合并 pom.xml 与 parent 的合并

Question

我继承了一个maven项目，它的结构有点混乱。 parent 文件夹中有一个主页 pom.xml，child 文件夹中还有一个。这个结构有点混乱，因为 parent 除了管理 child 之外什么也没有。

有没有办法合并两者？我尝试手动这样做但失败了。我认为我的问题出在 Tycho 和 eclipse 插件上。

这里是 child pom.xml:

<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">
  <modelVersion>4.0.0</modelVersion>
  <parent>
    <groupId>my.project</groupId>
    <artifactId>my.project.foo.parent</artifactId>
    <version>2.4.0</version>
  </parent>
  <artifactId>my.project.foo</artifactId>
  <packaging>eclipse-plugin</packaging>
</project>

而 parent 是：

<?xml version="1.0" encoding="UTF-8"?>
<project>
  <modelVersion>4.0.0</modelVersion>
  <groupId>my.project</groupId>
  <artifactId>my.project.foo.parent</artifactId>
  <version>2.4.0</version>
  <packaging>pom</packaging>

Answer 1

在父pom.xml改变 <packaging>pom</packaging> 至 <packaging>eclipse-plugin</packaging>
和 <artifactId>my.project.foo.parent</artifactId> 到 <artifactId>my.project.foo</artifactId>

然后，擦除（或移动）子节点中的pom.xml，并移动所有内容子文件夹到父文件夹。（如果不删除它，它可能会覆盖父级中的 pom.xml。）
