我正在尝试解决 gradle 项目的依赖关系，当我打开项目并尝试同步 gradle 时，出现以下错误：
错误：连接超时：连接。如果您使用 HTTP 代理，请在 IDE 或 Gradle 中配置代理设置。
然后我意识到我需要在gradle中配置公司网络的代理，我在gradle.properties文件中设置了代理：
systemProp.http.proxyHost=someIP
systemProp.http.proxyPort=somePort
systemProp.http.proxyUser=user
systemProp.http.proxyPassword=pswd
systemProp.http.nonProxyHosts=*.nonproxyrepos.com|localhost
systemProp.https.proxyHost=someIP
systemProp.https.proxyPort=somePort
systemProp.https.proxyUser=user
systemProp.https.proxyPassword=pswd
systemProp.https.nonProxyHosts=*.nonproxyrepos.com|localhost
然后我尝试同步 gradle 项目，但我得到了同样的错误：
错误：连接超时：连接。如果您使用 HTTP 代理，请在 IDE 或 Gradle 中配置代理设置。
该gradle.properties文件位于以下路径中：
project/gradle.properties
我gradlew.bat从命令行执行，我得到了下一个异常：
