When I add this to my project parent pom:
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
<version>2.1.3.RELEASE</version>
</dependency>
the project run fails like this:

When I remove the dependency, the project runs successfully.
I'm just trying to add a Eureka client to register center but it doesn't work. When I create a new project with Spring Initializr though, it works well.
Every answer helps.

Generally, Eureka client application is rest service which exposes REST services. Which will be accessible from direct UI or another Spring boot services. We can also register multiple instances of the same service to the server. In case of multiple instances of the same server requires load balancing.
If Eureka server configuration is not configured then here is an article for Eureka server configuration. Generally, Eureka client application is rest service which exposes REST services. Which will be accessible from direct UI or another Spring boot services.
The @EnableEurekaServer annotation is used to make your Spring Boot application acts as a Eureka Server. The code for main Spring Boot application class file is as shown below − Make sure Spring cloud Eureka server dependency is added in your build configuration file.
Eureka Server is an application that holds the information about all client-service applications. Every Micro service will register into the Eureka server and Eureka server knows all the client applications running on each port and IP address. Eureka Server is also known as Discovery Server.
This is a common Spring Boot <-> Spring Cloud version compatibility mismatch problem. Have a look at the Table 1. Release train Spring Boot compatibility
section at spring.io/projects/spring-cloud:
Spring Cloud <-> Spring Boot
2020.0.x (aka Ilford) <-> 2.4.x
Hoxton <-> 2.2.x, 2.3.x (Starting with SR5)
Greenwich <-> 2.1.x
Finchley <-> 2.0.x
Also see the complete list of all the spring-cloud-dependencies
versions at Maven Central.
So in your case using Spring Boot 2.1.7.RELEASE
, make sure to also use a Greenwich.SRx
release (this is why Said Dekkaki`s answer works):
<properties>
<spring-cloud.version>Greenwich.SR6</spring-cloud.version>
</properties>
Or better: upgrade to a newer Spring Boot version (as Neeush Sreenivas suggested):
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.2.2.RELEASE</version>
</parent>
Or even better: Use both the most current versions - as of writing: spring-boot-starter-parent
with 2.4.1
and spring-cloud-dependencies
with 2020.0.0
.
