I had a git repo on bitbucket with a project. Then I decided to completely rewrite the project from scratch. Now, I have a clean working new version of the project I would push it to bitbucked but it say to me that there are merging conflits since the two repo doesn't have a common history... I have been able to push new version to a different branch but I want that branch to be the master so that it represents the main development history. How can I push a new project to master?
Assuming you have a remote to bitbucket called bitbucket, and you are on the branch you want to be pushed to master, you could force push like this:
git push -f bitbucket master
