Maven查看模块依赖图

当进行模块重构和重组时，需要查看当前模块间的依赖关系。以下说明了两个常用的方式。

一、IDEA旗舰版-模块依赖图

https://www.jetbrains.com/help/idea/project-module-dependencies-diagram.html

1. From the main menu, select View | Tool Windows | Project (Alt+1), select an item (project/module) for which you want to view a diagram.
2. Right-click the selected item and from the context menu, select Diagram | Show Diagram (or press Ctrl+Alt+Shift+U).
3. From the list that opens, select a type of the diagram you want to create.

二、maven-graph-plugin

• 源码：https://github.com/fusesource/mvnplugins/tree/master/maven-graph-plugin

• 命令：mvn org.fusesource.mvnplugins:maven-graph-plugin:1.45:reactor -Dhide-external=true -Dgraph.direction=BT

• 配置项：参考源码ProjectMojo.java

• 示例：git@github.com:apache/maven.git根目录执行命令后得到下图：
