我在Android Studio Mac中添加了代理配置，并且检查连接运行良好。 但是当我尝试同步gradle文件或构建proj时，它会抛出错误
Connect timed out
，然后在首选项->系统设置-> HTTP代理上 检查连接是否正常。 但它显示警告-
you have JVM property "HTTPsproxy" set to "*******" This may lead to incorrect behaviour.Proxy should be set in settings |HTTP proxy. The JVM property is old and its usage is not recommended by Oracle.```
