Cloning Azure DevOps repositories with SourceTree could be a complicated task.
For those having authentication or "..not valid source path.." issues, the following information might be of your interest.
** Do not create an account in SourceTree for this repository, let it be created automatically **
I usually follow the second approach because I have Git already installed
Approach 1: Using SourceTree Embedded Git
First of all, verify you have the latest Git embedded version
SourceTree > Tools > Git > Git Version section. Click on Update Embedded
Approach 2: Using System Git
Install Git latest version from GIT homepage
SourceTree > Tools > Git > Git Version section. Click on System
Common procedure: Clone a DevOps branch using SourceTree
In your DevOps repository page, click on Clone and Generate Git credentials
In SourceTree create a new repository tab and select Clone
Copy the DevOps HTTPS Repository Url and paste it into Source Path / URL field in SourceTree clone page.
You will be prompted to select the DevOps integrated user. Go ahead and select it
Configure the Destination Path and Repository Name (tab name) and hit the Clone button
And that's it. SourceTree will clone the selected repository and automatically create the associated account in SourceTree.
