title: maven release plugin fails with timeout from git
body: <p>I get the below error while doing mvn release:perform. Seems like its a timeout issue while cloning the project into target/checkout folder. Am not sure how to solve the issue.
  I did git clone manually and it worked but through mvn release plugin it fails with below error.
  Any help would be appreciated!!</p>
