前言:本文将告诉你如何将程序Jar与与依赖Jar及配置文件分离打包,以下列举了两种不同Maven打包方式,其打包效果一致!
一、第一种Maven打包方式,将jar及resources下全部配置文件,拷贝到指定目录:
<!--配置项-->
<properties>
<!--自定义配置-->
<project.jar.output.directory>E:/IDEAFile/filecopy/target/roject</project.jar.output.directory>
</properties>
<build>
<plugins>
<!--项目依赖的jar文件,放置默认配置目录下-->
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
<!-- 设置jar的入口类 -->
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>2.6</version>
<configuration>
<archive>
<manifest>
<addClasspath>true</addClasspath>
<classpathPrefix>lib/</classpathPrefix>
<mainClass>com.example.filecopy.FileCopyApplication</mainClass>
</manifest>
</archive>
</configuration>
</plugin>
<!-- 使用maven-resources-plugin插件复制resources目录下所有文件到指定的路径-->
<plugin>
<artifactId>maven-resources-plugin</artifactId>
<executions>
<execution>
<id>copy-resources</id>
<phase>validate</phase>
<goals>
<goal>copy-resources</goal>
</goals>
<configuration>
<outputDirectory>${project.build.directory}/project</outputDirectory>
<resources>
<resource>
<directory>src/main/resources</directory>
<filtering>true</filtering>
</resource>
</resources>
</configuration>
</execution>
</executions>
</plugin>
<!--使用maven-antrun-plugin插件将jar复制到指定的目录下-->
<plugin>
<artifactId>maven-antrun-plugin</artifactId>
<executions>
<execution>
<!-- 在maven进行package的时候执行-->
<phase>package</phase>
<configuration>
<tasks>
<!--todir:是将要复制jar包到的地方,overwrite:是否重写-->
<copy todir="${project.jar.output.directory}" overwrite="true">
<!--获取父目录下的target文件夹中的jar-->
<fileset dir="${project.build.directory}">
<include name="*.jar"/>
</fileset>
</copy>
</tasks>
</configuration>
<goals>
<goal>run</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
第二种Maven打包方式使用 assembly插件,将jar及配置文件进行压缩打包到指定目录:
<plugins>
<!-- 项目依赖的jar文件,放置默认配置目录下-->
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
<!-- 设置jar的入口类-->
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>2.6</version>
<configuration>
<archive>
<manifest>
<addClasspath>true</addClasspath>
<classpathPrefix>lib/</classpathPrefix>
<mainClass>com.example.filecopy.FileCopyApplication</mainClass>
</manifest>
</archive>
</configuration>
</plugin>
<!--assembly插件-->
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-assembly-plugin</artifactId>
<version>2.4</version>
<configuration>
<!--指定压缩包名称-->
<finalName>project</finalName>
<!--指定assembly配置文件配置-->
<descriptors>
<descriptor>/assembly/assembly.xml</descriptor>
</descriptors>
<!--打包tar.gz输出target文件夹中-->
<outputDirectory>${project.build.directory}</outputDirectory>
<appendAssemblyId>false</appendAssemblyId>
</configuration>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>single</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
assembly文件:
<assembly xmlns="http://maven.apache.org/ASSEMBLY/2.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/ASSEMBLY/2.0.0 http://maven.apache.org/xsd/assembly-2.0.0.xsd">
<id>leaves</id>
<formats>
<!--压缩文件形式 可选 zip tar.gz等 -->
<format>zip</format>
</formats>
<includeBaseDirectory>true</includeBaseDirectory>
<!-- 项目文件处理 -->
<fileSets>
<!--配置文件输出位置根目录文件夹下-->
<fileSet>
<directory>${basedir}/src/main/resources</directory>
<includes>
<include>**</include>
</includes>
<filtered>true</filtered>
<outputDirectory>${file.separator}</outputDirectory>
</fileSet>
<!-- 项目代码生成的jar文件放在根目录 -->
<fileSet>
<directory>${project.build.directory}</directory>
<outputDirectory>${file.separator}</outputDirectory>
<includes>
<include>*.jar</include>
</includes>
</fileSet>
</fileSets>
</assembly>
