Cloud Foundry 无法部署 grails 应用程序 [UnknownHostException]

Question

我最近尝试在 Cloud Foundry 上部署 Grails 项目，执行“grails cf-push”时出现以下错误

Environment set to production.....
Error Error executing script_ CfPush: org.springframework.web.client.ResourceAccessException: I/O error on POST request for "http://api.cloudfoundry.com/users/username@gmail.com/tokens":api.cloudfoundry.com; nested exception is java.net.UnknownHostException: api.cloudfoundry.com (Use --stacktrace to see the full trace)

对于“grails cf-push --stacktrace”：

Error Error executing script_ CfPush: org.springframework.web.client.ResourceAccessException: I/O error: api.cloudfoundry.com; nested exception is java.net.UnknownHostException: api.cloudfoundry.com (NOTE: Stack trace has been filtered. Use --verbose to see entire trace.)

几个月前一切正常，但我不得不停止该项目的工作一段时间。当我重新开始使用它时，我意识到不再可以像往常那样部署它。

我认为我需要升级我的 cloud-foundry 插件，所以在一天的工作中我升级了整个 groovy/grails 环境：

groovy 2.0.5 到 2.1.9 grails 2.1.2 到 2.3.1

使用以下说明连同项目本身： http://grails.org/doc/2.3.0.M1/guide/upgradingFromPreviousVersionsOfGrails.html

依赖关系自行解决相当顺利（以及最新的 cloud-foundry 1.2.3 插件）。但是部署仍然失败并出现同样的错误。

“vmc info”告诉我“api.cloudfoundry.com”不存在。 我出主意了。地址改了吗？是否有任何按惯例解决问题的方法，或者这里发生了什么其他事情？

“api.cloudfoundry.com”是托管的 Cloud Foundry v1 的 URL，它不再存在。 “cloudfoundry.com”已被http://run.pivotal.io取代，即Cloud Foundry v2。

Cloud Foundry Grails 插件尚未更新以支持 CF v2。您应该使用“cf”CLI 来与 CF 交互，而不是使用 Grails 插件脚本。请参阅http://docs.cloudfoundry.com/docs/using/managing-apps/cf/index.html 和http://docs.cloudfoundry.com/docs/using/deploying-apps/jvm/index.html。
