无法翻墙情况下，无法使用Freeline。报错Could not resolve all files for configuration ':classpath'.

[feixiang19913]

gradle配置是4.1，AS版本是3.0.1
代码中改动如下：
主项目的build.gradle中dependence添加classpath 'com.antfortune.freeline:gradle:0.8.8'
app的build.gradle中添加apply plugin: 'com.antfortune.freeline'
以及testCompile 'junit:junit:4.12'
debugCompile 'com.antfortune.freeline:runtime:0.8.8'
releaseCompile 'com.antfortune.freeline:runtime-no-op:0.8.8'
testCompile 'com.antfortune.freeline:runtime-no-op:0.8.8'
initFreeline后项目中出现了Freeline和Freeline-core文件夹
工具栏出现Freeline图标按键

但是运行Freeline后出现以下报错：
python freeline.py

但是在Android Studio文件夹中我找到了gradle-3.0.1.pom文件。
求问，有没有人遇到相似问题，怎么解决的？

你这是缺少Google仓库，gradle plugin3.0+已经不再从jcenter下载了，所以需要设置google仓库
