maven-assembly-plugin封装

1. 修改pom.xml

<build>
        <resources>
            <!--资源过滤*.properties到target/classes下-->
            <resource>
                <includes>
                    <include>**/*.properties</include>
                    <include>log4j.xml</include>
                </includes>
                <directory>src/main/resources</directory>
                <filtering>true</filtering>
            </resource>
            <!--复制除 *.properties 到target/classes/下，不做资源过滤-->
            <resource>
                <excludes>
                    <exclude>**/*.properties</exclude>
                </excludes>
                <directory>src/main/resources</directory>
                <filtering>false</filtering>
            </resource>
            <!--复制除 *.properties 到target/classes/assembly-conf下，不做资源过滤-->
            <resource>
                <excludes>
                    <exclude>**/*.properties</exclude>
                </excludes>
                <directory>src/main/resources</directory>
                <filtering>false</filtering>
                <targetPath>assembly-conf</targetPath>
            </resource>
            <!--资源过滤*.properties,log4j.xml到assembly-conf，最终由assembly插件复制到conf目录下-->
            <resource>
                <includes>
                    <include>**/*.properties</include>
                    <include>log4j.xml</include>
                </includes>
                <directory>src/main/resources</directory>
                <filtering>true</filtering>
                <targetPath>assembly-conf</targetPath>
            </resource>
        </resources>
        <plugins>
            <!--package时打出可执行的tar.gz-->
            <plugin>
                <artifactId>maven-assembly-plugin</artifactId>
                <configuration>
                    <descriptor>src/main/assembly/assembly.xml</descriptor>
                </configuration>
                <executions>
                    <execution>
                        <id>make-assembly</id>
                        <phase>package</phase>
                        <goals>
                            <goal>single</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
        </plugins>

    </build>

2、src/main/assembly/assembly.xml

<assembly>
    <id>assembly</id>
    <formats>
        <format>dir</format><!-- 2012-8-23 update -->
        <format>zip</format>
    </formats>
    <includeBaseDirectory>false</includeBaseDirectory> <!--2012-8-23 modify true to false-->
    <fileSets>
        <fileSet>
            <directory>src/main/assembly/bin</directory>
            <outputDirectory>bin</outputDirectory>
            <fileMode>0755</fileMode>
        </fileSet>
        <fileSet>
            <directory>target/classes/assembly-conf</directory>
            <outputDirectory>conf</outputDirectory>
            <fileMode>0644</fileMode>
        </fileSet>
    </fileSets>
    <dependencySets>
        <dependencySet>
            <outputDirectory>lib</outputDirectory>
            <useProjectArtifact>true</useProjectArtifact>
            <scope>runtime</scope>
        </dependencySet>
    </dependencySets>
</assembly>

简单解释一下：

    1) format
    format=zip设置打包的最终文件格式为zip.
    支持的其他格式还有gz,tar,tar.gz,tar.bz2。

    2)  fileset
  
    <fileSet>
            <directory>src/main/bin</directory>
            <outputDirectory>/</outputDirectory>
    </fileSet>
 
    将src/main/bin目录下的文件打包到根目录(/)下.

<fileSet>
            <directory>src/main/config</directory>
            <outputDirectory>config</outputDirectory>
</fileSet>

    将src/main/config目录下的文件打包到config下.

    3) dependencySets

    <dependencySet>
            <outputDirectory>lib</outputDirectory>
            <scope>runtime</scope>
    </dependencySet>

    将scope为runtime的依赖包打包到lib目录下。

详细的语法不介绍了，请参考官方指南，有非常详尽的说明：Assembly Descriptor Format reference
