getSortedProjects

List<MavenProject> getSortedProjects()

Gets all projects in their intended build order, i.e. after topologically sorting the projects according to their inter-dependencies.

Returns:

The projects in the build order, never null.

getDownstreamProjects

List<MavenProject> getDownstreamProjects(MavenProject project,
                                         boolean transitive)

Gets the downstream projects of the specified project. A downstream project is a project that directly or indirectly depends on the given project.

Parameters:

project - The project whose downstream projects should be retrieved, must not be null.

transitive - A flag whether to retrieve all direct and indirect downstream projects or just the immediate downstream projects.

Returns:

The downstream projects in the build order, never null.

getUpstreamProjects

List<MavenProject> getUpstreamProjects(MavenProject project,
                                       boolean transitive)

Gets the upstream projects of the specified project. An upstream project is a project that directly or indirectly is a prerequisite of the given project.

Parameters:

project - The project whose upstream projects should be retrieved, must not be null.

transitive - A flag whether to retrieve all direct and indirect upstream projects or just the immediate upstream projects.

Returns:

The upstream projects in the build order, never null.
