maven 使用assembly 进行打包的方法_Java教程

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。

1 2	`<!-- 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：

maven 使用assembly 进行打包的方法

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>
