maven-assembly-plugin插件实现自定义打包

╰半夏微凉° 2023-07-03 02:52 59阅读 0赞

maven有三种插件可以用来打包：

*  maven-jar-plugin，默认的打包插件，用来打普通的project JAR包；
 *  maven-shade-plugin，用来打可执行JAR包，也就是所谓的fat JAR包；
 *  maven-assembly-plugin，支持自定义的打包结构，也可以定制依赖项等

现有maven的普通java项目，项目根路径下有files文件夹，该文件夹下有一些文件

## 1、利用resource插件将files文件夹编译到target/classes目录下 ##

<build>
      <resources>
        <resource>
          <directory>files</directory>
      	  <targetPath>/files</targetPath>
      	</resource>
      </resources>
    </build>

## 2、利用maven-assembly-plugin插件将files文件夹以及项目依赖包一起打包 ##

<build>
      <plugins>
        <plugin>
    	  <groupId>org.apache.maven.plugins</groupId>
    	  <artifactId>maven-compiler-plugin</artifactId>
    	  <configuration>
    	    <source>1.8</source>
    	    <target>1.8</target>
    	  </configuration>
    	</plugin>
        	
        <plugin>
          <artifactId>maven-assembly-plugin</artifactId>
          <configuration>
          <archive>
            <manifest>
        		<mainClass>com.asiainfo.group.kafka_ui_client.ui.KafkaClientUI</mainClass>
            </manifest>
          </archive>
          
          <descriptors>
            <descriptor>assembly.xml</descriptor>
          </descriptors>
          
          <appendAssemblyId>false</appendAssemblyId>
          </configuration>
            <executions>
        	  <execution>
        	    <id>make-assembly</id>
        		<phase>package</phase>
        	    <goals>
        		  <goal>single</goal>
        		</goals>
        	  </execution>
        	</executions>    	
        </plugin>
      </plugins>
    </build>

## 3、assembly.xml ##

<?xml version='1.0' encoding='UTF-8'?>  
    <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>make-assembly</id>  
        <formats>  
            <format>jar</format>  
        </formats>  
        <includeBaseDirectory>false</includeBaseDirectory>  
        <fileSets>  
            <fileSet>  
                <directory>${project.build.directory}/classes</directory>  
                <outputDirectory>/</outputDirectory>  
            </fileSet>  
            
        </fileSets>  
        
        
        <dependencySets>
            
            
            <dependencySet>
                <outputDirectory>/</outputDirectory>
                <useProjectArtifact>true</useProjectArtifact>
                <unpack>true</unpack>
                <scope>runtime</scope>
            </dependencySet>
            <dependencySet>
                <outputDirectory>/</outputDirectory>
                <useProjectArtifact>true</useProjectArtifact>
                <unpack>true</unpack>
                <scope>system</scope>
            </dependencySet>
        </dependencySets>
        
    </assembly>

## 4、java如何读取jar包内部文件 ##

//这个路径是jar包内的绝对路径，也是以target/classes作为根目录的绝对路径
    InputStream in = ConsumerConfig.class.getResourceAsStream("/files/consumer.properties");
