-Importing the `opentelemetry-bom` and `opentelemetry-instrumentation-bom` BOMs

+To ensure version alignment across all OpenTelemetry dependencies, you must

-If you import the `spring-boot-dependencies` BOM, you have to declare it after

+When using Maven, import the OpenTelemetry BOMs before any other BOMs in your

+Gradle selects the

+of a dependency when multiple BOMs, so the order of BOMs is not important.
