1 使用
mvn archetype:generate命令，下载对应的jar和进入Interactive mode。默认情况，上面命令会显示所有的可用的archetype artifact。由于输出的archetype artifact太多，建议使用加Filter参数，我们需要创建一个Archetype ArtifactId为maven-archetype-plugin的project, 所有命令行如下：D:\test>mvn archetype:generate -Dfilter=maven-archetype-plugin

安装提示，填充groupId, artifactId, version, package，即可正常的生成项目。

在目录D:\test\plugin下面，可以看到生成成功的pom.xml和src文件夹。
2 进入D:\test\plugin目录，进行项目的编辑和安装。
运行mvn install，可以查看到安装成功。

同时可以看到生生成的目录：D:\test\plugin\target和里面package的jar和 compile的 class
根据上面的提示或者查看pom.xml文件，我们创建了一个groupId为com.lewi，artifactID为plugin，version为1.0的maven-plugin。
查看本项目的src\main\java\com\lewi\MyMojo.java文件，可以看到此Mojo名为 touch，操作为创建一个新的touch.txt文件，并在文件中写入“touch.txt”.
运行如下命令：
mvn com.lewi:plugin:1.0:touch （version 1.0可以省去）
运行结束后，查看在target文件夹是否新建了文件touch.txt。
4 在pom.xml里面，看到还有一个run-its的profile。此profile中，加入了一个maven-invoker-plugin用来
测试上面生产的touch goal。
使用如下命令尝试运行此profile.
mvn verify -P run-its
出现如下错误：
| Maven invocation failed. Error configuring command-line. Reason: Maven executable not found at: D:\webServers\apache-maven-3.3.3\bin\mvn.bat |
Google出现，发现是新版maven不兼容maven-invoker-plugin。新版的maven安装目录下，mvn主程序名字更改成了maven.cmd，但是maven-invoker-plugin还在寻找maven.bat。
