本文介绍两种使用Maven进行项目打包的方法。方法一通过maven-assembly-plugin插件配置，包括设置main-class、依赖项合并等；方法二采用maven-jar-plugin插件，并同样详细配置了main-class及依赖项。

方法一:Fat jar

<build>
		<plugins>
			<plugin>
				<groupId>org.apache.maven.plugins</groupId>

					<appendAssemblyId>false</appendAssemblyId>
					<descriptorRefs>  
            		<descriptorRef>jar-with-dependencies</descriptorRef>  
       				 </descriptorRefs>  
        				<archive>  
         		   			<manifest>  
          				      <mainClass>com.pxene.dmp.main.CrawlerManager</mainClass>  
         				   </manifest>  
      				  </archive>

						<goals>
							<goal>single</goal>
						</goals>
					</execution>
				</executions>
			</plugin>

		</plugins>
	</build>

方法二：fat jar

 <build>
    <plugins>
        <plugin>
            <artifactId>maven-assembly-plugin</artifactId>
            <configuration>
                <archive>
                    <manifest>
                        <!--这里指定要运行的main类-->
                        <mainClass>com.wenge.QueryTest</mainClass>
                    </manifest>
                </archive>
                <descriptorRefs>
                    <descriptorRef>jar-with-dependencies</descriptorRef>
                </descriptorRefs>
            </configuration>
            <executions>
                <execution>
                    <id>make-assembly</id> <!-- 此处指定继承合并 -->
                    <phase>package</phase> <!-- 绑定到打包阶段 -->
                    <goals>
                        <goal>single</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <configuration>
                <source>8</source>
                <target>8</target>
            </configuration>
        </plugin>
    </plugins>
    </build>

方法三：核心包

<build>
		<plugins>
			<plugin>
				<groupId>org.apache.maven.plugins</groupId>
				<artifactId>maven-compiler-plugin</artifactId>
				<version>3.3</version>
				<configuration>
					<source>1.7</source>
					<target>1.7</target>
				</configuration>
			</plugin>
			<plugin>
				<groupId>org.apache.maven.plugins</groupId>
				<artifactId>maven-assembly-plugin</artifactId>
				<version>2.5.3</version>
				<configuration>
					<descriptors>
						<descriptor>src/main/resources/assembly.xml</descriptor>
					</descriptors>
					<appendAssemblyId>false</appendAssemblyId>
				</configuration>
				<executions>
					<execution>
						<id>assembly</id>
						<phase>package</phase>
						<goals>
							<goal>single</goal>
						</goals>
					</execution>
				</executions>
			</plugin>
			<plugin>
				<groupId>org.apache.maven.plugins</groupId>
				<artifactId>maven-jar-plugin</artifactId>
				<version>2.4</version>
				<configuration>
					<archive>
						<manifest>
							<addClasspath>true</addClasspath>
							<classpathPrefix>lib/</classpathPrefix>
							<mainClass>com.pxene.dmp.main.CrawlerManager</mainClass>
						</manifest>
					</archive>
				</configuration>
			</plugin>
		</plugins>
	</build>

assembly.xml配置

<?xml version="1.0" encoding="UTF-8"?>
<assembly xmlns="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.3"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.3 
          					  http://maven.apache.org/xsd/assembly-1.1.3.xsd">
	<id>outer-lib</id>
	<formats>
		<format>dir</format>
	</formats>
	<includeBaseDirectory>false</includeBaseDirectory>
	<dependencySets>	
		<dependencySet>
			<outputDirectory>lib</outputDirectory>
		</dependencySet>
	</dependencySets>
</assembly>

方法四：fat jar

 <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
<!--                <version>${spring-boot.version}</version>-->
                <version>2.6.13</version>
                <configuration>
                    <mainClass>com.test.kafkatest.KafkaTestApplication</mainClass>
                    <fork>true</fork> <!-- 可选，用于在新进程中运行应用 -->
                </configuration>
                <executions>
                    <execution>
                        <goals>
                            <goal>repackage</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

方法五：resource和依赖外置

        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>

                <version>2.4</version>
                <configuration>
                    <!--不打包资源文件-->
                    <excludes>
                        <exclude>*.yml</exclude>
                        <exclude>*.properties</exclude>
                    </excludes>
                    <archive>
                        <manifest>
                            <addClasspath>true</addClasspath>
                            <!--MANIFEST.MF 中 Class-Path 加入前缀-->
                            <classpathPrefix>lib/</classpathPrefix>
                            <!--jar包不包含唯一版本标识-->

                        <manifestEntries>
                            <!--MANIFEST.MF 中 Class-Path 加入资源文件目录-->
                            <Class-Path>./resources/</Class-Path>
                        </manifestEntries>
