Attempt to push changes for the same repository in multiple environments of the same deployment project will lead to error in most of them.

Steps to Reproduce

1. Create a build plan
2. Create a deployment plan and associate to that build plan
3. Create 2 environments with the following tasks:
   1. Checkout task - to checkout a 'dummie repository' (it does not need to be the same repository used in the plan)
   2. Script task - to add changes in this repository
   3. Commit task - to commit the changes
   4. Push task - to push the changes
4. Add an after successful build plan trigger in the environment 1
5. Add an after successful deployment trigger in the environment 2
6. run the build plan

Expected Results

1. Environment 1 will be trigger after the build and will succeed.
2. Environment 2 will be triggered after environment 1 and will succeed.

Actual Results

1. Environment 1 will be trigger after the build and will succeed.
2. Environment 2 will be triggered after environment 1 and will fail with the following stack trace:

Workaround

Add a script task with a git pull after the git checkout task.
