Unable to find a JDBC driver corresponding to the database kind 'postgresql' for the default

While connecting to postgres db from quarkus application but following error is thrown while building

Check if it's a typo, otherwise provide a suitable JDBC driver extension, define the driver manually, or disable the JDBC datasource by adding 'quarkus.datasource.jdbc=false' to your configuration if you don't need it.

I am following the official tutorial https://quarkus.io/guides/datasource And it seems everyting is right? could someone help to find why this issue is occuring.

As far as I can tell from the description, you are missing the quarkus-jdbc-postgresql dependency.

Also note that if you add it, you don't need to add the agroal or org.postgresql:postgresql dependencies
