Re-enable codecov on travis

[diegoceccarelli]

commit: d3d6398 disabled sending the report to codecov because we had to switch from cobertura to jacoco (cobertura wasn't compatible with openjdk11).

Find a way to send the report to codecov (it can be done also change the codecoverage framework in case it is needed)

Hello @diegoceccarelli

I saw your job posting on upwork. I am happy to contribute to your open source project without any charges. Please, give me time to get back to you. :)

@mayank-budhiraja woah that was quick, I'm going to keep the upwork open because that's an exercise for me to learn how to delegate :) if you want to contribute you are welcome, I have many things to do 👍

Hi Diego,

Hope your doing good.

I also saw your post on Upwork and had a look on both the issues. Please let me know if you want to me to contribute. The only request I have for you is to allow me to some time as I am working for limited hours.

Thanks & Regards.
