Question

我的gradle像下面这样：

buildscript {
    repositories {
        maven { url 'https://plugins.gradle.org/m2/'}
    }
    dependencies {
        classpath 'gradle.plugin.com.onesignal:onesignal-gradle-plugin:[0.11.0, 0.99.99]'
    }
}
apply plugin: 'com.onesignal.androidsdk.onesignal-gradle-plugin'

repositories {
    maven { url 'https://maven.google.com' }
}

apply plugin: 'com.android.application'
//apply plugin: 'io.fabric'
apply plugin: 'com.google.firebase.firebase-crash'

repositories {
    jcenter()
}

android {
    compileSdkVersion 27
    buildToolsVersion '27.0.3'

    defaultConfig {
        applicationId "ww.ww.ww"
        manifestPlaceholders = [onesignal_app_id               : "www-0a8b-4ebd-86be-www",
                                // Project number pulled from dashboard, local value is ignored.

    }
    buildTypes {
        release {
            lintOptions {
                disable 'MissingTranslation'
                checkReleaseBuilds false
                // Or, if you prefer, you can continue to check for errors in release builds,
                // but continue the build even when errors are found:
                abortOnError false
            }

        }
        debug {
            applicationIdSuffix '.debug'
        }
    }

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    androidTestImplementation('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'

    implementation 'org.minidns:minidns-client:0.3.0'
}

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

然后：

buildscript {
    repositories {
        jcenter()
        google()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.4'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
        classpath 'com.google.gms:google-services:4.0.2'
        classpath 'com.google.firebase:firebase-plugins:1.1.5'
    }
}

allprojects {
    repositories {
        jcenter()
        mavenCentral()
        maven {
            url 'https://maven.google.com'
        }
        google()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

但是让我听到以下错误：

Failed to resolve: support-fragment
Failed to resolve: firebase-messaging
