maven之EAR的Grails Maven包装

think 2025年05月04日编程语言 223 0

在Grails 2.2.x之前，我已经能够使用Maven创建grails项目并将其包含在Maven Ear项目中，并且一切正常。 Grails 2.2.x中新的pom.xml已将打包类型更改为“grails-app” ，这引起了一些新问题。旧包装类型是“ war ”，效果很好。

有人遇到过同样的问题吗？有解决方法吗？

这是我的项目的结构。

这是尝试构建项目的结果

请您参考如下方法:

为此，您可以将grails应用程序重新发布为 war 构件。为此，请在Grails应用程序pom中添加以下内容。然后在EAR pom中引用新的 war Artifact 。
