Spring Cloud Netflix EurekaEndpoint ClassNotFound

JDK 17 Spring Boot: 2.6.4 Spring Cloud: 2021.0.1

Eureka server is up and running and I can see the Eureka Dashboard on localhost:8000 which is configured in my application.yml

But, when configuring the client, the application doesn't start at all, with below stack trace:

Exception in thread "main" java.lang.IllegalArgumentException: Cannot instantiate interface org.springframework.boot.BootstrapRegistryInitializer : org.springframework.cloud.netflix.eureka.config.EurekaConfigServerBootstrapper

Process finished with exit code 1

However, the application was up and running in Spring boot version 2.0.5. Just started the upgrade process for better performance.

Here's my client main method code:

@SpringBootApplication
@EnableEurekaClient
@ComponentScan(basePackages = {"com.cryptified.exchange.coin.bitcoin", "com.cryptified.core.app"})
@EnableFeignClients(basePackages = {"com.cryptified.core.app.gateway.coinGateway", "com.cryptified.exchange.coin.bitcoin"})
@EnableAsync
public class BitcoinApplication {

    public static void main(String[] args) {
        SpringApplication.run(BitcoinApplication.class, args);
    }
}

Here's client application.yml config:

eureka:
  client:
    serviceUrl:
      defaultZone: ${EUREKA_URI:http://localhost:8000/eureka}
  instance:
    preferIpAddress: true

hystrix:

Please close this. the issue was in the pom.xml. had to use spring-cloud-starter-netflix-eureka-client.
