Prometheus exporter: struggle to compile


I’m trying to compile the Prometheus exporter (GitHub - dremio-hub/dremio-prometheus-exporter)

I get the following error:

I think I’m failing to update the pom.xml correctly (I have 0 experience in Java)
what version should I put ? and where ?

Is there another Prometheus exporter ?

Thank you
