Thank you for your post into the forum post.
Sadly GIT is not supported at this moment in time. If you have not already done so, I recommend that you comment and vote in this User Voice FORUM
for our Oracle tools. The product managers and development teams actively monitor the user voice forums. This topic has already received a large number of votes, so I will check with the Source Control for Oracle Product Manager to see if this feature is on the road map for a future version of our application.
