Build a Quickstarts verification tool

Some requirements:

• Validating quickstart POM files:
  • OK Check for the License header (checkstyle headers) - OK Headers templates must be updated: https://github.com/jboss/ide-config/pull/6
  • OK Check for proper spacing and Indentation (try checkstyle - whitespace rule and indentation rule)
  • OK Check and verify if all quickstarts are using the same/latest BOM versions
  • OK Verify is it using the standard properties names (We will provide the standard properties name)
  • OK Check for non bom versions (and identify if we should create a new BOM)
  • Check javascript and css versions
  • OK Check for duplicate properties and dependencies
  • OK Check for unused properties on project and its modules
  • OK Check the pom.xml elements order
  • Create scripts to update versions (quickstart, boms, etc)
  • OK When a new quickstart is added, if it has a pom.xml file, make sure the <module> is defined in one of the following profiles: default, requires-postgres, complex-dependencies, requires-full, requires-xts, non-maven.
  • OK Check if all dependencies are in central (the issue that was discussed in JDF-206).
  • OK Check for a `<finalName>${project.artifactId}</finalName>` in the file to prevent appending version numbers to archives.
  • OK Check for the apache license
  • OK Check if project groupId is 'org.jboss.as.quickstarts'

• Validating quickstart README files:
  • OK Check for the required metadata tags in README (Level, Author, Target Product, etc)
  • OK Verify the quickstart name in the README matches the folder name and the project name

• Validating quickstart source code
  • Check the quantity of comments in the code (evaluate PMD)

• General validation (desired):
  • If a quickstart with a source other than the current repository is modified, create an alert of some sort so we can notify the upstream repository of the change.
  • When we update a BOM property version in the quickstarts, we need to make the same changes in the archetypes.
  • Also, if there is a code fix in the kitchensink or kitchensink-ear, we need to make the same fix in the archetype code and check other quickstarts based on the same archetype to see if they need the fixes applied.
