How to get groovy grape script startup going faster

I've noticed th开发者_如何学Pythonere is like a 10 second hit using a groovy script with Grape annotations on my OSX box. Is it always this way? Can I make grape favor its cache (the depedencies are definitely already on the system in ~/.groovy/grapes...).

Some libraries (notably httpbuilder) use version ranges in their dependencies. There is a post here which describes how to increase the TTL for this version check in your grapeconfig.xml file.

Do you have a ~/.groovy/grapeConfig.xml file defined? The example given in the doco favours the local cache.
