我開始了一個新項目并放置了火基云：apply plugin: 'com.android.application'apply plugin: 'android-apt'android {    compileSdkVersion 28    buildToolsVersion "28.0.3"    defaultConfig {        applicationId "android.example.com.squawker"        minSdkVersion 16        targetSdkVersion 28        versionCode 1        versionName "1.0"        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"    }    buildTypes {        release {            minifyEnabled false            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'        }    }}dependencies {    implementation fileTree(dir: 'libs', include: ['*.jar'])    androidTestImplementation('com.android.support.test.espresso:espresso-core:2.2.2', {        exclude group: 'com.android.support', module: 'support-annotations'    })    //noinspection GradleCompatible    implementation 'com.android.support:appcompat-v7:28.0.0'    testImplementation 'junit:junit:4.12'// RecyclerViewimplementation 'com.android.support:recyclerview-v7:28.0.0'// Schematic dependencies for ContentProviderapt 'net.simonvt.schematic:schematic-compiler:0.6.3'implementation 'net.simonvt.schematic:schematic:0.6.3'// Preferences Dependenciesimplementation 'com.android.support:preference-v7:28.0.0'// Firebase dependency    implementation 'com.google.firebase:firebase-messaging:17.3.4'}// Apply the Google Services plugin.

You download it from the Firebase consoleapply plugin: 'com.google.gms.google-services'這個錯誤出現了：警告：API 'variant.getJavaCompile()' 已過時，已替換為 'variant.getJavaCompileProvider()'。它將在 2019 年底被刪除。有關更多信息，請參閱https://d.android.com/r/tools/task-configuration-avoidance。要確定調用 variant.getJavaCompile() 的內容，請在命令行上使用 -Pandroid.debug.obsoleteApi=true 以顯示堆棧跟蹤。受影響的模塊：app
