make project时遇到这样一个问题，查看日志似乎是某个东西无法下载，多方查找后发现是gardle引入ButterKnife时版本有问题，将ButterKnife版本从8.8.1改成8.4.0就好了。估计是由于我国特色导致某个下载地址不能访问。

解决办法

在build.gradle（app）中将ButterKnife的版本降低

    //noinspection GradleDependency
    implementation 'com.jakewharton:butterknife:8.4.0'
    //noinspection GradleDependency
    annotationProcessor 'com.jakewharton:butterknife-compiler:8.4.0'

更新(2018/9/28)：今天在引入okhttp时发现了同样的问题，找到了新的解决办法：
在build.gradle (project) 中buildscript和allprojects的repositories下加上阿里的仓库maven { url 'http://maven.aliyun.com/nexus/content/groups/public/' }，如下

buildscript {
    repositories {
        maven { url 'http://maven.aliyun.com/nexus/content/groups/public/' }
        google()
        jcenter()
    }
    ...
 }
 ...
allprojects {
    repositories {
        maven { url 'http://maven.aliyun.com/nexus/content/groups/public/' }
        mavenCentral()
        google()
        jcenter()
    }
}

这样就可以使用最新的版本了，而且build速度也提升不少。
