Interface DependencyCollector

All Superinterfaces:

Service

@Experimental

Since:

4.0

Method Details

collect

@Nonnull
DependencyCollectorResult collect(@Nonnull
 DependencyCollectorRequest request)

Collects the transitive dependencies and builds a dependency graph. Note that this operation is only concerned about determining the coordinates of the transitive dependencies and does not actually resolve the artifact files.

Parameters:

request - the dependency collection request, must not be null

Returns:

the collection result, never null

Throws:

DependencyCollectorException - if the dependency tree could not be built

IllegalArgumentException - if an argument is null or invalid

collect

@Nonnull
default DependencyCollectorResult collect(@Nonnull
 Session session,
 @Nonnull

Parameters:

session - the Session, must not be null

root - the Maven Dependency, must not be null

Returns:

the collection result, never null

Throws:

DependencyCollectorException - if the dependency tree could not be built

IllegalArgumentException - if an argument is null or invalid

default DependencyCollectorResult collect(@Nonnull
 Session session,
 @Nonnull
 Project project)
