| /** |
| * A build context that matches a Maven project to a given task segment, and the session to be used. |
| * <p> |
| * A note to the reader; |
| * </p> |
| * <p> |
| * There are several issues/discussions regarding how "aggregator" plugins should be handled. |
| * Read for instance http://docs.codehaus.org/display/MAVEN/Deterministic+Lifecycle+Planning |
| * </p> |
| * <p> |
| * In their current implementation they are "bolted" onto the lifecycle by separating them |
| * into TaskSegments. This class represents the execution context of one such task segment. |
| * </p> |
| * <p> |
| * Wise voices have suggested that maybe aggregators shouldn't be bound to the ordinary |
| * lifecycle at all, in which case we wouldn't be needing this class at all ( and |
| * ProjectBuildList.getByTaskSegments). Or maybe they should be introduced in the calculation |
| * of the execution plan instead, which seems much nicer. |
| * </p> |
| * <p> |
| * Additionally this class contains a clone of the MavenSession, which is *only* needed |
| * because it has as notion of a "current" project. |
| * </p> |
| * <strong>NOTE:</strong> This class is not part of any public api and can be changed or deleted without prior notice. |

| * @since 3.0 |
