commented
**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: ```none
git clone URL
```
However, git supports checking out only the latest version of the code base,
using this command: ```none
git clone --depth 1 URL
```
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` will:
- _significantly_ improve performance on larger repositories and/or with a
lot of history
- and reduce I/O on repositories with a lot of history.
