尝试清除缓存并重新启动。

我也尝试过这样做，但不起作用。因为我使用的是Gradle，添加到类路径基本上就是添加它的实现，对吗？是的，这就是我告诉你的原因！另外，我可以知道如何清除intellij IDE中的捕获吗？从主菜单中，选择文件|使缓存无效/重新启动。在“使缓存无效”对话框中，选择一个操作。您可以使缓存无效并重新启动IDE，在不重新启动IDE的情况下使缓存无效，或者只重新启动IDE。
