问题 There is a directory that is being served over the net which I'm interested in monitoring. Its contents are various versions of software that I'm using and I'd like to write a script that I could run which checks what's there, and downloads anything that is newer that what I've already got.

问题 Why cant I set a version info in a Dunit Test projet? The checkbox is disabled for this projetct, but not for other projects.

问题 Short question: I want to run a certain code in my app only if my Core Data model has changed (new entities, new properties, etc). How can I determine if the model has changed or not?

问题 What are the risks associated with updating from ExtJS 3.x to Ext JS 4 Beta? Would you expect that user extensions which work with Ext JS 3.x will work with Ext JS 4 Beta?

问题 Is it possible to obtain version of a specific Grails plugin at runtime, let say in Bootstrap class? Or more generically, how to query loaded plugins from the parent Grails applications and obtain their names and version numbers? 回答1: The simplest way is to interact with the pluginManager bean. class BootStrap { def pluginManager def init = { servletContext -> // retrieve them all... pluginManager.allPlugins.each { plugin -> println "Plugin: ${plugin.name}, Version: ${plugin.version}" } //
