> Use "git --depth 1" When Checking Out
> -------------------------------------
>
> 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.
