-------------------------------------
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.
