DuplicatesStrategy (Gradle API 8.11)

Package org.gradle.api.file

## Enum DuplicatesStrategy

- java.lang.Object
- - java.lang.Enum<DuplicatesStrategy>
  - - org.gradle.api.file.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.

  - ### Method Summary

    All Methods Static Methods Concrete Methods
    Modifier and Type | Method | Description
    --- | --- | ---
    `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.

- - ### Enum Constant Detail

    - #### 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.
      Since:
        5.0

  - ### Method Detail

    - #### 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
