I checked this out locally, ran ./gradlew :sdk:trace:publishToMavenLocal, inspected the opentelemetry-sdk-trace jar and still see JC tool resources in META-INF.

Not really unexpected. Like in instrumentation repo for shading we first build a jar with shaded dependencies, then we extract it and in the module where we wish to include the shaded dependency we copy the directory that we extracted in the previous step. The consequence of that is that you may need to clean both the final target module and the module that does the shading to get the files removed.

Ok so for this PR to be useful, would someone (you or I) need to go the extra step and clean the final target module?

This is what I see locally when I check out the PR:

./gradlew clean :sdk:trace:publishToMavenLocal
jar tf ~/.m2/repository/io/opentelemetry/opentelemetry-sdk-trace/1.60.0-SNAPSHOT/opentelemetry-sdk-trace-1.60.0-SNAPSHOT.jar | grep META-INF

😮

Something's up @trask. I just reran your exact command on my local copy of the branch, after being sure to delete the 1.60.0-SNAPSHOT directory:

opentelemetry-java git:(jctools-maven) jar tf ~/.m2/repository/io/opentelemetry/opentelemetry-sdk-trace/1.60.0-SNAPSHOT/opentelemetry-sdk-trace-1.60.0-SNAPSHOT.jar | grep META-INF

So far I have treated this as a local build issue. You could try ./gradlew clean :sdk:trace:publishToMavenLocal --no-build-cache and see if that changes anything. Look at sdk/trace-shaded-deps/build/extracted/shadow/META-INF if all goes well you shouldn't see maven there. If it is not there but is in the final jar then probably the final jar wasn't rebuilt and came form build cache.
