maven生命周期以及插件goal介绍

maven生命周期分为三套，分别是clean、default和site,每个生命周期相互独立，互不影响。每个生命周期包含一些阶段（phase）

clean生命周期主要是用来清理项目
default生命周期主要是构建项目
site生命周期主要是建立项目站点

clean生命周期包含phase如下：

pre-clean执行一些清理前需要完成的工作。
clean清理上一次构建生成的文件。
post-clean执行一些清理后需要完成的工作。

default生命周期包含phase如下：

validate
initialize
generate-sources
process-sources 处理资源文件，对变量进行替换工作
generate-resources
process-resources 复制resource文件到输出目录
compile 编译java文件并复制到输出目录
process-classes
generate-test-sources
process-test-sources 处理测试资源文件，对变量进行替换工作
generate-test-resources
process-test-resources 复制测试resource文件到输出目录
test-compile 编译测试java文件并复制到输出目录
process-test-classes
test 执行测试用例
prepare-package
package 项目打包，比如Jar包等
pre-integration-test
integration-test
post-integration-test
verify 打包之后，install到本地仓库之前阶段，比如maven-source-plugin的goal:jar-no-fork就是绑定在这个阶段
install 将包安装到本地仓库
deploy 将包复制到远程仓库。

site生命周期包含phase如下：

pre-site
site
post-site
site-deploy

maven的核心仅仅定义了生命周期，具体的任务是交由插件来完成的，比如执行mvn clean的时候，实际上就是下载插件maven-clean-plugin，如果项目里声明了插件版本，就用项目里的插件版本，否则用超级pom里的插件版本。

每个插件执行任务都是要跟生命周期绑定的，mvn clean实际上是绑定了clean生命周期的clean阶段，跟阶段绑定都是由插件的目标(goal)来完成的，mvn clean 默认的目标是clean，详细写法：mvn clean:clean,具体哪些插件有哪些目标可以参考maven官网有详细的指南。

还有哪些默认绑定

下面执行一段mvn clean install，可以很清楚的对应。

另外除了内置的默认绑定，还可以自定义绑定，比如maven-source-plugin自定义绑定放在executions，可以绑定很多个阶段分别在execution。

<plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-source-plugin</artifactId>
        <version>2.1.1</version>
        <executions>
            <execution>
                <id>attach-sources</id>
                <phase>package</phase>
                <goals>
                    <goal>jar-no-fork</goal>
                </goals>
            </execution>
        </executions>
</plugin>
