             Summary: [slingfeature-m-p] donate a new MOJO which is able to scan and detect differences between different versions of the same Feature model
                 Key: SLING-8468
                 URL: https://issues.apache.org/jira/browse/SLING-8468
             Project: Sling
          Issue Type: New Feature
          Components: Feature Model, Maven Plugins and Archetypes
    Affects Versions: slingfeature-maven-plugin 1.0.2
            Reporter: Simone Tripodi
            Assignee: Simone Tripodi
             Fix For: slingfeature-maven-plugin 1.0.4


I would like to donate a new {{features-diff}} MOJO I developed in the spare time that could be helpful detecting systems evolution.
I got inspiration from my previous contribution of the [Felix Baseline|https://felix.apache.org/components/bundle-plugin/baseline-mojo.html] MOJO, users can configure the feature selection (inherited by the {{AbstractIncludingFeatureMojo}}) and the previously released version of the they are interested comparing, i.e.:

{noformat}
          <plugin>
            <groupId>org.apache.sling</groupId>
            <artifactId>slingfeature-maven-plugin</artifactId>
            <executions>
              <execution>
                <id>features-diff</id>
                <phase>package</phase>
                <goals>
                  <goal>features-diff</goal>
                </goals>
                <configuration>
                  <comparisonVersion>1.0.2</comparisonVersion>
                  <selection>
                    <includeClassifier>cloud-ready</includeClassifier>
                    <includeClassifier>base</includeClassifier>
                  </selection>
{noformat}

then the plugin will take care of resolving the configured version of selected classified Feature and compare each other, producing the outputs in the {{target/features-diff/<classifier>.diff.json}} files, enlisting for each Feature section what was added/removed/changed.

The new MOJO relies on the [Feature Model API Regions model|https://github.com/apache/sling-org-apache-sling-feature-apiregions-model] and the [Feature Diff|https://github.com/apache/sling-whiteboard/tree/master/feature-diff] (still in the whiteboard) which contains the core implementation of the diff tool.

I will start pushing the MOJO in a separated branch in order to discuss the development evolution.
