All Implemented Interfaces:

Serializable, Comparable<DuplicatesStrategy>

public enum DuplicatesStrategy
extends Enum<DuplicatesStrategy>

Strategies for dealing with the potential creation of duplicate files for 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

Modifier and Type	Method	Description
static DuplicatesStrategy	valueOf(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

@Incubating
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(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:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
