ERROR: Failed to resolve: com.android.databinding:baseLibrary:3.5.2

错误如下：

ERROR: Failed to resolve: com.android.databinding:baseLibrary:3.5.2

解决方法：

//缺少google仓库，增加google仓库
allprojects {
    repositories {
        google()
        jcenter()
        maven { url 'https://maven.fabric.io/public' }
    }
}

完整build.gradle: 

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
        google()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.5.2'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
        google()
        maven { url 'https://maven.fabric.io/public' }
    }
}

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