java – 父pom.xml的包装无效,必须是“pom”,而是“ear”

有人可以建议我一个解决方案,但有以下例外.我将要创建一个多模块项目.

父项目名称为LOGICBACKEND
子项目名称是DBAccess

我需要有一个LOGICBACKEND的耳机文件,该文件应包含DBAccess prjoects jar文件.

当我运行mav clean install -P Developer时,我得到以下异常.

[ERROR]The project com.project1.Database:DBAccess:1.0-SNAPSHOT (C:\Project1\DBAccess\pom.xml) has 1 error
[ERROR]Invalid packaging for parent POM com.project1.logic:LOGIC:1.0-SNAPSHOT (C:\Project1\pom.xml),must be "pom" but is "ear" @ com.project1.logic:LOGIC:1.0-SNAPSHOT,C:\Project1\pom.xml,line 6,column 13

这是我的父pom.xml的一部分

<modelVersion>4.0.0</modelVersion>
<groupId>com.project1.logic</groupId>
<artifactId>LOGICBACKEND</artifactId>
<packaging>ear</packaging>
<version>1.0-SNAPSHOT</version>

这就是孩子pom.xml的样子

<groupId>com.project1.logic</groupId>
<artifactId>DBAccess</artifactId>
<packaging>ejb</packaging>
<name>DBAccess</name>
<version>1.0-SNAPSHOT</version>
 
<parent>
    <groupId>com.project1.logic</groupId>
    <artifactId>DBAccess</artifactId>
    <version>1.0-SNAPSHOT</version>
    <relativePath>../pom.xml</relativePath>
</parent>

有人帮我在这里了解这里出了什么问题.

提前感谢任何帮助

解决方法

这个简单的设置是一个很好的开始.
