Class DefaultMavenReportExecutor

java.lang.Object

org.apache.maven.reporting.exec.DefaultMavenReportExecutor

All Implemented Interfaces:

MavenReportExecutor

@Component(role=MavenReportExecutor.class)
public class DefaultMavenReportExecutor
extends Object
implements MavenReportExecutor

This component will build some MavenReportExecution from MavenReportExecutorRequest. If a 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 MavenReport.

Note if no version is defined in the report plugin, the version will be searched with resolvePluginVersion(...) method:

1. use the one defined in the reportPlugin configuration,
2. search similar (same groupId and artifactId) plugin in the build/plugins section of the pom,
3. search similar (same groupId and artifactId) plugin in the build/pluginManagement section of the pom,
4. ask PluginVersionResolver to get a fallback version (display a warning as it's not a recommended use).

Following steps are done:

• get PluginDescriptor from the MavenPluginManager (through MavenPluginManagerHelper.getPluginDescriptor(...) to protect from core API change)
• setup a ClassLoader, with the Site plugin classloader as parent for the report execution.
  Notice that some classes are imported from the current Site plugin ClassRealm: see IMPORTS. Corresponding artifacts are excluded from the artifact resolution: doxia-site-renderer, doxia-sink-api and maven-reporting-api.
  Work is done using MavenPluginManager (through MavenPluginManagerHelper.setupPluginRealm(...) to protect from core API change)
• setup the mojo using MavenPluginManager.getConfiguredMojo(...)
• verify with LifecycleExecutor.calculateForkedExecutions(...) if any forked execution is needed: if yes, execute the forked execution here

                                             throws org.apache.maven.plugin.MojoExecutionException

Description copied from interface: MavenReportExecutor

Build the MavenReports, with associated forked executions if necessary.

Specified by:

buildMavenReports in interface MavenReportExecutor

Parameters:

mavenReportExecutorRequest - the request

Returns:

a list or prepared Maven report executions

Throws:

org.apache.maven.plugin.MojoExecutionException - on report execution issue

buildReportPlugin

protected List<MavenReportExecution> buildReportPlugin(MavenReportExecutorRequest mavenReportExecutorRequest,
                                                       org.apache.maven.reporting.exec.ReportPlugin reportPlugin)

Exception

resolvePluginVersion

protected String resolvePluginVersion(org.apache.maven.reporting.exec.ReportPlugin reportPlugin,
                                      MavenReportExecutorRequest mavenReportExecutorRequest)
                               throws org.apache.maven.plugin.version.PluginVersionResolutionException

Resolve report plugin version. Steps to find a plugin version stop after each step if a non null value has been found:

1. use the one defined in the reportPlugin configuration,
2. search similar (same groupId and artifactId) mojo in the build/plugins section of the pom,
3. search similar (same groupId and artifactId) mojo in the build/pluginManagement section of the pom,
4. ask PluginVersionResolver to get a fallback version and display a warning as it's not a recommended use.

Parameters:

reportPlugin - the report plugin to resolve the version

mavenReportExecutorRequest - the current report execution context

Returns:

the report plugin version

Throws:

org.apache.maven.plugin.version.PluginVersionResolutionException - on plugin version resolution issue
