I don't know how, but at some point the test folders have been included in Properties -> Deployment Assembly.
After I've removed them everything was solved.
I'm not sure why they were there in the first place though I'm pretty sure I haven't added them manually.
Thanks for the great tool.
Do they by any chance come back if you do Maven > Update Project Configuration in the Context menu of the project ?
if yes then you know where it is from and sounds like a bug or misconfiguration somewhere...
It doesn't come back when I update the maven configuration.
When I've tried to update the configuration before the change at the Deployment Assembly the test folder was still there.
I guess it's been included while I was trying to figure out the right configuration to use in the project and it's never been deleted. I'm sure I've never added it manually.
By the way, thanks for the reply.
