    That makes no sense to me, (mainly since it was working on my computer but not on the VM) but it seems that the problem was that  I am using the google sheet API on the same project, which is using the jackson library as well. So it seemed that there was some problem with the maven dependencies there. I directly imported both the dropbox and the google maven on the same project, and maven automatically managed to handle the dependencies. Initially i was importing it as a jar file, causing the problem.

     

    Thanks for the hints

It's difficult to say off hand what the problem may be, but as it's only happening in one environment for you, and not the other, it sounds like it may be specific to the setup of that VM. Can you check that the Jackson library is installed properly there, and that you only have one version installed? You may also want to try upgrading it.

      Can I get a look at your pom.xml so that I can understand how you managed to make both work. Because I'm getting the same issue.

      The JacksonFactory dependency's version for both the APIs is different which is causing the issue in my case.

      Thanks!
