Question

我尝试将databinding用于我的应用，但是gradle构建失败。我无法解决这个问题。需要你的帮助。

我遇到错误

    Unable to resolve dependency for ':app@debug/compileClasspath': Could not resolve com.android.databinding:library:3.1.0.

    Unable to resolve dependency for ':app@debug/compileClasspath': Could not resolve com.android.databinding:adapters:3.1.0.

    Unable to resolve dependency for ':app@debugAndroidTest/compileClasspath': Could not resolve com.android.databinding:library:3.1.0.

app level gradle file

apply plugin: 'com.android.application'
android {
    compileSdkVersion 26
    defaultConfig {
        applicationId "com.example.dell.pitchpls"
        minSdkVersion 21
        targetSdkVersion 26
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    buildToolsVersion '27.0.3'
    dataBinding{
        enabled = true
    }
}
dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')

    implementation 'com.android.support:design:26.1.0'

    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}
apply plugin: 'com.google.gms.google-services'

项目级别gradle文件

buildscript {
repositories {
    google()
    jcenter()
}
dependencies {
    classpath 'com.android.tools.build:gradle:3.1.0'
    classpath 'com.google.gms:google-services:4.0.1'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}
allprojects {
    repositories {
        google()
        jcenter()
    }
}
task clean(type: Delete) {
    delete rootProject.buildDir
}

在启用数据绑定到项目时，Grable构建失败
