Question

由于Java 7现在不再被公开维护，并且Grails 2.4.X对Java 8的支持在重新加载时在dev-mode 中是边缘的（崩溃）。 我想知道在迁移之前是否有人在Java 8 dev-mode Grails 2.5或Grails 3 方面有更好的运气？

理论上，很多东西都是通过迁移到更新的Spring Boot（即grails 3）来升级的。

我的错误：

我的建议，简单，负载和明确：迁移（或真正升级），不要回头。

为什么。 我们在2014年10月开始了一个GG项目，Grails 2.3和JDK7，一直到2.5.1和Java 8.然后我们开始看到我们脚下的地面转移Grails 3和Gradle在那里我们停滞不前。 Grails 3.1，.2，.3，.4，.5 ......而我们站在玻璃后面看。 Stackoverflow在新的功能和问题上嗡嗡作响，而Grails 2上的水流变得更薄更干燥。它很痛苦，我认为你现在必须经历这个。

如何。 你最大的问题（如果不是也是唯一的问题）就是你在BuildConfig文件中遇到的问题 - 插件。除了BuildConfig.groovy到build.gradle步骤之外，您可以在decent Upgrade page中盲目跟踪其他所有内容。例如，必须更改处理spring安全性和Web服务的插件，如果你在视图中嵌入了ajax组件（如submitToRemote和remoteFunction），那么你需要考虑在纯jQuery和ajax调用中重建所有这些组件。只需为所有这些组件添加ajax插件即可正常工作。

步骤。

稍微了解Gradle并严重依赖sdkman
IDE的IntelliJ 15
创建Grails 3项目
如果Spring安全性是您的插件之一，请不要从旧项目中复制代码，使用quickstart
对于较旧的ajax UI组件，您可以将以下行添加到build.gradle，并且所有内容都应该像他们一样工作，尽管GG团队建议不要这样做。 compile 'org.grails.plugins:ajax-tags:1.0.0.RC1'
使用了哪些网络服务？按照steps in this post查看如何制作插件以及使用服务
是的，现在按照上面提到的升级页面中的步骤进行操作密切关注每一个插件。受支持的文件位于this page。

其他重要步骤？添加为评论或直接添加到此列表中，以使G2的用户更轻松，更轻松地完成此任务。我会继续编辑这个。
