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，并且一切正常。Grails 2.2.x 中的新 pom.xml 已将打包类型更改为“grails-app”，这导致了一些新问题。旧的包装类型是“战争”，效果很好。

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。

TestProject 
 |-pom.xml 
 |-TestEar 
 |  \pom.xml 
 |-TestGrailsApp 
    \pom.xml

测试项目 pom.xml

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。然后在您的 EAR pom 中引用新的战争工件。

<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>
                        <phase>install</phase>
                        <goals>
                            <goal>install-file</goal>
                        </goals>
                        <configuration>
                            <artifactId>${project.parent.artifactId}War</artifactId>
                            <groupId>${groupId}</groupId>
                            <version>${version}</version>
                            <file>${build.directory}/${artifactId}-${version}.war</file>
                            <generatePom>true</generatePom>
                            <packaging>war</packaging>
                        </configuration>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>
</project>

我认为您只需要两个简单的修改：

  1. TestGrailsApp pom.xml 添加app继承自父pom后的artifact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>

  2. 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>

你完了。！！

注意：我执行了“grails create-pom test”来创建应用程序的 pom.xml

原因：TestProject(Parent) -- TestGrailsApp (Child) -- TestEar (Child)

Grails maven 插件在生命周期中隐式构建战争。一旦构建了war文件，您只需要通知ear pom来获取war并使用它来将其打包到ear中。Maven-ear-plugin 完成剩下的工作。
