续上篇配置Gradle 国内镜像源: 全局配置&单独配置添加完镜像之后，仍旧无法正常下载包.. 报 Could not resolve ... 或者是 Could not GET ... 诸如此类。报错信息的最后一条还有 Connect to 127.0.0.1:1080 [/127.0.0.1] failed: Connection refused: connect。 我想了想也许是Gradle 开了代理, 百度了一下，找到此解决方案：Android Studio Could not GET gradle-3.2.0.pom (安卓包配置相关问题) 。按照文章指示将gradle.properties配置文件中的代理配置关掉了(在代理配置信息行前加#)。
# systemProp.https.proxyPort=1080
# systemProp.http.proxyHost=127.0.0.1
# systemProp.https.proxyHost=127.0.0.1
# systemProp.http.proxyPort=1080
关掉后似乎是解决包下载的问题了，然而又报了内存溢出的问题..
