Can'；尽管路径正确，但不要使用Grails

我试图在运行Windows10的计算机上设置Grails，但我无法这样做。我已经从网站（3.3.8）下载了最新版本，在我的帐户中添加了一个GRAILS_HOME变量，指向解压后的GRAILS目录，并将其bin子目录的路径添加到系统路径中，虽然

GRAILS-v

可以正常工作并输出GRAILS、Gradle和Java的版本，但基本上没有其他命令这样做

当我尝试使用

grails create app someApp

创建一些示例应用程序时，我在初始化classpath:services.gradle.org时遇到了

即使是一个简单的help命令也不起作用，因为运行grails CLI:repo.grails.org时发生了错误

原因可能是什么？公司防火墙阻止了什么吗？我怎样才能做到这一点呢？
你提到的是公司代理；您可以在gradle.properties中设置代理，如下所示：

systemProp.https.proxyHost=<your proxy>
systemProp.https.proxyPort=<your port>
systemProp.http.proxyHost=<probably same>
systemProp.http.proxyPort=<probably same>
systemProp.http.nonProxyHosts:<optional.  comma-separated.  probably at least want localhost in there: *.domain.com,localhost>

systemProp.https.proxyHost=
systemProp.https.proxyPort=
systemProp.http.proxyHost=
systemProp.http.proxyPort=
systemProp.http.nonProxyHosts：
哦，你真的提到了公司防火墙。我猜还有一个代理。是的，但问题是，为了编辑gradle.properties，我首先需要创建应用程序，因为有错误，我不能这样做。唯一的选择是每次使用在线工具生成应用程序，然后编辑属性。另外，我不知道我公司的代理，从我询问的情况来看，没有人知道。没有解决办法吗（好的，我设法得到了代理信息，现在它像一个符咒一样工作-非常感谢！）
