grails升级2.4.0导致错误编译错误:启动失败

Question

我正在尝试从Grails 2.2.3升级到Grails 2.4.0.为此我遵循了以下步骤:

1. 使用GVM,我已经安装了grails 2.4.0
2. 将grails的默认版本设置为2.4.0
3. 然后在我的项目目录中运行命令set-grails-version到2.4.0,然后更新java以使用oracle jdk 7

我收到以下错误.有什么建议吗？

Answer 1

持有者类已从Grails 2.4.0中删除.更新到最新的插件版本应解决上面的编译错误.

如果您发现最新的插件版本不支持Grails 2.4.0,那么您只需要等到他们发布兼容2.4.0的版本才能升级.

根据个人经验,我知道以下插件具有2.4.0兼容版本:

• 资源
• 邮件
• 石英

但我不确定电子邮件确认或joda-time

Answer 2

已从Grails 2.4.x中删除以下已弃用的类:

org.codehaus.groovy.grails.commons.ApplicationHolder
org.codehaus.groovy.grails.commons.ConfigurationHolder
org.codehaus.groovy.grails.plugins.PluginManagerHolder
org.codehaus.groovy.grails.web.context.ServletContextHolder
org.codehaus.groovy.grails.compiler.support.GrailsResourceLoaderHolder

如果您或您安装的任何插件正在使用这些类,您将收到编译错误.可以通过更新到新插件并使用grails.util.Holders来解决此问题.

例如

application = org.codehaus.groovy.grails.commons.ApplicationHolder.application 

至

application = Holders.grailsApplication
