Stepping into instrumentation in IntelliJ

[jtayl222]

When using IntelliJ to debug my application that is instrumented with OpenTelemetry (-javaagent:opentelemetry-javaagent.jar -Dotel.javaagent.configuration-file=agent.properties) I'd like to be able to step into and through OpenTelemetry source. While I can see the call stack, the corresponding java source file is not displayed.

Here is an example of the top several stack frames:

get:64, LazyStorage (io.opentelemetry.javaagent.shaded.io.opentelemetry.context)
get:72, ContextStorage (io.opentelemetry.javaagent.shaded.io.opentelemetry.context)
root:104, Context (io.opentelemetry.javaagent.shaded.io.opentelemetry.context)
current:92, Context (io.opentelemetry.javaagent.shaded.io.opentelemetry.context)
currentContext:23, Java8BytecodeBridge (io.opentelemetry.javaagent.bootstrap)

What can I do to get IntelliJ to show the OpenTelemetry source file in an IntelliJ editor pane while debugging?

Thanks for the recommendation. We haven't successfully been able to build https://github.com/open-telemetry/opentelemetry-java without the shadow entries, yet. We will get back to you when we can provide more feedback.

@jtayl222 @laurit Do I need a collector to debug Instrumentation?

[laurit]

no, you don't
