插件命名公约和 Apache Maven 商标

maven-<someplugin>-plugin 为官方的命名模式(Maven 的什么插件)

<yourplugin>-maven-plugin 非官方的插件命名模式（你的Maven插件）

1.根据骨架生成项目

mvn archetype:generate -DgroupId=cn.zno.plugin -DartifactId=hello-maven-plugin -DarchetypeGroupId=org.apache.maven.archetypes -DarchetypeArtifactId=maven-archetype-plugin

前两个参数是设置自己的项目信息

后两个参数是指定具体的原型

点击查看所有参数

2. 遭遇问题

Plugin execution not covered by lifecycle configuration: org.apache.maven.plugins:maven-plugin-plugin:3.2:descriptor (execution: default-descriptor, phase: generate-resources)

解决办法：安装 e2m 插件。点击查看

3.新建自己的项目

7.设置参数

修改GreetingMojo.java 文件

package cn.zno.plugin;

import org.apache.maven.plugin.AbstractMojo;

import org.apache.maven.plugin.MojoExecutionException;

import org.apache.maven.plugins.annotations.Mojo;

import org.apache.maven.plugins.annotations.Parameter;

/**

 *

 */

@Mojo(name = "sayhi")

public class GreetingMojo extends AbstractMojo {

    @Parameter( property = "sayhi.greeting", defaultValue = "Hello World!" )

    private String greeting;

    public void execute() throws MojoExecutionException {

        getLog().info(greeting);

    }

}

修改插件测试项目
