如何使用Maven使用EJB和WAR构建EAR项目？

我试图用EJB和WAR创建EAR项目，但我遇到了一些问题。 我从以下内容创建了主项目：

在EAR

pom.xml

中，我有：

<modules>
    <module>QCforCC-ejb</module>
    <module>QCforCC-war</module>
</modules>
<packaging>pom</packaging>

---

我强烈建议您了解多模块构建是如何工作的。这本书描写得非常详细

要使用EJB和WAR构建EAR，实际上需要三个模块，分别用于EJB、WAR和EAR。父POM只是将所有的东西放在一起，并具有POM的包装类型

因此，父pom.xml应该如下所示：

<project xmlns="http://maven.apache.org/POM/4.0.0"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
                         http://maven.apache.org/maven-v4_0_0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>org.sonatype.mavenbook.multi</groupId>
    <artifactId>simple-parent</artifactId>
    <packaging>pom</packaging>
    <version>1.0</version>
    <name>Multi Chapter Simple Parent Project</name>

    <modules>
        <module>ejb-module</module>
        <module>war-module</module>
        <module>ear-module</module>
    </modules>
</project>

然后，每个子POM将如下所示：

<project xmlns="http://maven.apache.org/POM/4.0.0"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
