[MINSTALL-177] Streamline the plugin (#32)

Original plugin made hoops and loops, instead to perform what it needed to perform. Partly to blame this was unfinished state of MAT API (it was able to install project only).

Installing project is needed in InstallMojo, but InstallFileMojo was forced to make hoops and loops due this, as it was passed one file (and maybe pomFile), and it was forced to create "fake" project, decorate and fake setup it with all whistle and bells, only to get it via MAT to resolver that would "decompose" it back into set of artifacts needing a deploy. So it went this file-artifact-project-artifact route, that made all the logic fragile and overly complicated.

This PR completely reworks m-install-p making it (almost trivially) simple: it does what it needs to do, without any fuss, and does it in streamlined way: InstallMojo will create a list of artifacts out of project and pass it to repository system for deploy, while InstallFileMojo literally prepares just a deployment request,  nothing more. No fuss, no magic, no fake project building etc.

Note: the code in mojos may or may not need to be reusable, but definitely smells like some "Maven API-ish thing". 

Problems: InstallFileMojo implicitly implemented ID validation (thru fake project building), and it revealed the problem that Maven ID (groupId, artifactId) and version validation is deeply buried into maven-model-builder and is NOT reusable at all, hence a light copy of logic (rules for ID allowed characters and version forbidden characters) are copied over here.

Contributing to Apache Maven Install Plugin

ASF Jira Apache License, Version 2.0, January 2004 Maven Central Jenkins Status Jenkins tests

You have found a bug or you have an idea for a cool new feature? Contributing code is a great way to give something back to the open source community. Before you dig right into the code, there are a few guidelines that we need contributors to follow so that we can have a chance of keeping on top of things.

Getting Started

  • Make sure you have a JIRA account.
  • Make sure you have a GitHub account.
  • If you‘re planning to implement a new feature, it makes sense to discuss your changes on the dev list first. This way you can make sure you’re not wasting your time on something that isn‘t considered to be in Apache Maven’s scope.
  • Submit a ticket for your issue, assuming one does not already exist.
    • Clearly describe the issue, including steps to reproduce when it is a bug.
    • Make sure you fill in the earliest version that you know has the issue.
  • Fork the repository on GitHub.

Making and Submitting Changes

We accept Pull Requests via GitHub. The developer mailing list is the main channel of communication for contributors.
There are some guidelines which will make applying PRs easier for us:

  • Create a topic branch from where you want to base your work (this is usually the master branch). Push your changes to a topic branch in your fork of the repository.
  • Make commits of logical units.
  • Respect the original code style: by using the same codestyle, patches should only highlight the actual difference, not being disturbed by any formatting issues:
    • Only use spaces for indentation.
    • Create minimal diffs - disable on save actions like reformat source code or organize imports. If you feel the source code should be reformatted, create a separate PR for this change.
    • Check for unnecessary whitespace with git diff --check before committing.
  • Make sure your commit messages are in the proper format. Your commit message should contain the key of the JIRA issue.
[MINSTALL-XXX] - Subject of the JIRA Ticket
 Optional supplemental description.
  • Make sure you have added the necessary tests (JUnit/IT) for your changes.
  • Run all the tests with mvn -Prun-its verify to assure nothing else was accidentally broken.
  • Submit a pull request to the repository in the Apache organization.
  • Update your JIRA ticket and include a link to the pull request in the ticket.

If you plan to contribute on a regular basis, please consider filing a contributor license agreement.

Making Trivial Changes

For changes of a trivial nature to comments and documentation, it is not always necessary to create a new ticket in JIRA. In this case, it is appropriate to start the first line of a commit with ‘(doc)’ instead of a ticket number.
