我正在尝试运行 groovy koans http://groovykoans.org/，当我使用 gradlew 脚本时，它会尝试从 Internet 下载 gradle（来自http://services.gradle.org/distributions/gradle-1.8-bin .zip )

但它因连接超时异常而崩溃。我可以从 Firefox 下载文件。我按照说明在命令行中包含了 http 代理 args，我可以从我的机器上 ping services.gradle.org。

我在窗户上。

C:\Users\me\My Documents\documents\work\build_system\groovykoans-master>gradlew removeSolutions -Dhttp.proxyHost=proxy.blah.com -Dhttp.proxyPort=8000

如果我无法解决连接问题，是否有办法手动安装已通过浏览器成功下载的 gradle 并绕过 gradlewrapper 的下载步骤？

好吧，我设法弄清楚了 gradle zip 的放置位置（C:\Users\me\.gradle\wrapper\dists\gradle-1.8-bin\vruqmccc8532n7gr46qavsii8 所以我将单独下载的 zip 放在那里，它让我通过了问题。

但是从那时起，我也意识到我在命令之后而不是在命令之前指定了 -Dhttp 属性，所以我怀疑如果我这样做了它会起作用。（虽然没有用干净的安装区域重试）即我应该有

gradlew -Dhttp.proxyHost=proxy.blah.com -Dhttp.proxyPort=8000 removeSolutions

代替：

gradlew removeSolutions -Dhttp.proxyHost=proxy.blah.com -Dhttp.proxyPort=8000

呃！
