I am experimenting with adding open-telemetry to my Java projects.

I have a project where I have an API based on swagger-ui as a jersey-based servlet.

I normally run this using the jetty-maven plugin as a war:

 <plugin> <groupId>org.eclipse.jetty</groupId> <artifactId>jetty-maven-plugin</artifactId> <version>${jetty-maven-plugin.version}</version> <configuration> <webApp> <war>${project.build.directory}/main-api.war</war> </webApp> <scan>1</scan> <contextHandlers> <contextHandler implementation="org.eclipse.jetty.server.handler.ContextHandler"> <contextPath>/swagger-ui</contextPath> <resourceBase>${project.build.directory}/${project.build.finalName}/swagger-ui </resourceBase> <handler implementation="org.eclipse.jetty.server.handler.ResourceHandler"/> </contextHandler> </contextHandlers> </configuration> </plugin>

How can I add the opentelemetry-java-instrumentation as java-agent to this proces?

Try something like this:

<project> ... <properties> <opentelemetry.version>1.24.0</opentelemetry.version> </properties> <build> <plugins> <plugin> <artifactId>maven-dependency-plugin</artifactId> <version>3.5.0</version> <executions> <execution> <id>download-opentelemetry-javaagent</id> <phase>process-resources</phase> <goals> <goal>copy</goal> </goals> <configuration> <artifactItems> <artifactItem> <groupId>io.opentelemetry.javaagent</groupId> <artifactId>opentelemetry-javaagent</artifactId> <version>${opentelemetry.version}</version> <destFileName>opentelemetry-javaagent.jar</destFileName> </artifactItem> </artifactItems> </configuration> </execution> </executions> </plugin> <plugin> <groupId>org.eclipse.jetty</groupId> <artifactId>jetty-maven-plugin</artifactId> ... <configuration> ... <jvmArgs> <jvmArg>-javaagent:${project.build.directory}/opentelemetry-javaagent.jar</jvmArg> </jvmArgs> </configuration> </plugin> </plugins> </build>
</project>
