Creating New Composite Project On Git/Bitbucket: Error

I want to create a new project inside a repository which already exist, something line this:

https://bitbucket.org/xxxxxxx/soapuitest

Now i am trying to create a new composite project inside this repository from SOAP UI. But when i try to go via option 'Save and Share project' and give repository url and username/pass, this is not working. It gives me error saving not a git repository but that too its trying to search .git inside the project which i want to create new and this will never happen when i dont have any project...

Mon Jan 22 23:40:42 CET 2018:ERROR:java.lang.IllegalStateException: No git repo exist in: C:\shared\Test-Project\soapuitest\Project-1-readyapi-project
   java.lang.IllegalStateException: No git repo exist in: C:\shared\Test-Project\soapuitest\Project-1-readyapi-project

So should we have 1 repository for 1 project, if not then please let me know how can i create multiple project from soap ui in same repo.
