Why Bitbucket souce code repository not getting cloned using Jenkins? - jenkins

Question

I am using latest Jenkins in my Linux box. I am trying to clone a Bitbucket repository and checkout master branch using Jenkins pipeline. What I am trying to achieve is, after getting my source code cloned, I can make use of it and proceed with build. Below is my code;
node {
stage('Build') {
git branch: 'master',
credentialsId: '12345678-1234-1234-1234-123456789123',
url: 'https://username#bitbucket.org/username/test.git'
}
stage('Test') {
sh """pwd"""
}
}
and below is my console output;

When I cd to /var/lib/jenkins/workspace/test_pipeline I can see nothing. Why is this happening?
