 * execute once, regardless of the number of project instances in the
 * current build. Mojos that are marked as aggregators should use the
 * ${reactorProjects} expression to retrieve a list of the project
 * instances in the current build.
 * If the mojo is not marked as an aggregator (this is the defaut value
 * false in maven), it will be executed once for each project instance in the
