mvn build fails when following getting started guide

[dkranz]

I was following the guide. When I got to section 5.15 where you click the Run button in the new Che workspace I saw the following error:

scl enable rh-maven33 'mvn compile vertx:run -f -Dvertx.disableDnsResolver=true'https://routeyls1kykd-dkranz-che.9a6d.starter-us-east-1a.openshiftapps.com

Thanks for detailed report @dkranz! This seems to be a duplicate of #2152 - in such a case could you subscribe to that issue and close this one?

[rhopp]

@bartoszmajsak, @dkranz To me it seems more like duplicate of #2856 (the macro ${current.project.path} sometimes returns empty string - and because of that the build fails... the option -f expects an argument)
This was also reported upstream (eclipse-che/che#9321), but unfortunately it was closed, even though I provided steps to reproduce on latest upstream. I'll try to get in contact with che-qe guys to reopen it.

[bartoszmajsak]

@rhopp Well, then we have two cases where -f is causing trouble. For Vertx and it's what you described, for WF Swarm/Thorntail it's https://issues.jboss.org/browse/THORN-2049

Would be good to understand what is this "sometimes" you mention :)

@bartoszmajsak One of the use-cases where it's 100% reproducible is described in this comment: eclipse-che/che#9321 (comment) and the screencast of that is in the comment below that ;-)
