创建一个maven项目
artifactId的命名
{执行域名}-maven-plugin

• 修改打包方式

<packaging>maven-plugin</packaging>

• 添加依赖包

        <dependency>
            <groupId>org.apache.maven</groupId>
            <artifactId>maven-plugin-api</artifactId>
            <version>2.0</version>
        </dependency>
        <dependency>
            <groupId>org.apache.maven.plugin-tools</groupId>
            <artifactId>maven-plugin-annotations</artifactId>
            <version>3.2</version>
        </dependency>

• 测试代码示例

@Mojo(name = "app")//执行实例名
public class App extends AbstractMojo {

    public void execute() throws MojoExecutionException, MojoFailureException {
        this.getLog().info("app . . .");
    }

}

• 从测试项目中天加上面的测试

<plugin>
                <groupId>maven</groupId>
                <artifactId>demo-maven-plugin</artifactId>
                <version>0.0.1-SNAPSHOT</version>
            </plugin>

• 执行代码测试
  mvn {执行域名}:{该域下的执行实例名}

 mvn demo:app

$ mvn demo:app
