Major When configuring the camel-zipkin components via Spring DSL as indicated in the documented example:
<!-- configure how to reporter spans to a Zipkin collector
(the dependency is io.zipkin.reporter2:zipkin-reporter-spring-beans) -->
<bean id="http" class="zipkin2.reporter.beans.AsyncReporterFactoryBean">
<property name="sender">
<bean id="sender" class="zipkin2.reporter.beans.OkHttpSenderFactoryBean">
<property name="endpoint" value="http://localhost:9411/api/v2/spans"/>
</bean>
</property>
<!-- wait up to half a second for any in-flight spans on close -->
<property name="closeTimeout" value="500"/>
</bean>
<!-- setup zipkin tracer -->
<bean id="zipkinTracer" class="org.apache.camel.zipkin.ZipkinTracer">
<property name="serviceName" value="dude"/>
<property name="spanReporter" ref="http"/>
</bean>
a NoSuchMethodError is encountered when trying to report the span to the configured server:

This appears to be due to the inclusion of the older io.zipkin.java/zipkin1.19.2 dependency, which does not have a method signature matching the one requested by the brave V2SpanConverter.
Exclusion of the 1.19.2 dependency and explicit inclusion of a later version (Iused 2.4.5) seems to resolve the issue and spans are correctly reported.
