The root cause of this is following snippet in the pom.xml (as I finally found out), which by disabling allow dummy application to start:

<!--
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-jooq</artifactId>
		</dependency>
		-->

Maybe you could add this to documentation of the starter application for new users...

This issue has been previously reported as #8793, but I checked that case and guy didn't use jooq framework in his pom.xml, so probably different issue.

[snicoll]

that starter has nothing to do with the problem. The only thing that it does is making the application fail for something else entirely (the application does not start because you're using Jooq and you haven't provided anything to configure the datasource).

The stacktrace there seems to be related to a change in #9781 and can be fixed but that's not why the application doesn't start (please review the "APPLICATION FAILED TO START" report.

[archenroot]

I understand it, I just would expect that from the generator either I use any of the options I always get working dummy app.

[snicoll]

I don't think you do. It is not reasonable to expect start.spring.io to always produce a working app. As a matter of a fact, this issue is now fixed and that app of yours will still fail (again, nothing to do with the actual problem). You can also create a dummy app with just data-jpaand see what happens.

If you have more questions, let's chat on Gitter. Thanks.

Thanks for clarification and therefore for your time. 2017-08-20 18:31 GMT+02:00 Stéphane Nicoll <notifications@github.com>:
