Maven插件开发简明教程(1)

新建普通maven工程

注意artifactId的命名为：xxx-maven-plugin, packaging为maven-plugin.

<groupId>org.example</groupId>
    <artifactId>my123-maven-plugin</artifactId>
    <version>1.0-SNAPSHOT</version>
    <packaging>maven-plugin</packaging>

引入依赖

<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>

创建自定义的Mojo类

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;

@Mojo(name = "hello")
public class HelloMojo extends AbstractMojo {

    @Parameter
    private String name;

    @Override
    public void execute() throws MojoExecutionException, MojoFailureException {
        getLog().info("hello, mojo.");
        System.out.println(name);
    }
}

注意此处配置了参数name，后面可以看到具体的参数配置位置。

安装插件

maven install

新建maven工程并引入自定义插件

<build>
        <plugins>
            <plugin>
                <groupId>org.example</groupId>
                <artifactId>my123-maven-plugin</artifactId>
                <version>1.0-SNAPSHOT</version>
                <configuration>
                    <name>alice</name>
                </configuration>
            </plugin>
        </plugins>
    </build>

配置了参数name

运行插件
