Latest exporter-auto incompatible with latest opentelemetry agent

[joao-melo-ingka]

The following combination:

io.opentelemetry.javaagent:opentelemetry-javaagent:1.30.0 (latest, as of now)
com.google.cloud.opentelemetry:exporter-auto:0.25.2-alpha:shaded (latest, as of now)

Doesn't work.

If I downgrade the opentelemetry java agent to 1.28.0, it works.

Thanks for the issue, I was able to reproduce it locally.

The root cause is mostly the recent breaking changes in the upstream OpenTelemetry Java repo(s). Need to update the dependencies used in the project and fix the breaking changes.

After #267 got merged, I manually built the auto-exporter from the main branch to make sure it is compatible with the latest OTel agent.

The next release should work with latest OTel agent.
