THIS IS A TEST INSTANCE. ALL YOUR CHANGES WILL BE LOST!!!!

Creating a repository where the users can deploy their artifacts and once the testing tasks are completed, a user can deploy the artifact to the common place where the we can use those artifacts as dependencies in pom POM files or remove the artifact from the temporary repository if it fails during the testing phase.
Proposal
Apache archiva Archiva is a repository management system where we can deploy our artifacts to a common location and later on we can make use of those artifacts (jar files, war files, zip files, ear files, etc.) in our projects by adding the artifacts as dependencies in the POM file. But here there is no any separate place to deploy the artifacts which are are not tested yet and also the artifacts of an ongoing project(modules).So we need to deploy them in to the common location where the official artifacts are deployed. So there can be some issues due to the use of those artifacts as dependencies in our projects since they are not properly tested.
So here my idea is to create a separate place (repositories) where the registered user can deploy the staging artifacts. Those artifacts are not visible to common users. Once the testing task is completed (ready for the public deployment), we can either merge in them to the common place where others can make use of those artifacts or remove them from the staging artifactarea (if it fails).
Description
First i I would like to give a brief introduction about my approach to adding the staging repository feature.
Adding a Staging Repository
currently archiva Currently, Archiva has two permanent repositories called internal and the snapshotsnapshots. Here, my idea is to propose an intermediate staging repository to deploy artifacts which have not been not tested yet. It is the archiva Archiva user's task to create this permanent staging repository and attached attach it for a selected repository. Following The following example will illustrate that scenario.
Lets Let's say the user has a repository called “data_repo” and he needs to get the support of staging repository. Then he has to create staging repository instance called “data_repo_stage” and he can attached attach this stage repository to his main repository called “data_repo”. (I hope to offer this function through the web interface). Here, user can add more than one stage repositories repository so that simultaneous releasing function will supportbe supported. Promotion is done through the following path.
...
I think in the stage repository we should limit the access. Nobody should allow to download the artifacts in the staging repositories other than the developers, QA people, archiva Archiva admin user, and the the guy who have the permission for the promotion.
Here, for the QA, promotion and the developers i , I am going to use current archiva Archiva roles (Repository Manager and Repository Observer) and assign the permission for them.
...
Read and Write access to the repository
Here, registered users can read and write artifacts to the repository. Here , where registered users mean developers and the QA people. Here, developers should have both read and write access while the QA guys have only the read access. Also QA guys should be able to mark the artifact as success one or a failure onone. Then it will be useful for the merging part to take a correct decision.
Promotion of the Artifacts (merging to the common place)
This is the most important part in this project. Once the testing tasks are done, this role is responsible for merge merging artifacts from staging repository to the internal repository or the snapshot repository. It depends on the artifact(snapshot or a version). Here i I am going to consider the following things regarding the merging the artifacts:
- If the
...
- artifact that
...
- is going to
...
- be deployed is not an existing one (new one), just deploy it with creating new meta data file. (
...
- User should
...
- be able to merge the artifact by clicking the merge button and then should receive
...
- a success/failure message from the
...
- Archiva side)
- If the artifact is an existing one (in the case of re-release), we need to provide following options
...
- :
...
- When the user clicks merge button (in the case of re-release), it should notify the user about the existing version in the release repository.(eg : version number + updated date).
...
- Then we need to suggest to him the following options
...
- :
- skip the re-release
- merge the artifact while removing the older one. Here we should only allow the user to remove the latest artifact.
- Meanwhile, metadata updating should also be done.
- :
In above, I have mentioned only the success scenario of a an artifact. There can be a fail scenario as well. If an artifact is failed then the user should manually delete the artifact
...
- add stage repository function so that user can create a stage repository and attach it to articular released repositoriesa particular release repository. (this This functionality is granted only for the admin level users). Proper UI should e be provide to the user.
- restricted restrict this staging repository from being using used as a plugging repository from out user as mentioned in the pom.xml files
- implementing implement the read action and the write actions and assign them to existing roles.
(Repository Manager and Repository Observer) - implementing implement the promotion role. (only Only the merging based on the assumption that a new artifact is being deployed. Not a update an updated version)
- implement a searching algorithm to check the older version of the artifact which have already been deployed.
- add searching feature (action) to the promotion role and do the merging part by providing the options regarding the version as mentioned above . (with a proper UI). Here meta data , metadata updating should be done.
- implementing implement logs for staging repository
...
- add the simultaneous deployment functionality for the stage repositories. (here Here, need to find a way to check with repository is busy with being a deployment)
