1. pom 中添加assembly 插件

要使用assembly 进项编译打包， 首先主要在pom 中的build中添加插件信息， 具体如图下所示：

<build> <finalName>${project.artifactId}</finalName> <sourceDirectory>src/main/java</sourceDirectory> <resources> <resource> <directory>src/main/resources</directory> <filtering>true</filtering> <includes> <include>**/*.xml</include> <include>**/*.properties</include> </includes> </resource> <resource> <directory>${profile.dir}</directory> <filtering>true</filtering> </resource> </resources> <plugins> <!-- compiler插件参数设置，指定编码 --> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>3.1</version> <configuration> <source>1.8</source> <target>1.8</target> <encoding>utf-8</encoding> </configuration> </plugin> <!-- 这个插件是关键 --> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-assembly-plugin</artifactId> <configuration> <!-- 这个是assembly 所在位置 --> <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. 创建assembly文件夹和assembly.xml文件

创建assembly文件夹和assembly.xml文件, 这个样子创建主要是规范。

在pom 中已经介绍assembly.xml 位置。

<!-- 这个是assembly 所在位置 --><descriptor>src/main/assembly/assembly.xml</descriptor>

创建assembly.xml 文件后添加如下内容：

<assembly> <formats> <!--支持 zip，tar，tar.gz，tar.bz2，jar，dir，war 等 --> <format>tar.gz</format> <format>zip</format> <format>dir</format> </formats> <includeBaseDirectory>false</includeBaseDirectory> <fileSets> <fileSet> <directory>src/main/resources</directory> <outputDirectory>conf</outputDirectory> <fileMode>0644</fileMode> </fileSet> <fileSet> <directory>${profile.dir}</directory> <outputDirectory>conf</outputDirectory> <!-- 表示的是包含下面格式的资源文件 --> <includes> <include>*.xml</include> <include>*.properties</include> <include>**/*.xml</include> <include>**/*.properties</include> </includes> <fileMode>0644</fileMode> </fileSet> <fileSet> <directory>src/main/assembly/bin</directory> <outputDirectory>bin</outputDirectory> <fileMode>0755</fileMode> </fileSet> </fileSets> <dependencySets> <dependencySet> <outputDirectory>lib</outputDirectory> </dependencySet> </dependencySets></assembly>

fileMode 官方解释：

Similar to a UNIX permission, sets the file mode of the files included. THIS IS AN OCTAL VALUE. Format: (User)(Group)(Other) where each component is a sum of Read = 4, Write = 2, and Execute = 1. For example, the value 0644 translates to User read-write, Group and Other

上述的三个fileSet 分别是将resource 下的资源打包到config 目录下， 将assembly下的bin 启动相关脚本打包到bin 目录下， 将maven项目依赖的所有jar 包， 打包到lib 中。

具体结构如下图所示：

参考地址：
http://maven.apache.org/plugins/maven-assembly-plugin/assembly.html

zip.xml 文件配置如下

<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>release</id> <formats> <format>zip</format> </formats> <fileSets> <fileSet> <directory>${project.basedir}\src\main\config</directory> <!-- 过滤 --> <excludes> <exclude>*.xml</exclude> </excludes> <outputDirectory>\</outputDirectory> </fileSet> </fileSets> <dependencySets> <dependencySet> <useProjectArtifact>true</useProjectArtifact> <outputDirectory>lib</outputDirectory><!-- 将scope为runtime的依赖包打包到lib目录下。 --> <scope>runtime</scope> </dependencySet> </dependencySets> </assembly>

例：

<assembly> <id>assembly</id> <formats> <format>tar.gz</format> </formats> <includeBaseDirectory>true</includeBaseDirectory> <fileSets> <fileSet> <directory>${project.build.directory}/resources</directory> <outputDirectory>resources</outputDirectory> <fileMode>0755</fileMode> </fileSet> <fileSet> <directory>${project.build.directory}/config</directory> <outputDirectory>config</outputDirectory> <fileMode>0644</fileMode> </fileSet> <fileSet> <directory>${project.build.directory}/bin</directory> <outputDirectory>bin</outputDirectory> <fileMode>0755</fileMode> </fileSet> </fileSets> <dependencySets> <dependencySet> <outputDirectory>lib</outputDirectory> </dependencySet> </dependencySets></assembly>
