我已经在我的grails项目上安装了 cloud foundry插件，并且我已经成功将我的项目推送到云端但是当我尝试使用时更新我的应用程序时，
grails prod cf-update
命令。当我这样做时，我收到以下错误：
ERROR - Application 'scheduleNew' failed to start, logs information below.

当我再次运行相同的命令（grails prod cf-update）时，错误消息发生了变化：
ERROR - Application 'scheduleNew' failed to start, logs information below.

我真的不明白这里发生了什么。
这些错误消息说什么？哪里出错了？

还有其他日志文件。如果使用http://grails-plugins.github.com/grails-cloud-foundry/docs/manual/ref/Scripts/cf-list-files.html命令，则可以获得目录列表。运行grails cf-list-files /以获取顶级目录的列表（它将包含logs和tomcat目录）。 logs目录可能只包含您已经看到的stderr和stdout文件，但tomcat目录下还有另一个日志目录：grails cf-list-files /tomcat/logs。这应该有其他更丰富的日志文件。同时检查stacktrace.log目录中是否有tomcat。
找到要查看的文件后，使用http://grails-plugins.github.com/grails-cloud-foundry/docs/manual/ref/Scripts/cf-get-file.html命令查看它们，例如
grails cf-get-file /tomcat/stacktrace.log
grails cf-get-file /tomcat/logs/catalina.2012-01-24.log
