Cleans a directory without deleting it.

Parameters:

forceDelete

public static void forceDelete(java.io.File file)
                        throws java.io.IOException

Deletes a file. If file is a directory, delete it and all sub-directories.

The difference between File.delete() and this method are:

• You get exceptions when a file or directory cannot be deleted. (java.io.File methods returns a boolean)

Parameters:

file - file or directory to delete, must not be null

Throws:

java.lang.NullPointerException - if the directory is null

java.io.IOException - in case deletion is unsuccessful

                                               java.lang.String target)

Return relative path.

WARNING:
Folder path must finished with the character: File.separator

Example:

source	target	relative path
/root/dir1/dir2/	/root/dir1/	../
/root/	/root/dir1/dir2/	dir1/dir2/
/root/dir1/dir2/	/root/test.xml	../../test.xml

Parameters:

source - path of the source folder

target - path of the target folder/file

Returns:

the relative path
