Grails2.3-新的示例项目不起作用

我创建了一个新的Grails2.3示例项目

刷新依赖项或运行应用程序时出现错误

我的BuildConfig.groovy是：

System.setProperty（“http.proxyHost”、“10.20.30.40”）； System.setProperty（“http.proxyPort”、“80”）

---

将jar添加到应用程序的Lib文件夹中

您可以从下载JAR。

如前所述，您可以使用

添加代理

和

设置代理

为Grails 2.3配置全局代理

grails添加代理客户端--host=proxy服务器--port=4300
--用户名=来宾--密码=来宾

运行该命令时，grails将创建包含代理信息的

${HOME}/.grails/ProxySettings.groovy

。您可以根据自己的心意调整设置

---

需要注意的一点是，您不应该从项目目录运行

grailsaddproxy

，因为它将在尝试设置代理之前尝试解析缺少的依赖项。我只是备份了一个目录来运行它。

直到他们发现maven出了什么问题

在BuildConfig中，将grails.project.dependency.resolver=“maven”更改为grails.project.dependency.resolver=“ivy”

---

别忘了刷新依赖项

我只是通过删除现有的Maven缓存目录（$HOME/.m2）来解决同样的问题。我还没有弄清楚为什么这样做可以解决问题。

你是不是在委托代理人？您是否尝试过通过addproxy命令传递代理配置：这很有效。我在一个单独的cmd终端上运行它们。注意-如果您使用的是GGTS，您必须重新启动它，以便对代理进行更改，以使其正常工作。注意：确保您没有从项目目录中运行此命令。否则grails将首先尝试解决项目的依赖关系，这将失败，因为没有设置代理！
