我正在尝试在运行 Windows 10 的工作计算机上设置 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，指向解压缩的 Grails 目录，并将其 bin 子目录的路径添加到系统路径中，同时grails -v工作并输出 Grails 的版本, Gradle 和 Java 正确，基本上没有其他命令。

当我尝试使用 创建一些示例应用程序时grails create-app someApp，我得到| Error Error initializing classpath: services.gradle.org如下跟踪：

同样，当我尝试下载一个项目（例如从 start.grails.org 生成的项目）并在本地运行它时grailsw run-app，我得到：

即使是简单的帮助命令也不起作用导致grails -help输出| Error Error occurred running Grails CLI: repo.grails.org

这可能是什么原因？公司防火墙是否阻止了某些东西？我怎样才能使这项工作？

您提到了公司代理；您可以在 gradle.properties 中设置您的代理，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>
