Maven自定义插件以及使用

　　简单maven 插件项目的创建以及使用。

　　参考: https://maven.apache.org/guides/plugin/guide-java-plugin-development.html

　　https://maven.apache.org/plugin-tools/index.html

　　官网建议插件名称的起名为-maven-plugin

　　有两种方式，第一种是注解方式；第二种是文档的方式。下面研究其使用。

1. 注解方式

　　参考： https://maven.apache.org/plugin-tools/maven-plugin-tools-annotations/index.html

1. IDEA 新建项目pom 文件如下:

<?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>4.0.0modelVersion>

    <groupId>cn.qz.cloudgroupId>
    <artifactId>my-mvn-pluginartifactId>
    <version>1.0-SNAPSHOTversion>

    <properties>
        <maven.compiler.source>8maven.compiler.source>
        <maven.compiler.target>8maven.compiler.target>
    properties>

    
    <packaging>maven-pluginpackaging>

    <dependencies>
        
        <dependency>
            <groupId>org.apache.maven.plugin-toolsgroupId>
            <artifactId>maven-plugin-annotationsartifactId>
            <version>3.6.2version>
            <optional>trueoptional>
            
        dependency>
        <dependency>
            <groupId>org.apache.mavengroupId>
            <artifactId>maven-coreartifactId>

                <artifactId>maven-plugin-pluginartifactId>
                <version>3.6.2version>
            plugin>
        plugins>
    build>

project>

　　注意打包方式为maven-plugin

2. 标准注解如下:

import org.apache.maven.execution.MavenSession;
import org.apache.maven.plugin.AbstractMojo;
import org.apache.maven.plugin.MojoExecution;
import org.apache.maven.plugin.descriptor.PluginDescriptor;
import org.apache.maven.plugins.annotations.Component;
import org.apache.maven.plugins.annotations.Execute;
import org.apache.maven.plugins.annotations.InstantiationStrategy;
import org.apache.maven.plugins.annotations.LifecyclePhase;
import org.apache.maven.plugins.annotations.Mojo;
import org.apache.maven.plugins.annotations.Parameter;
import org.apache.maven.plugins.annotations.ResolutionScope;
import org.apache.maven.project.MavenProject;
import org.apache.maven.settings.Settings;

/**
 * Mojo Description. @Mojo( name = "" ) is the minimal required annotation.
 * @since 
 * @deprecated 
 */
@Mojo( name = "",
        aggregator = <false|true>,
        configurator = "",
        executionStrategy = "", // (unsupported since Maven 3.0)
        inheritByDefault = <true|false>, // (unsupported since Maven 3.0)
        instantiationStrategy = InstantiationStrategy.,
        defaultPhase = LifecyclePhase.,
        requiresDependencyResolution = ResolutionScope.,
        requiresDependencyCollection = ResolutionScope., // (since Maven 3.0)
        requiresDirectInvocation = <false|true>, // (unsupported since Maven 3.0)
        requiresOnline = <false|true>,
        requiresProject = <true|false>,
        requiresReports = <false|true>, // (unsupported since Maven 3.0)
        threadSafe = <false|true> ) // (since Maven 3.0)
@Execute( goal = "",
        phase = LifecyclePhase.,
        lifecycle = "" )
public class MyMojo
        extends AbstractMojo
{
    /**
     * @since 
     * @deprecated 
     */
    @Parameter( name = "parameter",
            alias = "myAlias",
            property = "a.property",
            defaultValue = "an expression, possibly with ${variables}",
            readonly = <false|true>,
            required = <false|true> )
    private String parameter;

    @Component( role = MyComponentExtension.class,
            hint = "..." )
    private MyComponent component;

    // sample objects taken from Maven API through PluginParameterExpressionEvaluator

    @Parameter( defaultValue = "${session}", readonly = true )
    private MavenSession session;

    @Parameter( defaultValue = "${project}", readonly = true )
    private MavenProject project;

    @Parameter( defaultValue = "${mojoExecution}", readonly = true )
    private MojoExecution mojo;

    @Parameter( defaultValue = "${plugin}", readonly = true ) // Maven 3 only
    private PluginDescriptor plugin;

    @Parameter( defaultValue = "${settings}", readonly = true )
    private Settings settings;

    @Parameter( defaultValue = "${project.basedir}", readonly = true )
    private File basedir;

    @Parameter( defaultValue = "${project.build.directory}", readonly = true )
    private File target;

    public void execute()
    {
        ...
    }
}

　　可以看到有许多内置的属性以及对象，也就是maven 可以直接获取的相关变量。

1. org.apache.maven.plugins.annotations.Mojo 注解如下：

2. org.apache.maven.plugins.annotations.LifecyclePhase 阶段枚举如下：

 */

/**
 * Lifecycle phases.
 * @author Olivier Lamy

 */
public enum LifecyclePhase
{

    VALIDATE( "validate" ),
    INITIALIZE( "initialize" ),
    GENERATE_SOURCES( "generate-sources" ),
    PROCESS_SOURCES( "process-sources" ),
    GENERATE_RESOURCES( "generate-resources" ),

    private final String id;

    LifecyclePhase( String id )
    {
        this.id = id;
    }

    public String id()
    {
        return this.id;
    }

}

3. 新建第一个Mojo

cn.qz.MyMojo

package cn.qz;

import org.apache.maven.execution.MavenSession;
import org.apache.maven.plugin.AbstractMojo;
import org.apache.maven.plugin.MojoExecution;
import org.apache.maven.plugin.descriptor.PluginDescriptor;
import org.apache.maven.plugins.annotations.LifecyclePhase;
import org.apache.maven.plugins.annotations.Mojo;
import org.apache.maven.plugins.annotations.Parameter;
import org.apache.maven.project.MavenProject;
import org.apache.maven.settings.Settings;

import java.io.File;
import java.util.List;

/**
 * Mojo Description. @Mojo( name = "" ) is the minimal required annotation.
 *
 * @since 
 * @deprecated 
 */
@Mojo(name = "mvtest", defaultPhase = LifecyclePhase.COMPILE) // (since Maven 3.0)
public class MyMojo extends AbstractMojo {
    /**
     * @since 
     * @deprecated 
     */
    @Parameter(name = "parameter",
            alias = "myAlias",
            property = "a.property",
            defaultValue = "an expression, possibly with ${variables}",
            readonly = true,
            required = true)
    private String parameter;

    @Parameter
    private List multiParams;

    // sample objects taken from Maven API through PluginParameterExpressionEvaluator

    @Parameter(defaultValue = "${session}", readonly = true)
    private MavenSession session;

    @Parameter(defaultValue = "${project}", readonly = true)
    private MavenProject project;

    @Parameter(defaultValue = "${mojoExecution}", readonly = true)
    private MojoExecution mojo;

    @Parameter(defaultValue = "${plugin}", readonly = true) // Maven 3 only
    private PluginDescriptor plugin;

    @Parameter(defaultValue = "${settings}", readonly = true)
    private Settings settings;

    @Parameter(defaultValue = "${project.basedir}", readonly = true)
    private File basedir;

    @Parameter(defaultValue = "${project.build.directory}", readonly = true)
    private File target;

    public void execute() {
        String groupId = project.getGroupId();
        String artifactId = project.getArtifactId();
        getLog().info("------------------------------< " + groupId + ":" + artifactId + " > start------------------------------");
        getLog().info("target: " + target.getAbsolutePath());
        getLog().info("basedir: " + basedir.getAbsolutePath());
        getLog().info("settings: " + settings);
        getLog().info("plugin: " + plugin);
        getLog().info("mojo: " + mojo);
        getLog().info("project: " + project);
        getLog().info("session: " + session);
        getLog().info("parameter: " + parameter);
        for (int i = 0; i < multiParams.size(); i++) {
            getLog().info("multiParams.get(i): " + multiParams.get(i));
        }
        getLog().info("------------------------------< " + groupId + ":" + artifactId + " > end------------------------------");
    }
}

4. install 生成插件包

5. 另一个项目使用该插件

(1) 使用默认参数:

            <plugin>
                <groupId>cn.qz.cloudgroupId>
                <artifactId>my-mvn-pluginartifactId>
                <version>1.0-SNAPSHOTversion>
                <executions>
                    <execution>
                        <goals>
                            <goal>mvtestgoal>
                        goals>
                    execution>
                executions>
            plugin>

执行compile 后，发现会失败。因为插件中的 multiParams 未校验直接使用，如果不传导致空指针。报错如下：(也就是maven插件内部报错会导致后续流程失败)

Failed to execute goal cn.qz.cloud:my-mvn-plugin:1.0-SNAPSHOT:mvtest (default) on project xm: Execution default of goal cn.qz.cloud:my-mvn-plugin:1.0-SNAPSHOT:mvtest failed.

(2) 修改传递一些参数:

            <plugin>
                <groupId>cn.qz.cloudgroupId>
                <artifactId>my-mvn-pluginartifactId>
                <version>1.0-SNAPSHOTversion>
                <executions>
                    <execution>
                        <goals>
                            <goal>mvtestgoal>
                        goals>
                        
                        <configuration>
                            <myAlias>
                                111222333444
                            myAlias>
                            <multiParams>
                                <multiParam>11multiParam>
                                <multiParam>22multiParam>
                                <multiParam>33multiParam>
                                <multiParam>44multiParam>
                            multiParams>
                        configuration>
                    execution>
                executions>
            plugin>

该项目执行compile日志如下:

[INFO] ------------------------------< cn.qz:xm > start------------------------------
[INFO] target: D:\study\bs-chart\vue-boot-chart\chart-server\target
[INFO] basedir: D:\study\bs-chart\vue-boot-chart\chart-server

[INFO] multiParams.get(i): 33
[INFO] multiParams.get(i): 44
[INFO] ------------------------------< cn.qz:xm > end------------------------------

6. 再加一个Mojo，编译的时候生成一个编译时间文件

package cn.qz;

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

import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.text.SimpleDateFormat;
import java.util.Date;


@Mojo(name = "generate", defaultPhase = LifecyclePhase.COMPILE)
public class GenarateProperties extends AbstractMojo {

    @Parameter(defaultValue = "${project}", readonly = true)
    private MavenProject project;

    @Parameter(defaultValue = "buildtime.txt")
    private String fileName;

    @Parameter(defaultValue = "yyyy-MM-dd HH:mm:ss")
    private String dateFormat;

    public void execute() {
        String groupId = project.getGroupId();
        String artifactId = project.getArtifactId();
        getLog().info("====== " + groupId + ":" + artifactId + " > generate start======");
        // 生成一个properties 文件记录编译时间
        String directory = project.getBuild().getDirectory();
        SimpleDateFormat simpleDateFormat = new SimpleDateFormat(dateFormat);
        String formatedDate = simpleDateFormat.format(new Date());
        File generateFile = new File(new File(directory), fileName);
        try {
            new FileOutputStream(generateFile).write(formatedDate.getBytes());
            getLog().info("write file: " + generateFile.getAbsolutePath());
        } catch (IOException e) {
            getLog().error("write error", e);
            throw new RuntimeException(e);
        }
        getLog().info("====== " + groupId + ":" + artifactId + " > generate end======");
    }

}

7. 测试上面命令

(1) 另一个项目pom 增加插件

            
                cn.qz.cloud
                my-mvn-plugin
                1.0-SNAPSHOT
                
                    
                        
                            generate

执行compile 后查看日志如下:

[INFO] --- my-mvn-plugin:1.0-SNAPSHOT:generate (default) @ xm ---
[INFO] ====== cn.qz:xm > generate start======
[INFO] write file: D:\study\bs-chart\vue-boot-chart\chart-server\target\buildtime.txt
[INFO] ====== cn.qz:xm > generate end======

(2) 修改执行两个goal

            
                cn.qz.cloud
                my-mvn-plugin
                1.0-SNAPSHOT
                
                    
                        
                            generate
                            mvtest
                        
                        
                        
                            
                                11
                                22
                                33
                                44

日志如下:

[INFO] --- my-mvn-plugin:1.0-SNAPSHOT:generate (default) @ xm ---
[INFO] ====== cn.qz:xm > generate start======
[INFO] write file: D:\study\bs-chart\vue-boot-chart\chart-server\target\buildtime.txt

2. 文档方式使用

　　参考： https://maven.apache.org/plugin-tools/maven-plugin-tools-java/index.html

1. pom 如下

<?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"

            plugin>
        plugins>
    build>

project>

2. Mojo 如下

package cn.qz;

import org.apache.maven.plugin.AbstractMojo;
import org.apache.maven.project.MavenProject;

/**
 * 使用文档的方式
 *
 * @goal print
 * @phase compile
 */
public class PrintMojo extends AbstractMojo {


    /**
     * @parameter expression = "${project}"
     */
    private MavenProject project;

    public void execute() {
        String groupId = project.getGroupId();
        String artifactId = project.getArtifactId();
        getLog().info("------------------------------< " + groupId + ":" + artifactId + " > start------------------------------");
        getLog().info("------------------------------< " + groupId + ":" + artifactId + " > end------------------------------");
    }

}

3. 打包后测试：

1. pom 增加

            <plugin>
                <groupId>cn.qz.cloudgroupId>
                <artifactId>my-mvn-pluginartifactId>
                <version>1.0-SNAPSHOTversion>
                <executions>
                    <execution>
                        <goals>
                            <goal>printgoal>
                        goals>
                    execution>
                executions>
            plugin>

2. 执行compile后日志如下

[INFO] --- my-mvn-plugin:1.0-SNAPSHOT:print (default) @ xm ---
[INFO] ------------------------------< cn.qz:xm > start------------------------------
[INFO] ------------------------------< cn.qz:xm > end------------------------------

3. 全局设置

1. 插件项目修改

1. 修改cn.qz.MyMojo 默认阶段绑定为compile

package cn.qz;

import org.apache.maven.execution.MavenSession;
import org.apache.maven.plugin.AbstractMojo;
import org.apache.maven.plugin.MojoExecution;
import org.apache.maven.plugin.descriptor.PluginDescriptor;
import org.apache.maven.plugins.annotations.LifecyclePhase;
import org.apache.maven.plugins.annotations.Mojo;
import org.apache.maven.plugins.annotations.Parameter;
import org.apache.maven.project.MavenProject;
import org.apache.maven.settings.Settings;

import java.io.File;
import java.util.List;

@Mojo(name = "mvtest", defaultPhase = LifecyclePhase.COMPILE) // (since Maven 3.0)
public class MyMojo extends AbstractMojo {
    
    @Parameter(name = "parameter",
            alias = "myAlias",
            property = "a.property",
            defaultValue = "an expression, possibly with ${variables}",
            readonly = true,
            required = true)
    private String parameter;

    @Parameter
    private List multiParams;

    // sample objects taken from Maven API through PluginParameterExpressionEvaluator

    @Parameter(defaultValue = "${session}", readonly = true)
    private MavenSession session;

    @Parameter(defaultValue = "${project}", readonly = true)
    private MavenProject project;

    @Parameter(defaultValue = "${mojoExecution}", readonly = true)
    private MojoExecution mojo;

    @Parameter(defaultValue = "${plugin}", readonly = true) // Maven 3 only
    private PluginDescriptor plugin;

    @Parameter(defaultValue = "${settings}", readonly = true)
    private Settings settings;

    @Parameter(defaultValue = "${project.basedir}", readonly = true)
    private File basedir;

    @Parameter(defaultValue = "${project.build.directory}", readonly = true)
    private File target;

    public void execute() {
        String groupId = project.getGroupId();
        String artifactId = project.getArtifactId();
        getLog().info("------------------------------< " + groupId + ":" + artifactId + " > start------------------------------");
        getLog().info("target: " + target.getAbsolutePath());
        getLog().info("basedir: " + basedir.getAbsolutePath());
        getLog().info("settings: " + settings);
        getLog().info("plugin: " + plugin);
        getLog().info("mojo: " + mojo);
        getLog().info("project: " + project);
        getLog().info("session: " + session);
        getLog().info("parameter: " + parameter);
        if (multiParams != null) {
            for (int i = 0; i < multiParams.size(); i++) {
                getLog().info("multiParams.get(i): " + multiParams.get(i));
            }
        }
        getLog().info("mojo.getLifecyclePhase(): " + mojo.getLifecyclePhase());
        getLog().info("------------------------------< " + groupId + ":" + artifactId + " > end------------------------------");
    }
}

2. 把上面两种形式的三个插件都加到项目，并且修改项目前缀。 pom 修改如下：

<?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>4.0.0modelVersion>

    <groupId>cn.qz.cloudgroupId>
    <artifactId>my-mvn-pluginartifactId>
    <version>2.0-SNAPSHOTversion>

    <properties>
        <maven.compiler.source>8maven.compiler.source>
        <maven.compiler.target>8maven.compiler.target>

                configuration>
            plugin>
        plugins>
    build>

project>

2. 另一个项目

(1) pom引入插件

            <plugin>
                <groupId>cn.qz.cloudgroupId>
                <artifactId>my-mvn-pluginartifactId>
                <version>2.0-SNAPSHOTversion>
            plugin>

(2) IDEAmaven插件查看

(3) 执行：

　　用户可以通过两种方式调用Maven插件目标。第一种方式是将插件目标与生命周期阶段（lifecycle phase）绑定，这样用户在命令行只是输入生命周期阶段而已，例如Maven默认将maven-compiler-plugin的compile目标与compile生命周期阶段绑定，因此命令mvn compile实际上是先定位到compile这一生命周期阶段，然后再根据绑定关系调用maven-compiler-plugin的compile目标。第二种方式是直接在命令行指定要执行的插件目标，例如mvnarchetype:generate 就表示调用maven-archetype-plugin的generate目标，这种带冒号的调用方式与生命周期无关。

1》第一种：

mvn [plugin-name]:[goal-name]

　　该命令的意思是：执行plugin-name插件的 goal-name 目标（或者称为动作）。

测试如下：一种是插件全称，一种是简称

2》第二种：绑定阶段

　　修改pom中插件属性

            <plugin>
                <groupId>cn.qz.cloudgroupId>
                <artifactId>my-mvn-pluginartifactId>
                <version>2.0-SNAPSHOTversion>
                <executions>
                    <execution>
                        
                        <goals>
                            <goal>mvtestgoal>
                        goals>
                    execution>
                executions>
            plugin>

测试一：可以看到默认是compile 阶段走mvtest 任务，也就是我们设置的默认的阶段

测试二：修改阶段为clean，然后执行clean 命令可以看到会走mvtest 任务

pom 中修改阶段为clean 阶段

            <plugin>
                <groupId>cn.qz.cloudgroupId>
                <artifactId>my-mvn-pluginartifactId>

补充：插件生成jar 之后，有相关描述

比如 my-mvn-plugin-2.0-SNAPSHOT.jar!\META-INF\maven\plugin.xml 有相关mojo 以及参数的描述，内容如下
