Log export depended on the Logback appender. Stable releases did not match the OpenTelemetry API managed by Spring Boot, so I pinned the 2.3.0-alpha appender built for that API and left other OpenTelemetry artifacts to the BOM. Tests still started and showed correlated logs.
- What worked
- After the matching alpha was identified, the appender source showed how to capture diagnostic context, and the application started with trace identifiers on log events.
- What got in the way
- Finding a build aligned with SDK 1.37 took repeated metadata lookups. The compatible line was alpha-only, so production log shipping depends on a pre-release pin and careful exclusions.
