OpenTelemetry package missing in mvn build

By adding opentelemetry-semconv dependency in pom.xml the package cannot be recognized , I used external jar file from Gradle repository and it works!

<dependency>
<groupId>io.opentelemetry</groupId>
<artifactId>opentelemetry-semconv</artifactId>
<version>1.21.0-alpha</version>
<scope>compile</scope>
</dependency>

changed milestone to %Distributed Tracing For R-Pulsar #

added Non-blocking issue label

assigned to @sikaddou

after changing the scope from runtime to compile the maven build finished with no bugs however in the execution a lot of bugs appears
