实施'com.android.support:appcompat-v7:28.0.0'无法同步

Question

build.gradle：

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.android.support:support-v4:28.0.0'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
    implementation 'com.google.android.material:material:1.0.0-rc01'
    implementation 'com.google.firebase:firebase-core:17.0.0'
    implementation 'com.google.firebase:firebase-messaging:19.0.1'


    implementation 'com.android.support:support-annotations:28.0.0'
}

    apply plugin: 'com.google.gms.google-services'

模块应用程序由于添加了此标签"firebase message"而无法同步，并且可以从上面的代码行中看到此行下的错误。
