Maven生命周期和插件MOJO

一、插件命名

You will typically name your plugin <yourplugin>-maven-plugin.

Calling it maven-<yourplugin>-plugin (note “Maven” is at the beginning of the plugin name) is strongly discouraged since it’s a reserved naming pattern for official Apache Maven plugins maintained by the Apache Maven team with groupId org.apache.maven.plugins. Using this naming pattern is an infringement of the Apache Maven Trademark.

其中yourplugin是你的插件名，可以通过mvn yourplugin:goal调用指定MOJO。

二、Maven生命周期和MOJO

1）Maven三个独立生命周期

参考：官网-maven生命周期

2）Maven生命周期和插件绑定关系

参考：官网-Maven常用插件的默认绑定

三、MOJO执行的两个方式

1）执行Maven生命周期

$ mvn phase

2）直接调用插件

语法格式：

# 完全限定名:goal
$ mvn [groupId]:[artifactId]:[version]:[goal]
# 插件名:goal
$ mvn [pluginName]:[goal]

示例：

$ mvn org.apache.maven.plugins:maven-dependency-plugin:2.8:tree
$ mvn dependency:tree
