/**
* <p>
* This component will build some {@link MavenReportExecution} from {@link MavenReportExecutorRequest}.
* If a {@link MavenReport} needs to fork a lifecycle, this fork is executed here.
* It will ask the core to get some informations in order to correctly setup {@link MavenReport}.
* </p>
* <p>
* <b>Note</b> if no version is defined in the report plugin, the version will be searched
* with method {@link #resolvePluginVersion(ReportPlugin, MavenReportExecutorRequest)}
* Steps to find a plugin version stop after each step if a non <code>null</code> value has been found:
* <ol>
* <li>use the one defined in the reportPlugin configuration,</li>
* <li>search similar (same groupId and artifactId) mojo in the build/plugins section of the pom,</li>
* <li>search similar (same groupId and artifactId) mojo in the build/pluginManagement section of the pom,</li>
* <li>ask {@link PluginVersionResolver} to get a fallback version and display a warning as it's not a recommended use.</li>
* </ol>
* </p>
* <p>
* Following steps are done:
* <ul>
* <li>get {@link PluginDescriptor} from the {@link MavenPluginManager#getPluginDescriptor(Plugin, RepositoryRequest, RepositorySystemSession)}</li>
* <li>setup a {@link ClassLoader} with the Mojo Site plugin {@link ClassLoader} as parent for the report execution.
* You must note some classes are imported from the current Site Mojo ClassRealm: see {@link #IMPORTS}.
* The artifact resolution excludes the following artifacts, corresponding to imported classes:
* doxia-site-renderer, doxia-sink-api, maven-reporting-api.
* Done using {@link MavenPluginManager#setupPluginRealm(PluginDescriptor, MavenSession, ClassLoader, List, DependencyFilter)}
* </li>
* <li>
* setup the mojo using {@link MavenPluginManager#getConfiguredMojo(Class, MavenSession, MojoExecution)}
* </li>
* <li>
* verify with {@link LifecycleExecutor#calculateForkedExecutions(MojoExecution, MavenSession)}
* if any forked execution is needed: if yes, executes the forked execution here
* </li>
* </ul>
