在Grails 2.2.x之前，我已经能够使用Maven创建grails项目，并将它们包含在Maven Ear项目中，一切正常。 Grails 2.2.x中的新pom.xml已将包装类型更改为“grails-app”，这会导致一些新问题。旧的包装类型是“战争”，并且工作正常。
有没有人遇到同样的问题？有解决方法吗？
这是我项目的结构。

要完成这项工作，您可以将grails应用程序重新发布为战争工件。要在Grails应用程序pom中执行此操作，请添加以下内容。然后在你的EAR pom中引用新的战争神器。
<project>
<modelVersion>4.0.0</modelVersion>
<artifactId>testGrailsApp</artifactId>
<packaging>grails-app</packaging>
<parent>
<artifactId>testProject</artifactId>
<groupId>test</groupId>
<version>0.1-SNAPSHOT</version>
</parent>
<properties>
<grails.version>2.2.1</grails.version>
</properties>
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-install-plugin</artifactId>
<executions>
<execution>
<id>create-war-pom</id>

<groupId>${groupId}</groupId>
<version>${version}</version>

我认为你只需要两个简单的修改：
TestGrailsApp pom.xml 从父pom继承后添加应用程序的工件信息
<parent>
<groupId>test</groupId>
<artifactId>testProject</artifactId>
<version>0.1-SNAPSHOT</version>
</parent>
<groupId>test</groupId>
<artifactId>testGrailsApp</artifactId>
<packaging>grails-app</packaging>
<version>0.1</version>
<name>testGrailsApp</name>
<description>testGrailsApp</description>
<properties>
<grails.version>2.2.1</grails.version>
</properties>
编辑TestEar pom.xml如下（将类型添加为war而不是grails-app）
<dependencies>
<dependency>
<groupId>test</groupId>
<artifactId>testGrailsApp</artifactId>
<version>0.1-SNAPSHOT</version>
<type>war</type>
</dependency>
</dependencies>
你完成了。!!
注意：我执行了“grails create-pom test”来创建应用程序的pom.xml
原因： TestProject（家长） - TestGrailsApp（Child） - TestEar（儿童）
Grails maven插件隐含地在生命周期中构建战争。一旦战争文件建成，你需要通知耳朵抓住战争并用它将它包装在耳中。 Maven-ear-plugin完成剩下的工作。
