Interface Dependency

All Superinterfaces:

Artifact

All Known Subinterfaces:

DownloadedDependency

All Known Implementing Classes:

DefaultDependency

@Experimental
@Immutable
public interface Dependency
extends Artifact

A result of collecting, flattening and resolving DependencyCoordinatess. Dependency is the output of the collection process, which builds the graph of dependencies, followed by flattening and resolution. The version selection is done for each dependency during the collection phase. The flatten phase will keep only a single version per (groupId, artifactId) pair. The resolution will actually download the dependencies (or artifacts) that have been computed.

Since:

4.0.0

Method Summary

Modifier and Type	Method	Description

Method Details

getType

@Nonnull
Type getType()

Returns the type of the dependency. A dependency can be a JAR file, a modular-JAR if it is intended to be placed on the module-path, a JAR containing test classes, etc.

Returns:

the type of the dependency

See Also:

• DependencyCoordinates.getType()

getScope

@Nonnull
DependencyScope getScope()

Returns the time at which the dependency will be used. If may be, for example, at compile time only, at run time or at test time.

Returns:

the time at which the dependency will be used

See Also:

• DependencyCoordinates.getScope()

isOptional

boolean isOptional()

Returns whether the dependency is optional or mandatory. Contrarily to DependencyCoordinates, the obligation of a Dependency is always present. The value is computed during the dependencies collection phase.

Returns:

true if the dependency is optional, or false if mandatory

See Also:

• DependencyCoordinates.getOptional()

toCoordinates

@Nonnull
DependencyCoordinates toCoordinates()

Returns coordinates with the same identifiers as this dependency.

Specified by:

toCoordinates in interface Artifact

Returns:

coordinates with the same identifiers as this dependency
