quarkus: JDBC driver not detected while building Quarkus with Gradle

Hi Quarkus team!

I am in the middle of migrating a Thorntail project to Quarkus and it looks like I’m blocked by a bug that was supposed to be fixed here: https://github.com/quarkusio/quarkus/issues/1645

Here is a reproduction repository: https://github.com/gwenneg/quarkus-quickstarts/tree/master/hibernate-orm-resteasy

Run the ./gradlew clean build --stacktrace command to get the following error:

org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':quarkusBuild'.
