resource-server fails to run with documented instructions

[pedrolamarao]

According with instructions from resource-server README, this command should start the server:

mvn spring-boot:run '-Dokta.oauth2.issuer=https://${domain}/oauth2/default'

Running this against the master branch, with Eclipse Temurin 11.0.16, I get this result:
