-----------------------------------
Summary: Store snapshots in a separate local repository
Key: MNG-6270
URL: https://issues.apache.org/jira/browse/MNG-6270
Project: Maven
Issue Type: New Feature
Components: Artifacts and Repositories, Settings
Reporter: Joern Gebhardt
h2. Requested Feature
As already suggested in MNG-4481 it would be really helpful if Maven was able
to store the Snapshot artifacts in a different location than the fixed version
ones.
Technically it could be configured like this:
{code}
<settings>
<snapshotLocalRepository>${user.home}/.m2/snapshots</snapshotLocalRepository>
...
</settings>
{code}
or via a new Maven property {{maven.repo.local.snapshot}}.
h2. Uses Cases
# *Feature Branch Development Support*: When using a branching model like
[Vincent Driessen's
Gitflow|http://nvie.com/posts/a-successful-git-branching-model] or [Adam Ruka's
Oneflow|http://endoflineblog.com/oneflow-a-git-branching-model-and-workflow]
you do feature development in parallel branches that get merged back into the
{{master}} when the feature is completed.
However, these feature branches produce the same snapshot artifact version. On
a central build server it is necessary that these snapshot artifacts are only
visible within one feature branch and cannot be seen from a different feature
branch as they are potentially incompatible.
Currently it is only possible to use different fully fledged local repositories
for each feature branch, however, this slows down the first builds as the fixed
versions artifacts have to be copied into the feature-branch specific local
repository. Additionally, it costs a lot of disk space.
Having the possibility to uses feature-branch specific repositories for the
snapshot dependencies only, would be a great feature for a development process
using feature branches.
# Drop all snapshots and make clean build (no ancient snapshot dependencies
will bass) - useful especially after changing module identification.
