自定义Maven插件入门

新建一个Maven项目并加入必要依赖

<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>fun.gosuncn</groupId>
    <artifactId>custom-plugin</artifactId>
    <packaging>maven-plugin</packaging>
    <version>1.0</version>

    <dependencies>
        <dependency>
            <groupId>org.apache.maven</groupId>
            <artifactId>maven-plugin-api</artifactId>
            <version>3.5.2</version>
        </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>

建立一个Mojo类

package fun.gosuncn;

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

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

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

    public void execute() {
        getLog().info("hello " + name);
    }

}

直接执行，maven install 即可。

新建一个项目

<?xml version="1.0" encoding="UTF-8"?>
<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/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>fun.gosuncn</groupId>
    <artifactId>common</artifactId>
    <version>1.0</version>

    <build>
        <plugins>
            <plugin>
                <groupId>fun.gosuncn</groupId>
                <artifactId>custom-plugin</artifactId>
                <version>1.0</version>
                <configuration>
                    <name>shanghai</name>
                </configuration>
            </plugin>
        </plugins>
    </build>

</project>

并引用该插件，可以直接执行该插件。
