  • Method Details

    • getArtifact

      public Artifact getArtifact()
      Gets the artifact being depended on.
      Returns:
      The artifact, never null.

    • setArtifact

      public Dependency setArtifact(Artifact artifact)
      Sets the artifact being depended on.
      Parameters:
      artifact - The artifact, must not be null.
      Returns:
      The new dependency, never null.

    • getScope

      public String getScope()
      Gets the scope of the dependency. The scope defines in which context this dependency is relevant.
      Returns:
      The scope or an empty string if not set, never null.

    • setScope

      public Dependency setScope(String scope)
      Sets the scope of the dependency, e.g. "compile".
      Parameters:
      scope - The scope of the dependency, may be null.
      Returns:
      The new dependency, never null.

    • isOptional

      public boolean isOptional()
      Indicates whether this dependency is optional or not. Optional dependencies can be ignored in some contexts.
      Returns:
      true if the dependency is (definitively) optional, false otherwise.

    • getOptional

      public Boolean getOptional()
      Gets the optional flag for the dependency. Note: Most clients will usually call isOptional() to determine the optional flag, this method is for advanced use cases where three-valued logic is required.
      Returns:
      The optional flag or null if unspecified.

    • setOptional

      public Dependency setOptional(Boolean optional)
      Sets the optional flag for the dependency.
      Parameters:
      optional - true if the dependency is optional, false if the dependency is mandatory, may be null if unspecified.
      Returns:
      The new dependency, never null.

    • getExclusions

      public Collection<Exclusion> getExclusions()
      Gets the exclusions for this dependency. Exclusions can be used to remove transitive dependencies during resolution.
      Returns:
      The (read-only) exclusions, never null.

    • setExclusions

      public Dependency setExclusions(Collection<Exclusion> exclusions)
      Sets the exclusions for the dependency.
      Parameters:
      exclusions - The exclusions, may be null.
      Returns:
      The new dependency, never null.
