同时打成jar和tar包

可以使用Maven插件来同时打成jar和tar包。在pom.xml文件中添加以下配置：

<build>
  <plugins>
    <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-jar-plugin</artifactId>
      <version>3.1.2</version>
      <executions>
        <execution>
          <phase>package</phase>
          <goals>
            <goal>jar</goal>
          </goals>
        </execution>
      </executions>
    </plugin>
    <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-assembly-plugin</artifactId>
      <version>3.2.0</version>
      <executions>
        <execution>
          <phase>package</phase>
          <goals>
            <goal>single</goal>
          </goals>
          <configuration>
            <finalName>${project.artifactId}-${project.version}</finalName>
            <appendAssemblyId>false</appendAssemblyId>
            <archive>
              <manifest>
                <mainClass>com.example.Main</mainClass>
              </manifest>
            </archive>
            <descriptors>
              <descriptor>src/main/assembly/assembly.xml</descriptor>
            </descriptors>
          </configuration>
        </execution>
      </executions>
    </plugin>
  </plugins>
</build>

其中，maven-jar-plugin插件用于打jar包，maven-assembly-plugin插件用于打tar包。在src/main/assembly目录下创建assembly.xml文件，配置打tar包的规则：

<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>tar</id>
  <formats>
    <format>tar</format>
  </formats>
  <fileSets>
    <fileSet>
      <directory>${project.build.directory}</directory>
      <outputDirectory>/</outputDirectory>
      <includes>
        <include>${project.artifactId}-${project.version}.jar</include>
      </includes>
    </fileSet>
  </fileSets>
</assembly>

最后，使用以下命令进行打包：

mvn clean package

即可同时打成jar和tar包。
