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：

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

我收到以下错误。有什么建议吗？

Answer 1

来自Grails 2.4.0的持有者类have been removed。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。< / p>

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

以下已弃用的类已从Grails 2.4.x中删除：

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

到

application = Holders.grailsApplication

Answer 3

我认为＆＃34;：quartz：1.0.1＆＃34;和＆＃34;：资源：1.2.8＆＃34;是2.4兼容。据我所知，你遇到的其他插件还没有2.4兼容版本。 2.4并没有很长时间，插件作者仍在努力更新他们的代码。
