java - 将 pom.xml 与父级合并

Question

我继承了一个maven项目，它的结构有点困惑。父文件夹中有一个 home pom.xml，子文件夹中有另一个。这种结构有点令人困惑，因为父级除了管理子级之外什么也没有。

有没有办法将两者合并？我尝试手动执行此操作但失败了。我认为我的问题在于第谷和 eclipse 插件。

这是子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> 

父级是:

<?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

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

然后，删除(或移动)pom.xml把所有的东西都搬进去子文件夹到父文件夹。 (如果您不删除它，它可能会覆盖父级中的 pom.xml。)
