AS 警告 You have JVM property https.proxyHost set proxy balbala

然后更新lib 报
Connect to 127.0.0.1:1086 [/127.0.0.1] failed: Connection refused: connect

原因是之前设置了proxy
然后本地
user目录下的 .gradle就记录了这个值

systemProp.https.proxyPort=1086
systemProp.http.proxyHost=127.0.0.1
systemProp.https.proxyHost=127.0.0.1
systemProp.http.proxyPort=1086

删除之后就行了
