Usage

From source file:org.apache.maven.plugins.linkcheck.SiteInvoker.java

/**
 * Invoke Maven for the <code>site</code> phase for a temporary Maven project using
 * <code>tmpReportingOutputDirectory</code> as <code>${project.reporting.outputDirectory}</code>.
 * This is a workaround to be sure that all site files have been correctly generated.
 * <br/>/*from  w ww.java  2s  . co  m*/
 * <b>Note 1</b>: the Maven Home should be defined in the <code>maven.home</code> Java system property
 * or defined in <code>M2_HOME</code> system env variables.
 * <b>Note 2</be>: we can't use <code>siteOutputDirectory</code> param from site plugin because some plugins
 * <code>${project.reporting.outputDirectory}</code> in their conf.
 *
 * @param project the MavenProject to invoke the site on. Not null.
 * @param tmpReportingOutputDirectory not null
