Maven中dependencyManagement和依赖关系之间的区别

问题：

What is the difference between dependencyManagement and dependencies ? dependencyManagement和dependencies什么区别？ I have seen the docs at Apache Maven web site. 我已经在Apache Maven网站上看到了这些文档。 It seems that a dependency defined under the dependencyManagement can be used in its child modules without specifying the version. 似乎可以在依赖项管理下定义的dependencyManagement在其子模块中使用，而无需指定版本。

For example: 例如：

A parent project (Pro-par) defines a dependency under the dependencyManagement : 父项目（专业人士）在dependencyManagement下定义了一个dependencyManagement ：

<dependencyManagement>
  <dependencies>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>3.8</version>
    </dependency>
 </dependencies>
</dependencyManagement>

Then in the child of Pro-par, I can use the junit: 然后在Pro-par的子级中，我可以使用junit：

  <dependencies>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
    </dependency>
 </dependencies>

However, I wonder if it is necessary to define junit in the parent pom? 但是，我想知道是否有必要在父pom中定义junit吗？ Why not define it directly in the needed module? 为什么不直接在所需的模块中定义它？
