  - ### Method Detail

    - #### getGroup

          @Nullable
          String getGroup()

      Returns the group of this dependency. The group is often required to find the artifacts of a dependency in a repository. For example, the group name corresponds to a directory name in a Maven like repository. Might return null.

    - #### getName

          String getName()

      Returns the name of this dependency. The name is almost always required to find the artifacts of a dependency in a repository. Never returns null.

    - #### getVersion

          @Nullable
          String getVersion()

      Returns the version of this dependency. The version is often required to find the artifacts of a dependency in a repository. For example the version name corresponds to a directory name in a Maven like repository. Might return null.

    - #### contentEquals

          boolean contentEquals​(Dependency dependency)

      Returns whether two dependencies have identical values for their properties. A dependency is an entity with a key. Therefore dependencies might be equal and yet have different properties.
      Parameters:
        `dependency` - The dependency to compare this dependency with

    - #### copy

          Dependency copy()

      Creates and returns a new dependency with the property values of this one.
      Returns:
        The copy. Never returns null.

          @Incubating
          @Nullable
          String getReason()

      Returns a reason why this dependency should be used, in particular with regards to its version. The dependency report will use it to explain why a specific dependency was selected, or why a specific dependency version was used.
      Returns:
        a reason to use this dependency
      Since:
        4.6
