导入语句中的错误无法解析符号FirebaseAuth

Question

在Firebase的import语句中突出显示为红色

执行clean and rebuild project后，该错误尚未解决。在build.gradle中添加了依赖项，但仍然没有任何反应 请帮忙。

apply plugin: 'com.android.application'
android {
    compileSdkVersion 27
    defaultConfig {
        applicationId "com.example.admin.myapp"
        minSdkVersion 16
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}
