Solution

  • I think you can add this plugin inside you pom.xml and retry it.

    <plugin>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-maven-plugin</artifactId>
    <version>you spring boot version</version>
    <configuration>
      <mainClass>your main class</mainClass>
    </configuration>
</plugin>
