maven自定义插件 mvn install时报错 Error extracting plugin descriptor: 'No mojo definitions wer e found for

自定义一个插件，继承AbstractMojo，实现execute方法，引入该自定义插件，执行mvn install，报错

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-plugin-plugin:3.2:descriptor (default
-descriptor) on project maven-project: Error extracting plugin descriptor: 'No mojo definitions wer
e found for plugin: com.gupao:maven-project.' -> [Help 1]
 

因为还需要加一个maven-plugin-plugin来生成descriptor

再次运行，就不会报错了

found plugin Maven for 插件 error install
