## Delete

### Description

Deletes a single file, a specified directory and all its files and subdirectories, or a set of files specified by one or more resource collections. The literal implication of `<fileset>` is that directories are not included; however the removal of empty directories can be triggered when using nested filesets by setting the `includeEmptyDirs` attribute to true. Note that this attribute is meaningless in the context of any of the various resource collection types that do include directories, but that no attempt will be made to delete non-empty directories in any case. Whether a directory is empty or not is decided by looking into the filesystem - include or exclude patterns don't apply here.

If you use this task to delete temporary files created by editors and it doesn't seem to work, read up on the default exclusion set in Directory-based Tasks, and see the `defaultexcludes` attribute below.

For historical reasons `<delete dir="x"/>` is different from `<delete><fileset dir="x"/></delete>`, it will try to remove everything inside "x" including "x" itself, not taking default excludes into account, blindly following all symbolic links. If you need more control, use a nested `<fileset>`.

### Parameters

Attribute | Description | Required
file | The file to delete, specified as either the simple filename (if the file exists in the current base directory), a relative-path filename, or a full-path filename. | At least one of the two, unless nested resource collections are specified

dir

The directory to delete, including all its files and subdirectories.
Note: `dir` is not used to specify a directory name for `file`; `file` and `dir` are independent of each other.
WARNING: Do not set `dir` to `"."`, `"${basedir}"`, or the full-pathname equivalent unless you truly intend to recursively remove the entire contents of the current base directory (and the base directory itself, if different from the current working directory).

verbose | Whether to show the name of each deleted file. | No, default "false"

quiet

If the specified file or directory does not exist, do not display a diagnostic message (unless Apache Ant has been invoked with the `-verbose` or `-debug` switches) or modify the exit status to reflect an error. When set to "true", if a file or directory cannot be deleted, no error is reported. This setting emulates the `-f` option to the Unix rm command. Setting this to "true" implies setting `failonerror` to "false".

No, default "false"

failonerror | Controls whether an error (such as a failure to delete a file) stops the build or is merely reported to the screen. Only relevant if `quiet` is "false". | No, default "true"
includeemptydirs | Whether to delete empty directories when using filesets. | No, default "false"
includes | Deprecated. Use resource collections. Comma- or space-separated list of patterns of files that must be deleted. All files are relative to the directory specified in `dir`. | No
includesfile | Deprecated. Use resource collections. The name of a file. Each line of this file is taken to be an include pattern. | No
excludes | Deprecated. Use resource collections. Comma- or space-separated list of patterns of files that must be excluded from the deletion list. All files are relative to the directory specified in `dir`. No files (except default excludes) are excluded when omitted. | No
excludesfile | Deprecated. Use resource collections. The name of a file. Each line of this file is taken to be an exclude pattern | No
defaultexcludes | Deprecated. Use resource collections. Whether to use default excludes. | No, default "true"
deleteonexit | Indicates whether to use File#deleteOnExit() if there is a failure to delete a file, this causes the jvm to attempt to delete the file when the jvm process is terminating. Since Ant 1.6.2 | No, default "false"
removeNotFollowedSymlinks | Whether symbolic links (not the files/directories they link to) should be removed if they haven't been followed because followSymlinks was false or the maximum number of symbolic links was too big. Since Ant 1.8.0 | No, default "false"

performGCOnFailedDelete

If Ant fails to delete a file or directory it will retry the operation once. If this flag is set to true it will perform a garbage collection before retrying the delete.
Setting this flag to true is known to resolve some problems on Windows (where it defaults to true) but also for directory trees residing on an NFS share. Since Ant 1.8.3

No, default "true" on Windows and "true" on any other OS.

### Examples

      <delete file="/lib/ant.jar"/>

deletes the file `/lib/ant.jar`.

      <delete dir="lib"/>

deletes the `lib` directory, including all files and subdirectories of `lib`.

      <delete>
        <fileset dir="." includes="**/*.bak"/>
      </delete>

deletes all files with the extension `.bak` from the current directory and any subdirectories.

      <delete includeEmptyDirs="true">
        <fileset dir="build"/>
      </delete>

deletes all files and subdirectories of `build`, including `build` itself.

      <delete includeemptydirs="true">
        <fileset dir="build" includes="**/*"/>
      </delete>

deletes all files and subdirectories of `build`, without `build` itself.

      <delete includeemptydirs="true">
        <fileset dir="src" includes="**/.svn/" defaultexcludes="false"/>
      </delete>

deletes the subversion metadata directories under `src`. Because `.svn` is on of the default excludes you have to use the `defaultexcludes` flag, otherwise Ant wont delete these directories and the files in it.
