I am developing a code from https://www.dineshonjava.com/microservices-with-spring-boot/. When I update the spring-boot-starter-parent from 1.5.4.RELEASE to 2.0.4.RELEASE, build got failed.
Could anyone please guide me what is the issue ?
Project build error: 'dependencies.dependency.version' for org.springframework.cloud:spring-cloud-starter-eureka-server:jar is missing.
Another error:
Multiple annotations found at this line:

As indicated in my comment, some starters were renamed: https://github.com/spring-projects/spring-cloud/wiki/Spring-Cloud-Edgware-Release-Notes
A number of starters did not follow normal Spring Cloud naming conventions. In Edgware, use of the deprecated starter will log a warning with the name of the new starter to use in its place.
So change:
spring-cloud-starter-eureka-server
to spring-cloud-starter-netflix-eureka-server.
Add the following in to your pom.xml
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
<java.version>1.8</java.version>
<spring-cloud.version>Hoxton.RC1</spring-cloud.version>
</properties>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
</dependency>
OR
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
</dependency>
<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-dependencies</artifactId>
<version>${spring-cloud.version}</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>
<repositories>
<repository>
<id>spring-milestones</id>
<name>Spring Milestones</name>
<url>https://repo.spring.io/milestone</url>

Add the following int the Pom.xml
<properties>
<java.version>1.8</java.version>
<spring-cloud.version>Greenwich.RELEASE</spring-cloud.version>
</properties>
<dependencies>
<dependency>

Even I got the similar error when I was adding dependency for hystrix.
Error : Project build error: 'dependencies.dependency.version' for
org.springframework.cloud:spring-cloud-starter-hystrix:jar is missing
It worked after changing netflix <artifactId>
from: spring-cloud-starter-hystrix
to: spring-cloud-starter-netflix-hystrix
I also was facing similar problem. Using the below pom.xml helped
<properties>
<java.version>1.8</java.version>
<spring-cloud.version>Hoxton.SR3</spring-cloud.version>
</properties>
<dependencies>
<dependency>

1º) remove dependency from your pom.xml and save the file;
2º) Go to the STS project > right click > Spring > Edit Starters > search to Eureka Discovery Client and mark checkbok > OK.
This action solved my problem.
There are a couple of things here.
I was trying to create the Eureka server and I faced a couple of problems.
First things
If you are using spring-cloud-starter-eureka-server then change it to spring-cloud-starter-netflix-eureka-server.
The link will give the details of the changes.
https://github.com/spring-projects/spring-cloud/wiki/Spring-Cloud-Edgware-Release-Notes
I recently created the starter project from https://start.spring.io/ and it has the latest changes in pom.xml
This is how it looks like
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
</dependency>
You need to make sure that the eureka server dependency version is correct.
You can make sure by adding <spring-cloud.version>Greenwich.RELEASE</spring-cloud.version> in properties tag and ${spring-cloud.version} in dependencyManagement's version tag
If you do not see the <dependencyManagement> tag then add the whole dependency in your pom.xml
<properties>
<java.version>1.8</java.version>
<spring-cloud.version>Greenwich.RELEASE</spring-cloud.version>
</properties>
<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-dependencies</artifactId>
<version>${spring-cloud.version}</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>
I hope it helps.
