maven 打包以某个类为启动类

<build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-jar-plugin</artifactId>
                <configuration>
                    <archive>
                        <manifest>
                            <mainClass>com.example.demo.TestKey</mainClass>
                          <addClasspath>true</addClasspath>
                        </manifest>
                    </archive>
                </configuration>
            </plugin>
        </plugins>
    </build>

定义一个 java 启动类

package com.example.demo;
public class TestKey {
    public static void main(String[] args) {
        System.out.println("启动了.............");
    }
}

<build>
  <finalName>${project.artifactId}</finalName>
  <plugins>
    <plugin>
      <artifactId>maven-assembly-plugin</artifactId>
      <configuration>
        <!--这部分可有可无,加上的话则直接生成可运行jar包-->
        <archive>
          <manifest>
            <mainClass>com.slf.oled.Demo</mainClass>
          </manifest>
        </archive>
        <descriptorRefs>
          <descriptorRef>jar-with-dependencies</descriptorRef>
        </descriptorRefs>
      </configuration>
    </plugin>
  </plugins>
    </build>
