Android：未找到Firebase导入

我正在学习使用Firebase，但是导入方面有一些问题。我的项目如下所示：

我找不到适合依赖的进口产品。

    error: cannot find symbol
                    .addOnFailureListener(new OnFailureListener() {
                                              ^
      symbol:   class OnFailureListener
error: cannot find symbol
                .addOnSuccessListener(new OnSuccessListener<Void>() {
                                          ^
  symbol:   class OnSuccessListener

但是如果我添加这一行：

import com.google.android.gms.tasks.*;

它编译成功。但是线条仍然是红色的。而且gms.tasks中没有类如何解决它？

  compileSdkVersion 27
    buildToolsVersion '27.0.3'

    defaultConfig {
        applicationId "com.google.firebase.udacity.friendlychat"
        minSdkVersion 16
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"
    }

    implementation fileTree(dir: 'libs', include: ['*.jar'])
