Clone GitLab project
You can clone a project that you want to contribute to directly from IntelliJ IDEA and create a new project based on it.
Before cloning a project, make sure you have logged in to your GitLab account.
Use one of the options to open the Get from Version Control dialog:
On the Welcome screen, click the Get from VCS button.
Specify the URL of the project you want to clone.
In the Directory field, enter the path to the folder where your local Git project will be created.
