Enum DuplicatesStrategy

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Comparable<DuplicatesStrategy>

    public enum DuplicatesStrategy
    extends java.lang.Enum<DuplicatesStrategy>
    Strategies for dealing with the potential creation of duplicate files or archive entries.
    • Enum Constant Summary

      Enum Constants 
      Enum Constant Description
      EXCLUDE
      Do not allow duplicates by ignoring subsequent items to be created at the same path.
      FAIL
      Throw a DuplicateFileCopyingException when subsequent items are to be created at the same path.
      INCLUDE
      Do not attempt to prevent duplicates.
      INHERIT
      The default strategy, which is to inherit the strategy from the parent copy spec, if any, or INCLUDE if the copy spec has no parent.
      WARN
      Do not attempt to prevent duplicates, but log a warning message when multiple items are to be created at the same path.

      static DuplicatesStrategy valueOf​(java.lang.String name)
      Returns the enum constant of this type with the specified name.
      static DuplicatesStrategy[] values()
      Returns an array containing the constants of this enum type, in the order they are declared.

      • INCLUDE

        public static final DuplicatesStrategy INCLUDE
        Do not attempt to prevent duplicates.

        If the destination of the operation supports duplicates (e.g. zip files) then a duplicate entry will be created. If the destination does not support duplicates, the existing destination entry will be overridden with the duplicate.

      • EXCLUDE

        public static final DuplicatesStrategy EXCLUDE
        Do not allow duplicates by ignoring subsequent items to be created at the same path.

        If an attempt is made to create a duplicate file/entry during an operation, ignore the item. This will leave the file/entry that was first copied/created in place.

      • WARN

        public static final DuplicatesStrategy WARN
        Do not attempt to prevent duplicates, but log a warning message when multiple items are to be created at the same path.

        This behaves exactly as INCLUDE otherwise.

      • FAIL

        public static final DuplicatesStrategy FAIL
        Throw a DuplicateFileCopyingException when subsequent items are to be created at the same path.

        Use this strategy when duplicates are an error condition that should cause the build to fail.

      • INHERIT

        public static final DuplicatesStrategy INHERIT
        The default strategy, which is to inherit the strategy from the parent copy spec, if any, or INCLUDE if the copy spec has no parent.

      • values

        public static DuplicatesStrategy[] values()
        Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
        for (DuplicatesStrategy c : DuplicatesStrategy.values())
            System.out.println(c);
        
        Returns:
        an array containing the constants of this enum type, in the order they are declared
      • valueOf

        public static DuplicatesStrategy valueOf​(java.lang.String name)
        Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
        Parameters:
        name - the name of the enum constant to be returned.
        Returns:
        the enum constant with the specified name
        Throws:
        java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
        java.lang.NullPointerException - if the argument is null
