I am developing Microservices specifically "zipkin-service". I have taken a reference from link: https://www.baeldung.com/tracing-services-with-zipkin.

Could anyone please guide what's the issue ?

When I added below dependencies, then I get the 

<dependency>
    <groupId>io.zipkin.java</groupId>
    <artifactId>zipkin-server</artifactId>
</dependency>
<dependency>
    <groupId>io.zipkin.java</groupId>
    <artifactId>zipkin-autoconfigure-ui</artifactId>
    <scope>runtime</scope>
</dependency>

Error:

Project build error: 'dependencies.dependency.version' for io.zipkin.java:zipkin-autoconfigure-ui:jar is missing.

add this under your section at the end of your pom.xml. you may need to add for all the dependencies.

<dependency>
  <groupId>io.zipkin.java</groupId>
  <artifactId>zipkin-autoconfigure-ui</artifactId>
  <version>what-ever-version-number</version></dependency>

  • Ideally it should be fetched by Parent pom, but looks like its not happening, hence added latest versions too. @EnableZipkinServer is from import zipkin2.server.internal.EnableZipkinServer; now – Jeff Cook Aug 20 '18 at 16:11
  • correct, by looking at your pom, your parent is spring-boot-starter, so you need to add it in your pom. – Jayesh Aug 20 '18 at 16:17
