[Szymon Tarnowski]

Remove dependency for JCenter/Bintray.

Tests case:
Create Github action that deploys project to nexus3 repository:

• use docker image for nexus3 repository.
• before tests, create tests user with login and password
• check if the project was deploy
• try to add requirements same a maven central required (besides checking if the certificate is publicly available )
