• Upgrade Steps
  
  • Backup all application files
  • Add following statements into the grails-app/conf/Config.groovy file
    

       //upgrade
    grails.views.enable.jsessionid=false
    //grails.project.plugins.dir="./plugins"
    

  • Create a file grails-app/conf/BuildConfig.groovy file if this file doesn't exist and add following statements into this file.
    

     //upgrade
    //grails.views.enable.jsessionid=false
    grails.project.plugins.dir="./plugins"
    

  • if you use some plugins, you need to re-install plugins.
    Remove all plugins files and cleanup files stored under plugins directory
    

       mv plugins/* /tmp/

  • Run the upgrade command as follows
    (After running this commands, grails will create a new plugin named hibernate-1.1 under the plugins directory automatically. we don't need to re-install this hibernate-1.1 plugin.)
    

    grails upgrade

  • re-install plugins by using "grails install-plugins" command
    

    (for example)
    grails install-plugin /tmp/grails-quartz-0.3.1.zip

    • Error Stack
      

      2009-04-14 16:12:39,907 [main] ERROR context.ContextLoader  - Context initialization failed
      org.springframework.beans.factory.access.BootstrapException: Error executing bootstraps; nested exception is org.codehaus.groovy.runtime.InvokerInvocationException: groovy.lang.MissingPropertyException: No such property: startDelay for class: QuartzGrailsPlugin

       at org.springframework.web.context.ContextLoaderListener.contextInitialized(ContextLoaderListener.java:45)
      

    • Cause
      This error raises from following statements of the configureJobBeans closure in the QuartzGrailsPlugin.groovy file because of the "this" clause.
      

            // registering triggers
        jobClass.triggers.each {name, trigger ->
            "${name}Trigger"(trigger.clazz) {
                jobDetail = ref("${fullName}JobDetail")
                trigger.properties.findAll {it.key != 'clazz'}.each {
                    this["${it.key}"] = it.value  /* here */
                }
             }
        }
      

    • Resolution
      I changed this clause from "this" to "delegate", quartz plugin works fine.
