maven-assembly-plugin 配置技巧

一、有时web工程的静态文件(image/css/js)希望独立部署，需要针对静态内容打包。可通过以下配置:


<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-assembly-plugin</artifactId>
    <version>2.2</version>
    <executions>
      <execution>
        <id>make-assembly</id>
        <phase>package</phase>
        <goals>
          <goal>single</goal>
        </goals>
        <configuration>
          <descriptors>
            <descriptor>src/assemble/statics-zip.xml</descriptor>
          </descriptors>
        </configuration>
      </execution>
    </executions>
</plugin>

当然，另外还需手工编写相应的src/assemble/statics-zip.xml文件，以配置zip文件中的内容:



<?xml version="1.0" encoding="UTF-8"?>
<assembly xmlns="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.0"  
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.0 http://maven.apache.org/xsd/assembly-1.1.0.xsd">
    <id>statics</id>
    <formats><format>zip</format></formats>
    <includeBaseDirectory>false</includeBaseDirectory>
    <fileSets>
        <fileSet>
          <directory>${basedir}/src/main/webapp/statics-gen</directory>
          <outputDirectory>statics</outputDirectory>
        </fileSet>
    </fileSets>
</assembly>

二、 当web工程的静态内容独立部署时，相应的war中可以不再需要包含相应的静态内容。可通过以下配置排除:


    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-war-plugin</artifactId>
        <version>2.1.1</version>
<configuration>
  <packagingExcludes>statics/**,statics-gen/**</packagingExcludes>
</configuration>
    </plugin> 

三、有时希望在jar/war包中，写入当前的SVN revision ，以准确对应SVN中的版本。可先通过以下配置获取当前SVN 版本号:


    <plugin>
        <groupId>com.google.code.maven-svn-revision-number-plugin</groupId>
        <artifactId>maven-svn-revision-number-plugin</artifactId>
        <version>1.6</version>
<executions>
    <execution>
        <goals>
            <goal>revision</goal>
        </goals>
    </execution>
</executions>
<configuration>
    <entries>
        <entry>
            <prefix>SVN</prefix>
        </entry>
    </entries>
</configuration>
    </plugin>

再将SVN版本号写入war包中:


    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-war-plugin</artifactId>
        <version>2.1.1</version>
<configuration>
  <archive>
    <manifestEntries>
      <SVN-Revision>${SVN.revision}</SVN-Revision>
    </manifestEntries>
  </archive>
</configuration>
    </plugin>
