Zipkin with Spring Boot 2.2 and Hoxton Cloud

Question

I wanted to update my project Zipkin setup to Spring Boot 2.2.2.RELEASE and Spring Cloud Hoxton.RELEASE but it looks like simple jars update is not enough.

I thought the old setup (it was working fine for Spring Boot 2.1.5.RELEASE and Greenwich.SR2) would also work for Boot 2.2.2.RELEASE and Hoxton.RELEASE but it appears I still miss something here.

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.2.2.RELEASE</version>
        <relativePath/>
    </parent>

    <properties>
        ...
        <spring-cloud.version>Hoxton.RELEASE</spring-cloud.version>
<!--        <zipkin.version>2.12.9</zipkin.version> does not work either-->
        <zipkin.version>2.11.8</zipkin.version>
        ...  
    </properties>

            <scope>runtime</scope>
        </dependency>

    </dependencies>

I'm getting the following exception (java.lang.NoClassDefFoundError: zipkin2 /internal/Buffer$Writer):

Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'webMvcMetricsFilter' defined in class path resource [org/springframework/boot/actuate/autoconfigure/metrics/web/servlet/We

Answer 1

It's a version problem. Zipkin officially recommends use zipkin-server instate of customer server after spring-boot 2.x.

For me, the 2.12.9 library works well under spring-boot 2.1.8.RELEASE with spring-cloud Greenwich.SR6
