grails upgrading 2.4.0 causes Error Compilation error: startup failed

grails, upgrade

Solution

The holder classes have been removed from Grails 2.4.0. Updating to the latest plugin versions should resolve the compilation errors above.

If you find that the most recent plugin versions don't support Grails 2.4.0, then you'll just have to wait until they release a version that is 2.4.0 compatible before you can upgrade.

From personal experience, I know that the following plugins have 2.4.0 compatible versions:

- resources

- mail

- quartz

But I'm not sure about email-confirmation or joda-time

Problem

I am trying to upgrade from Grails 2.2.3 to Grails 2.4.0. For that I have followed following steps: - using GVM, I have installed grails 2.4.0 - set grails default version to 2.4.0 - then run command to set-grails-version to 2.4.0 in my project directory and then updated java to use oracle jdk 7 I am getting the following error. Any suggestion why? ``` Error Compilation error: startup failed: /home/madan/.grails/2.4.0/projects/mainthub/plugins/mail-1.0/src/groovy/grails/plugin/mail/MailMessageContentRenderer.groovy: 21: unable to resolve class org.codehaus.groovy.grails.plugins.PluginManagerHolder @ line 21, column 1. import org.codehaus.groovy.grails.plugins.PluginManagerHolder ^ /home/madan/.grails/2.4.0/projects/mainthub/plugins/resources-1.2/grails-app/taglib/org/grails/plugin/resource/ResourceTagLib.groovy: 6: unable to resolve class org.codehaus.groovy.grails.commons.ConfigurationHolder @ line 6, column 1. import org.codehaus.groovy.grails.commons.ConfigurationHolder ^ /home/madan/.grails/2.4.0/projects/mainthub/plugins/resources-1.2/src/groovy/org/grails/plugin/resource/ResourceProcessor.groovy: 6: unable to resolve class org.codehaus.groovy.grails.plugins.PluginManagerHolder @ line 6, column 1. import org.codehaus.groovy.grails.plugins.PluginManagerHolder ^ /home/madan/.grails/2.4.0/projects/mainthub/plugins/resources-1.2/src/groovy/org/grails/plugin/resource/util/HalfBakedLegacyLinkGenerator.groovy: 3: unable to resolve class org.codehaus.groovy.grails.commons.ConfigurationHolder @ line 3, column 1. import org.codehaus.groovy.grails.commons.ConfigurationHolder ^ /home/madan/.grails/2.4.0/projects/mainthub/plugins/joda-time-1.4/grails-app/taglib/grails/plugin/jodatime/taglib/PeriodTagLib.groovy: 18: unable to resolve class org.codehaus.groovy.grails.commons.ConfigurationHolder @ line 18, column 1. import org.codehaus.groovy.grails.commons.ConfigurationHolder ^ /home/madan/.grails/2.4.0/projects/mainthub/plugins/email-confirmation-2.0.8/grails-app/services/com/grailsrocks/emailconfirmation/EmailConfirmationService.groovy: 24: unable to resolve class org.codehaus.groovy.grails.commons.ConfigurationHolder @ line 24, column 1. import org.codehaus.groovy.grails.commons.ConfigurationHolder ^ /home/madan/.grails/2.4.0/projects/mainthub/plugins/email-confirmation-2.0.8/grails-app/services/com/grailsrocks/emailconfirmation/EmailConfirmationService.groovy: 25: unable to resolve class org.codehaus.groovy.grails.commons.ApplicationHolder @ line 25, column 1. import org.codehaus.groovy.grails.commons.ApplicationHolder ^ /home/madan/.grails/2.4.0/projects/mainthub/plugins/quartz-1.0-RC2/grails-app/conf/QuartzBootStrap.groovy: 18: unable to resolve class org.codehaus.groovy.grails.commons.ConfigurationHolder @ line 18, column 1. import org.codehaus.groovy.grails.commons.ConfigurationHolder ^ /home/madan/.grails/2.4.0/projects/mainthub/plugins/quartz-1.0-RC2/grails-app/conf/QuartzBootStrap.groovy: 31: unable to resolve class org.codehaus.groovy.grails.commons.ConfigurationHolder @ line 31, column 12. if(ConfigurationHolder.config?.quartz?.autoStartup) quartzScheduler.start() ^ /home/madan/.grails/2.4.0/projects/mainthub/plugins/joda-time-1.4/src/groovy/grails/plugin/jodatime/binding/DateTimeEditor.groovy: 20: unable to resolve class org.codehaus.groovy.grails.commons.ConfigurationHolder @ line 20, column 1. import org.codehaus.groovy.grails.commons.ConfigurationHolder ^ /home/madan/.grails/2.4.0/projects/mainthub/plugins/joda-time-1.4/src/groovy/grails/plugin/jodatime/binding/DateTimeEditor.groovy: 30: unable to resolve class org.codehaus.groovy.grails.commons.ConfigurationHolder @ line 30, column 38. @Lazy private ConfigObject config = ConfigurationHolder.config?.jodatime?.format ^ 11 errors ```
