專案啟動突然遇到：

Could not find runtime.aar (android.arch.lifecycle:runtime:1.0.3).
Searched in the following locations:
    https://jcenter.bintray.com/android/arch/lifecycle/runtime/1.0.3/runtime-1.0.3.aar
 搞了半天 找到解決辦法 ：

在Build.gradle 中 ：

buildscript {
    repositories {
        jcenter()  
        mavenCentral()
        maven { url 'https://maven.fabric.io/public' }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.3.3'
        classpath 'org.greenrobot:greendao-gradle-plugin:3.2.0'
        classpath 'com.google.gms:google-services:3.1.0'
        classpath 'io.fabric.tools:gradle:1.+'

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

allprojects {
    repositories {
        maven { url 'https://maven.google.com' }
        maven { url 'https://tokbox.bintray.com/maven' }
        maven { url "https://jitpack.io" }
        jcenter() //在上面
        mavenCentral() //在下面
    }
}
