@thaJeztah looks like this needs another change around buildkit/util/tracing/detect/detect.go Line 159 in bbb6aac |

oh! indeed; yeah, master diverged somewhat, but I missed that that part was added. Let me fix |
This is a workaround for the brittleness when constructing OTel `Resource` objects. Internally, the OTel libraries do their own detection which can be merged with one created in code. However, the `semconv` spec versions must match. (NOT module version! the `semconv` package has multiple subpackages for each spec version, e.g. `semconv/v1.17`, `semconv/v1.21`, etc.) This creates a problem when BuildKit is used as a library - the importing app might be using a different, otherwise compatible version of the OTel libraries, so when it creates a resource, it will be merged with one of a different version. By allowing the `Resource` to be set (like the `Recorder`), the calling code can construct a resource using known consistent library versions that work, and then allow BuildKit to take over the rest of the initialization process for OTel.
