Configuring OpenTelemetry Project Attribute in Java Spring Boot

Hi, I’m integrating OpenTelemetry with Phoenix in my Java Spring Boot app using the OpenTelemetry Java SDK (OTLP HTTP exporter). I added a project attribute in the resource configuration like this:

Resource resource = Resource.getDefault()
  .merge(Resource.create(Attributes.of(
    AttributeKey.stringKey("service.name"), "demoapp",
    AttributeKey.stringKey("project"), "my-project"
  )));

However, traces are still going to the default project. Could you confirm the correct way to configure the project attribute so that traces route properly? Thanks!
