Here is may script:

#!/usr/bin/env bash

DIR=/d/git/eSim.Beneficio
if [ -d "$DIR" ]; then
    printf '%s\n' "Removing Lock ($DIR)"
    rm -rf "$DIR"
fi

#navigate to git directory
cd /d/git/

#clone repo
git clone https://<user>:<password>@mongeral.visualstudio.com/DefaultCollection/Projetos/_git/eSim.Beneficio

cd /d/git/eSim.Beneficio

# Checkout master branch and merge version branch into master
git checkout automaticMergeTest
git merge master --no-ff --no-edit
git push
CURRENT_BRANCH=$(git rev-parse --abbrev-ref HEAD)

# Success
echo "-------------------------------------------------------------------------"
echo "Merge master into $CURRENT_BRANCH complete"

I've ran this script in build server e got success.

Am I doing something wrong?
