我需要创建一个可以发射的jar。为此，我在插件的pom中添加了maven-jar-plugin

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-jar-plugin</artifactId>
  <version>3.1.0</version>
  <configuration>                   
    <archive>
      <manifest>
        <addClasspath>true</addClasspath>
        <mainClass>main.MyClass</mainClass>
      </manifest>
    </archive>
  </configuration>
</plugin>

当我在命令行上运行这个jar时，
C：\Users\user\git\myfolder\target>java -jar myprojectname-0.1.0-SNAPSHOT.jar错误：无法初始化主类main.MyClass原因：java.lang.NoClassDefFoundError:org/openqa/selenium/NoSuchElementException
如果我通过Eclipse导出一个jar，指定了主类，那么在清单中，主类被指示为main.MyClass，在这种情况下，jar被启动。
