Question

我是J2EE的新手。我在pom.xml中遇到了问题。我的pom.xml是这样的：

<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/xsd/maven-4.0.0.xsd">

<description>New ATOM Project</description>
<parent>
    <groupId>com.bah</groupId>
    <artifactId>atom</artifactId>
    <version>0.0.1-SNAPSHOT</version>
</parent>

我在<parent>标签中有错误。我不知道修复它。我的错误报告是这样的：

 The project com.bah:atom:0.0.1-SNAPSHOT (D:\eclipse_code\J2EE_workspace\atom\pom.xml) has 1 error
 [ERROR]   Non-resolvable parent POM: Could not find artifact com.bah:atom:pom:0.0.1-SNAPSHOT and 'parent.relativePath' points at wrong local POM @ line 45, column 10 -> [Help 2]

请帮帮我。

Answer 1

将<relativePath>参数添加到父<parent>

<parent>
    <groupId>com.bah</groupId>
    <artifactId>atom</artifactId>
    <version>0.0.1-SNAPSHOT</version>
     <relativePath>../pathtopom/my-parent-pom.xml</relativePath>
</parent>

或之前安装父pom 执行
mvn clean install -f my-parent-pom.xml

Answer 2

您确定需要parent和modules标签吗？通常不需要任何此标记，除非您希望一个pom文件一次构建所有模块（'maven reactor'http://maven.apache.org/guides/mini/guide-multiple-modules.html）使用dependency并抛弃父子结构。

在pom.xml中找不到工件问题
