ERROR: java.lang.NoClassDefFoundError: co/elastic/apm/api/ElasticApm

Hi, the problem is the scope you use for the dependency:

@miguel.longo

<dependency>
  <groupId>co.elastic.apm</groupId>
  <artifactId>apm-agent-api</artifactId>
  <version>1.43.0</version>
  <scope>compile</scope>
</dependency>

You should remove the <scope>compile</scope> from the declaration, because the dependency needs to be on your runtime classpath. That should solve the issue.
