- - ### Method Detail

    - #### toId

          public static String toId(Artifact artifact)

      Creates an artifact identifier of the form `<groupId>:<artifactId>:<extension>[:<classifier>]:<version>`.
      Parameters:
        `artifact` - The artifact to create an identifer for, may be `null`.
      Returns:
        The artifact identifier or `null` if the input was `null`.

    - #### toId

          public static String toId(String groupId,
                    String artifactId,
                    String extension,
                    String classifier,
                    String version)

      Creates an artifact identifier of the form `<groupId>:<artifactId>:<extension>[:<classifier>]:<version>`.
      Parameters:
        `groupId` - The group id, may be `null`.
        `artifactId` - The artifact id, may be `null`.
        `extension` - The file extensiion, may be `null`.
        `classifier` - The classifier, may be `null`.
        `version` - The version, may be `null`.
      Returns:
        The artifact identifier, never `null`.

    - #### toBaseId

          public static String toBaseId(Artifact artifact)

      Creates an artifact identifier of the form `<groupId>:<artifactId>:<extension>[:<classifier>]:<baseVersion>`.
      Parameters:
        `artifact` - The artifact to create an identifer for, may be `null`.
      Returns:
        The artifact identifier or `null` if the input was `null`.

    - #### toVersionlessId

          public static String toVersionlessId(Artifact artifact)

      Creates an artifact identifier of the form `<groupId>:<artifactId>:<extension>[:<classifier>]`.
      Parameters:
        `artifact` - The artifact to create an identifer for, may be `null`.
      Returns:
        The artifact identifier or `null` if the input was `null`.

    - #### toVersionlessId

          public static String toVersionlessId(String groupId,
                               String artifactId,
                               String extension,
                               String classifier)

      Creates an artifact identifier of the form `<groupId>:<artifactId>:<extension>[:<classifier>]`.
      Parameters:
        `groupId` - The group id, may be `null`.
        `artifactId` - The artifact id, may be `null`.
        `extension` - The file extensiion, may be `null`.
        `classifier` - The classifier, may be `null`.
      Returns:
        The artifact identifier, never `null`.

    - #### equalsId

          public static boolean equalsId(Artifact artifact1,
                         Artifact artifact2)

      Determines whether two artifacts have the same identifier. This method is equivalent to calling `String.equals(Object)` on the return values from `toId(Artifact)` for the artifacts but does not incur the overhead of creating temporary strings.
      Parameters:
        `artifact1` - The first artifact, may be `null`.
        `artifact2` - The second artifact, may be `null`.
      Returns:
        `true` if both artifacts are not `null` and have equal ids, `false` otherwise.

    - #### equalsBaseId

          public static boolean equalsBaseId(Artifact artifact1,
                             Artifact artifact2)

      Determines whether two artifacts have the same base identifier. This method is equivalent to calling `String.equals(Object)` on the return values from `toBaseId(Artifact)` for the artifacts but does not incur the overhead of creating temporary strings.
      Parameters:
        `artifact1` - The first artifact, may be `null`.
        `artifact2` - The second artifact, may be `null`.
      Returns:
        `true` if both artifacts are not `null` and have equal base ids, `false` otherwise.
