Are there any chanche to get this great plugin works on Redmine 4.1.1?

Probably not. This project isn't being supported any longer.

[guitooliveira]

Yes, i create a fork with modified codes to run in redmine 4.1.1 as well: https://github.com/guitooliveira/redmine-contracts-with-time-tracking-plugin

[dmp1ce]

Thank you. Forking is probably for the best at this point.
