我在Android Studio中。 我需要在项目中添加必要的依赖项。 我正在使用经过身份验证的代理。
我在项目中的gradle.properties配置如下：
systemProp.http.proxyHost=my.proxy.host
systemProp.http.proxyPort=3128
systemProp.http.proxyUser=myUser
systemProp.http.proxyPassword=myPassword
systemProp.http.nonProxyHosts=localhost
systemProp.http.auth.ntlm.domain=cha.jovenclub.cu
systemProp.https.proxyHost=my.proxy.host
systemProp.https.proxyPort=3128
systemProp.https.proxyUser=myUser
systemProp.https.proxyPassword=myPassword
systemProp.https.nonProxyHosts=localhost
systemProp.https.auth.ntlm.domain=cha.jovenclub.cu
但是当我开始同步时，下载依赖项时会返回403 Forbidden错误，具体是这样：

我不会粘贴整个错误，因为这是最重要的部分
现在，如果我获取依赖项URL（.pom或.jar文件）并将其粘贴到浏览器（firefox，chrome）中，则它将正确返回文件。 当然，浏览器也位于同一经过身份验证的代理下。
因此，浏览器没有问题，但Android Studio检索相同文件失败。
我的sysAdmin愿意为我提供帮助，但是他需要了解确切地执行操作，问题从何而来。 出于安全原因，放弃代理不是一种选择。
我非常感谢您的帮助，因为如果项目不同步，我将无法工作。
预先感谢
