The answer can be found here-https://chowdera.com/2021/12/202112211422209581.html

The dependency is incorrect needs to be changed

from spring-cloud-netflix-eureka-server

to spring-cloud-starter-netflix-eureka-server

Solution 2:^[2]

The error itself says that you have two beans with the same name. Try renaming one of those. Or use the property it suggests in application.properties file. Even if it's not working then give me the snapshot of Discovery Client and Server Classes.

Solution 3:^[3]

<dependency>
                  <groupId>org.springframework.cloud</groupId>
                  <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
                  <version>3.1.1</version>
            </dependency>
