>                 Key: MRELEASE-853
>                 URL: https://jira.codehaus.org/browse/MRELEASE-853
>             Project: Maven Release Plugin
>          Issue Type: New Feature
>          Components: Git
>    Affects Versions: 2.2.2
>         Environment: Maven 3.1.1
>            Reporter: Ernst de Haan
>
> *Executive summary: Please use {{--depth 1}} when checking out from a git repository.*
> Currently when doing {{mvn release:prepare release:perform}}, the git checkout step takes a significant amount of time.
> During the git checkout it appears to not only check out the correct version of the code, but also _all_ history, as would be done with a regular: {code:none}git clone URL{code}
> However, git supports checking out only the latest version of the code base, using this command: {code:none}git clone --depth 1 URL{code}
> For the purpose of the Maven Release Plugin, that should be sufficient, as far as I can see.
> Changing the plugin to use {{--depth 1}} would significantly improve performance and reduce I/O on repositories with a lot of history.
