问题
recently tried to deploy a grails-app to cloud foundry, the app is running perfectly @ localhost but after cf-push with cloud-foundry plugin, the console is stuck at Starting application and when trying to acces url: myapp.cloudfoundry.com, i have:
Error 500 - Internal Server Error.
groovy.lang.Closure.rehydrate(Ljava/lang/Object;Ljava/lang/Object;Ljava/lang/Object;)Lgroovy/lang/Closure;
What does mean this error ?
edit: here are the logs:

回答1:
On your question above "What does this error mean?", it looks like stdout messages are being reported to the error logs which isn't giving us much information. Here are some ideas, 1) deploy a sample app to insure things are working, 2) simplify your app to the point where it deploys successfully, 3) incrementally enable additional functionality until it breaks, 4) try to use available tools like debug in STS to investigate further, cloudfoundry docs

This may be the same problem as stated in this question: https://stackoverflow.com/a/12469996/187812
The answer in that thread was that "Closure.rehydrate was introduced in Groovy 1.8.5", and the questioner had an older version of Groovy associated with their project.
