Creates a zipfile.
The basedir attribute is the reference directory from where to zip.
Note that file permissions will not be stored in the resulting zipfile.
It is possible to refine the set of files that are being zipped. This can be done with the includes, includesfile, excludes, excludesfile and defaultexcludes attributes. With the includes or includesfile attribute you specify the files you want to have included by using patterns. The exclude or excludesfile attribute is used to specify the files you want to have excluded. This is also done with patterns. And finally with the defaultexcludes attribute, you can specify whether you want to use default exclusions or not. See the section on directory based tasks, on how the inclusion/exclusion of files works, and how to write patterns.
This task forms an implicit FileSet and supports all attributes of <fileset>
(dir
becomes basedir
) as well as the nested
<include>
, <exclude>
and <patternset>
elements.
Or, you may place within it nested file sets, or references to file sets. In
this case basedir
is optional; the implicit file set is only
used if basedir
is set. You may use any mixture of the implicit
file set (with basedir
set, and optional attributes like
includes
and optional subelements like <include>
); explicit
nested <fileset>
elements so long as at least one fileset total is
specified. The ZIP file will only reflect the relative paths of files within
each fileset. The Zip task and its derivatives know a special form of a fileset
named zipfileset that has additional attributes (described below).
The Zip task also supports the merging of multiple zip files into the zip file. This is possible through either the src attribute of any nested filesets or by using the special nested fileset zipgroupfileset.
The update
parameter controls what happens if the ZIP file
already exists. When set to yes
, the ZIP file is updated with the
files specified. (New files are added; old files are replaced with the new
versions.) When set to no
(the default) the ZIP file is overwritten
if any of the files that would be added to the archive are newer than the
entries inside the archive. Please note that ZIP files store file modification
times with a granularity of two seconds. If a file is less than two seconds
newer than the entry in the archive, Ant will not consider it newer.
The whenempty
parameter controls what happens when no files
match. If skip
(the default), the ZIP is not created and a warning
is issued. If fail
, the ZIP is not created and the build is halted
with an error. If create
, an empty ZIP file (explicitly zero
entries) is created, which should be recognized as such by compliant ZIP
manipulation tools.
This task will now use the platform's default character encoding for filenames - this is consistent with the command line ZIP tools, but causes problems if you try to open them from within Java and your filenames contain non US-ASCII characters. Use the encoding attribute and set it to UTF8 to create zip files that can safely be read by Java.
Starting with Ant 1.5.2, <zip> can store Unix permissions inside the archive (see description of the filemode and dirmode attributes for <zipfileset>). Unfortunately there is no portable way to store these permissions. Ant uses the algorithm used by Info-Zip's implementation of the zip and unzip commands - these are the default versions of zip and unzip for many Unix and Unix-like systems.
Attribute | Description | Required |
destfile | the zip-file to create. | Exactly one of the two. |
zipfile | the deprecated old name of destfile. | |
basedir | the directory from which to zip the files. | No |
compress | Not only store data but also compress them, defaults to true. Unless you set the keepcompression attribute to false, this will apply to the entire archive, not only the files you've added while updating. | No |
keepcompression | For entries coming from existing archives (like nested zipfilesets or while updating the archive), keep the compression as it has been originally instead of using the compress attribute. Defaults false. Since Ant 1.6 | No |
encoding | The character encoding to use for filenames inside the zip file. Defaults to the platform's default character encoding. | No |
filesonly | Store only file entries, defaults to false | No |
includes | comma- or space-separated list of patterns of files that must be included. All files are included when omitted. | No |
includesfile | the name of a file. Each line of this file is taken to be an include pattern | No |
excludes | comma- or space-separated list of patterns of files that must be excluded. No files (except default excludes) are excluded when omitted. | No |
excludesfile | the name of a file. Each line of this file is taken to be an exclude pattern | No |
defaultexcludes | indicates whether default excludes should be used or not ("yes"/"no"). Default excludes are used when omitted. | No |
update | indicates whether to update or overwrite the destination file if it already exists. Default is "false". | No |
whenempty | behavior when no files match. Valid values are "fail", "skip", and "create". Default is "skip". | No |
duplicate | behavior when a duplicate file is found. Valid values are "add", "preserve", and "fail". The default value is "add". | No |
roundup | Whether the file modification times will be rounded up to
the next even number of seconds. Zip archives store file modification times with a granularity of two seconds, so the times will either be rounded up or down. If you round down, the archive will always seem out-of-date when you rerun the task, so the default is to round up. Rounding up may lead to a different type of problems like JSPs inside a web archive that seem to be slightly more recent than precompiled pages, rendering precompilation useless. Defaults to true. Since Ant 1.6.2 |
No |
The zip task supports any number of nested <fileset>
elements to
specify the files to be included in the archive.
The zip task supports any number of nested <zipfileset>
elements
to specify the files to be included in the archive.
A <zipgroupfileset>
allows for multiple zip files to be merged
into the archive. Each file found in this fileset is added to the archive the
same way that zipfileset src files are added.
<zip destfile="${dist}/manual.zip" basedir="htdocs/manual" />
zips all files in the htdocs/manual
directory into a file called
manual.zip
in the ${dist}
directory.
<zip destfile="${dist}/manual.zip" basedir="htdocs/manual" update="true" />
zips all files in the htdocs/manual
directory into a file called
manual.zip
in the ${dist}
directory. If
manual.zip
doesn't exist, it is created; otherwise it is updated with the
new/changed files.
<zip destfile="${dist}/manual.zip" basedir="htdocs/manual" excludes="mydocs/**, **/todo.html" />
zips all files in the htdocs/manual
directory. Files in the
directory mydocs
, or files with the name todo.html
are
excluded.
<zip destfile="${dist}/manual.zip" basedir="htdocs/manual" includes="api/**/*.html" excludes="**/todo.html" />
zips all files in the htdocs/manual
directory. Only html files
under the directory api
are zipped, and files with the name
todo.html
are excluded.
<zip destfile="${dist}/manual.zip"> <fileset dir="htdocs/manual"/> <fileset dir="." includes="ChangeLog.txt"/> </zip>
zips all files in the htdocs/manual
directory, and also adds the
file ChangeLog.txt
in the current directory. ChangeLog.txt
will be added to the top of the ZIP file, just as if it had been located at
htdocs/manual/ChangeLog.txt
.
<zip destfile="${dist}/manual.zip"> <zipfileset dir="htdocs/manual" prefix="docs/user-guide"/> <zipfileset dir="." includes="ChangeLog27.txt" fullpath="docs/ChangeLog.txt"/> <zipfileset src="examples.zip" includes="**/*.html" prefix="docs/examples"/> </zip>
zips all files in the htdocs/manual
directory into the
docs/user-guide
directory in the archive, adds the file
ChangeLog27.txt
in the current directory as docs/ChangeLog.txt
,
and includes all the html files in examples.zip
under
docs/examples
. The archive might end up containing the files:
docs/user-guide/html/index.html
docs/ChangeLog.txt
docs/examples/index.html
The code
<zip destfile="${dist}/manual.zip"> <zipfileset dir="htdocs/manual" prefix="docs/user-guide"/> <zipgroupfileset dir="." includes="examples*.zip"/> </zip>
zips all files in the htdocs/manual
directory into the
docs/user-guide
directory in the archive and includes all the files in
any file that maches examples*.zip
, such as all files within
examples1.zip
or examples_for_brian.zip
.
