Maven常用插件

一、基础知识

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mvn archetype: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。

插件目标（goal）可以附着在生命周期阶段上。随着Maven沿着生命周期的阶段移动，它会执行附着在特定阶段上的目标。每个阶段可能绑定了零个或者多个目标。

六、org.codehaus.mojo:properties-maven-plugin

介绍：mvn help:describe -Dplugin=properties

在java工程中，存在某个xxx.xml、xxx.properties。。。。资源文件。其中资源文件的参数针对不同的环境（开发、测试、生产）需要使用不同的参数值。

properties-maven-plugin插件实现该需求的方式是：

通过properties-maven-plugin插件读取动态参数的字典数据文件(dev.properties、prod.properties。。。)，在maven构建的环节中进行参数的替换。

例：

（1）应用中需要被动态替换参数的资源文件：

src/resources/test.properties

[html] view
plaincopy

durl=${url}

src/resources/test.xml

[html] view
plaincopy

<test>

<url>${url}</url>

</test>

（2）针对不同环境进行构建的参数字典文件

deploy_env/resources/dev.properties

[html] view
plaincopy

url=http://www.baidu.com

deploy_env/resources/prod.properties

[html] view
plaincopy

url=http://www.qq.com

（3）pom文件：properties-maven-plugin.xml

[html] view
plaincopy

<properties>

<param>dev</param>

</properties>

<build>

<resources>

<resource>

<directory>src/resources</directory>



<filtering>true</filtering>

</resource>

</resources>

<plugins>

<plugin>

<groupId>org.codehaus.mojo</groupId>

<artifactId>properties-maven-plugin</artifactId>

<version>1.0-alpha-1</version>

<executions>

<execution>

<phase>initialize</phase>

<goals>

<goal>read-project-properties</goal>

</goals>

<configuration>

<files>

<file>deploy_env/resources/${param}.properties</file>

</files>

</configuration>

</execution>

</executions>

</plugin>

</plugins>

</build>

执行构建命令：

mvn -f properties-maven-plugin.xml install （默认使用dev.properties文件）

mvn -f properties-maven-plugin.xml install -Dparam=prod

构建后，在工程target文件夹下的test.properties、test.xml文件中的动态参数已被替换
