Ant User Manual

Copy

Description

Copies a file or Fileset to a new file or directory. Files are only copied if the source file is newer than the destination file, or when the destination file does not exist. However, you can explicitly overwrite files with the overwrite attribute.

FileSets are used to select files to copy. To use a fileset, the todir attribute must be set.

Parameters

Attribute	Description	Required
file	The file to copy.	One of either `file` or at least one nested fileset element.
preservelastmodified	Give the copied files the same last modified time as the original files. Defaults to "no".	No
tofile	The file to copy to.	With the `file` attribute, either `tofile` or `todir` can be used. With nested filesets, only `todir` is allowed.
todir	The directory to copy to.
overwrite	Overwrite existing files even if the destination files are newer. Defaults to "no".	No
filtering	Indicates whether token filtering using the global build file filters should take place during the copy. Defaults to "no". Nested filtersets will be used even if this value is "no"	No
flatten	Ignore directory structure of source directory, copy all files into a single directory, specified by the `todir` attribute. Defaults to "no". Note that you can achieve the same effect by using a flatten mapper	No
includeEmptyDirs	Copy empty directories included with the nested FileSet(s). Defaults to "yes".	No

Parameters specified as nested elements

fileset

FileSets are used to select files to copy. To use a fileset, the todir attribute must be set.

mapper

You can define file name transformations by using a nested mapper element. The default mapper used by <copy> is the identity.

filterset

Filtersets are used to replace tokens in files that are copied. To use a filterset just add the nested filterset elements.

  <copy todir="../dest/dir" >
    <fileset dir="src_dir" excludes="**/*.java"/>
