Grails Java 8开发模式支持

Question

由于Java 7现在不再公开维护，Grails2.4.X对Java 8的支持在重新加载时处于开发模式(崩溃)边缘。，我想知道在我迁移之前，是否有人在Java8dev模式Grails2.5或Grails 3上有更好的运气？

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

我的错误：

Answer 1

我的建议，简单，加载和清晰:迁移(或升级真的)，不要回头。

The our .我们在2014年10月与Grails2.3和JDK7一起启动了一个GG项目，一直持续到2.5.1和Java 8。然后我们开始看到地面在我们脚下移动，Grails 3和Gradle都在那里，而我们却停滞不前。.2，.3，.4，.5.而我们站在玻璃后面看着。Stackoverflow在Grails 2上的水流变得越来越薄和干燥的时候，它的新特性和问题都在嗡嗡作响。这很伤人，我认为你现在肯定在经历这个过程。

The How.您最大的问题(如果不是和唯一的问题)是您在BuildConfig文件中得到了什么-插件。在这个体面升级页面中，除了BuildConfig.groovy到build.gradle步骤之外，您几乎可以盲目地遵循其他所有内容。例如，必须更改处理spring安全性和web服务的插件，如果您在视图中嵌入了ajax组件(如submitToRemote和remoteFunction)，那么您需要考虑重新构建纯jQuery和ajax调用中的所有插件，或者只是添加ajax插件，使所有这些组件都能像以前那样工作。

The Steps.

1. 对Gradle有一点了解，并严重依赖斯代克曼
2. IDE的IntelliJ 15
3. 创建Grails 3项目
4. 如果spring安全性是您的插件之一，不要从您的旧项目中复制代码，在本地使用快速启动集成插件机制
5. 对于旧的ajax组件，您可以在build.gradle中添加以下一行，所有这些都应该像它们那样工作，尽管GG团队建议不要这样做。compile 'org.grails.plugins:ajax-tags:1.0.0.RC1'
6. 使用的Web服务？遵循这个职位的步骤，看看您应该如何制作插件包以及如何使用服务。
7. 是的，现在遵循上面提到的升级页面中的步骤，但是要注意每个插件。支持的是在此页中。

其他重要的步骤？添加作为评论或直接到此列表，以使这样的任务更容易，更容易的G2‘在那里。我会继续编辑这个。
