Maven 默认插件以及功能

Maven 默认插件

已知 Maven 使用 plugin 来执行实际操作的，在默认情况下，Maven 会绑定以下几个插件来完成基本操作。

plugin function life cycle phase
maven-clean-plugin 清理上一次执行创建的目标文件 clean
maven-resources-plugin 处理源资源文件和测试资源文件 resources,testResources
maven-compiler-plugin 编译源文件和测试源文件 compile,testCompile
maven-surefire-plugin 执行测试文件 test
maven-jar-plugin 创建 jar jar
maven-install-plugin 安装 jar，将创建生成的 jar 拷贝到 .m2/repository 下面 install
maven-deploy-plugin 发布 jar deploy
如果针对各个 plugin 有特殊配置的话，需要显示指定 plugin 和 属性配置。

样例

举个��：创建一个空的 maven 项目 HelloWorld，pom.xml 文件不包含任何 plugin。

<?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>com.meituan.log</groupId>    <artifactId>HelloWorld</artifactId>    <version>1.0-SNAPSHOT</version>    <packaging>jar</packaging>    <dependencies>        <dependency>            <groupId>org.apache.hadoop</groupId>            <artifactId>zookeeper</artifactId>            <version>3.3.1</version>        </dependency>        <dependency>            <groupId>org.apache.hadoop</groupId>            <artifactId>zookeeper</artifactId>            <version>3.3.1</version>        </dependency>    </dependencies></project>

下面是执行 mvn clean install 产生的执行日志，通过日志可以看到每个步骤都显示 plugin 名称，版本号，生命周期阶段，执行操作等。

maven-clean-plugin:2.5:clean (default-clean)
maven-resources-plugin:2.6:resources (default-resources)
maven-compiler-plugin:3.1:compile (default-compile)
