maven 插件开发

1.新建maven插件开发工程

2.修改pom文件内容为如下：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <groupId>org.example</groupId>
  <artifactId>demo-maven-plugin</artifactId>
  <packaging>maven-plugin</packaging>
  <version>1.0-SNAPSHOT</version>
  <name>demo-maven-plugin Maven Mojo</name>
  <url>http://maven.apache.org</url>
  <dependencies>
    <dependency>
      <groupId>org.apache.maven</groupId>
      <artifactId>maven-plugin-api</artifactId>
      <version>2.0</version>
    </dependency>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>3.8.1</version>
      <scope>test</scope>
    </dependency>
    <dependency>
      <groupId>org.apache.maven.plugin-tools</groupId>
      <artifactId>maven-plugin-annotations</artifactId>
      <version>3.5.2</version>
      <scope>provided</scope>
    </dependency>
  </dependencies>
  <build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-plugin-plugin</artifactId>
        <version>3.5.2</version>
      </plugin>
    </plugins>
  </build>
</project>

 3.新建demo类

package org.example;

 */

import org.apache.maven.plugin.AbstractMojo;
import org.apache.maven.plugin.MojoExecutionException;
import org.apache.maven.plugin.MojoFailureException;
import org.apache.maven.plugins.annotations.Mojo;
import org.apache.maven.plugins.annotations.Parameter;

/**
 * @author buhao
 * @version DemoMojo.java, v 0.1 2020-03-30 22:51 buhao
 */
@Mojo(name = "hello")
public class DemoMojo extends AbstractMojo {

    @Parameter(name = "name", defaultValue = "kiwi")
    private String name;

    public void execute() throws MojoExecutionException, MojoFailureException {
        getLog().info("hello " + name);
    }
}

4.将插件开发后的jar包添加到工程pom文件中

<plugin>
  <groupId>org.example</groupId>
  <artifactId>demo-maven-plugin</artifactId>
  <version>1.0-SNAPSHOT</version>
  <configuration>
    <name>你好</name>
  </configuration>
</plugin>

4.idea右边点击maven进行测试

5.测试结果如下：

 

6.总结

必须继承 AbstractMojo 该类重写execute类
