最近遇到一个朋友遇到一个项目需要将maven的依赖包和配置文件分开打包然后用脚本执行程序。这样的好处在于可以随时修改配置文件内容及查看jar包。如果将所有打成一个jar包就会有个问题（例如：修改数据库连接位置）
1. 使用maven-dependency-plugin 插件将 <build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-dependency-plugin</artifactId> <executions> <execution> <id>copy-dependencies</id> <phase>package</phase> <goals> <goal>copy-dependencies</goal> </goals> <configuration> <!--${project.build.directory} class的输出目录不做设置的话默认代表项目根目录的target目录--> <outputDirectory>${project.build.directory}/lib</outputDirectory> <excludeTransitive>false</excludeTransitive> <stripVersion>false</stripVersion> <includeScope>runtime</includeScope> </configuration> </execution> </executions> </plugin> </plugins> </build> 2. 使用maven-jar-plugin插件移除配置文件将其不打包进jar包中，并可以打包后的jar包输出到指定路径 <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-jar-plugin</artifactId> <configuration> <!-- 指定打包的jar包输出路径--> <outputDirectory> ${project.build.directory}/lib </outputDirectory> <!--不打入jar包的文件类型或者路径--> <excludes> <exclude>**/*.properties</exclude> <exclude>**/*.xml</exclude> <exclude>**/*.yml</exclude> <exclude>static/**</exclude> <exclude>templates/**</exclude> </excludes> </configuration> </plugin> 3. 使用maven-resources-plugin插件将需要复制的文件复制到指定路径（例：将配置文件提取到指定路径） <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-resources-plugin</artifactId> <executions> <execution> <id>copy-resources</id> <phase>package</phase> <goals> <goal>copy-resources</goal> </goals> <configuration> <encoding>UTF-8</encoding> <!--打成jar包后复制到的路径--> <outputDirectory> ${project.build.directory}/conf </outputDirectory> <resources> <resource> <!--项目中的路径--> <directory>src/main/resources/</directory> </resource> </resources> </configuration> </execution> <!--可配置多个提取复制路径只需要 “<id>”名字不一样即可--> <execution> <id>copy-bulid</id> <phase>package</phase> <goals> <goal>copy-resources</goal> </goals> <configuration> <encoding>UTF-8</encoding> <outputDirectory> ${project.build.directory}/bin </outputDirectory> <resources> <resource> <directory>build/</directory> </resource> </resources> </configuration> </execution> </executions> </plugin> 使用maven命令执行打包命令 mvn clean package
