Build error on TravisCI without logs

I am creating a project to use TravisCI, however when I click on github and run it, it doesn't work and there are no logs. I'm looking for a way to debug what's the problem, but it's hard (obviously) without the logs.

Here is my .travis.yml

file:

language: java
sudo: false
script: mvn clean verify

      

        
        
        
      

    

Here's the TravisCI:

When I run the command mvn clean verify

in my project directory everything works and the build succeeds.

I am wondering if there is some way that I can dig deeper into what is going wrong, or if I am missing something obvious.
