一、parent

<parent>元素包含定位此项目将从中继承的父项目所需的信息。注意：此元素的子元素不是插值的，必须作为文字值给定。

Element	Type	Description
groupId	String	要从中继承的父项目的组id。
artifactId	String	要从中继承的父项目的项目id。
version	String	要继承的父项目的版本。
relativePath	String	签出中父pom.xml文件的相对路径。如果未指定，则默认为/pom.xml。Maven首先在文件系统上的这个位置查找父POM，然后在本地存储库中查找，最后在远程repo中查找。relativePath允许您选择不同的位置，例如，当您的结构是平的，或者更深而没有中间父POM时。但是，组ID、工件ID和版本仍然是必需的，并且必须与给定位置的文件匹配，否则它将恢复到POM的存储库。此功能仅用于增强该项目的本地签出中的开发。如果您想禁用该功能并始终从存储库中解析父POM，请将该值设置为空字符串。 默认值为：/pom.xml .
