grails 升级 2.4.0 导致 Error Compilation error: startup failed

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，我安装了 grails 2.4.0
2. 将 grails 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将 grails-version 设置为 2.4.0 和 然后更新 java 以使用 oracle jdk 7

我收到以下错误。任何建议为什么？

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该可以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与 2.4.0 兼容的版本才能升级。

根据个人经验，我知道以下插件有2.4.0兼容版本：

• 资源
• 邮件
• 石英

但我不确定 email-confirmation 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。该问题可以通过更新到新插件并改用 grails.util.Holders 来解决。

例如

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

到

application = Holders.grailsApplication

Answer 3

我认为 ":quartz:1.0.1" 和 ":resources:1.2.8" 是 2.4 兼容的。据我所知，您遇到的其他插件还没有 2.4 兼容版本。 2.4 发布时间不长，插件作者仍在努力更新他们的代码。
