(1) Make sure there is a Copyright notice on all visible files. (2) Make sure all years in which the file has been modified are listed. (3) Make sure the format is consistent, i.e. separate consecutive years with a dash, not a comma. When Stephane changed starteam.html it has been 2001 in France but 2002 in Australia - does that mean we add 2002 to the Copyright line or not? ;-) git-svn-id: https://svn.apache.org/repos/asf/ant/core/trunk@270652 13f79535-47bb-0310-9956-ffa450edef68

<h2>DependSet</h2>
|
|
|
|
A task to manage arbitrary dependencies between files.
|
|
|
|
<h3>Description</h3>
|
|
|
|
<p>
|
|
The dependset task compares a set of source files with a set of target
|
|
files. If any of the source files is more recent than any of
|
|
the target files, all of the target files are removed.
|
|
</p>
|
|
<p>
|
|
Source files and target files are specified via nested <a
|
|
href="../CoreTypes/fileset.html">FileSets</a> and/or nested <a
|
|
href="../CoreTypes/filelist.html">FileLists</a>. Arbitrarily many
|
|
source and target filesets/filelists may be specified, but at
|
|
least one filelist/fileset is required for both sources and targets.
|
|
</p>
|
|
<p>
|
|
Use a FileSet when you want to use wildcard include or exclude
|
|
patterns and don't care about missing files. Use a FileList when you
|
|
want to consider the non-existence of a file as if it were out of
|
|
date. If there are any non-existing files in any source or target
|
|
FileList, all target files will be removed.
|
|
</p>
|
|
<p>
|
|
DependSet is useful to capture dependencies that are not or cannot be
|
|
determined algorithmically. For example, the <style> task only
|
|
compares the source XML file and XSLT stylesheet against the target
|
|
file to determined whether to restyle the source. Using dependset you
|
|
can extend this dependency checking to include a DTD or XSD file as
|
|
well as other stylesheets imported by the main stylesheet.

<h3>Parameters</h3>
|
|
|
|
<p>
|
|
(none)
|
|
</p>
|
|
|
|
<h3>Parameters Specified as Nested Elements</h3>
|
|
|
|
<h4>srcfileset</h4>
|
|
|
|
<p>
|
|
The nested <code>srcfileset</code> element specifies a <a
|
|
href="../CoreTypes/fileset.html">FileSet</a>. All files included in
|
|
this fileset will be compared against all files included in all of the
|
|
<code>targetfileset</code> filesets and <code>targetfilelist</code>
|
|
filelists. Multiple <code>srcfileset</code> filesets may be specified.
|
|
</p>
|
|
|
|
<h4>srcfilelist</h4>
|
|
|
|
<p>
|
|
The nested <code>srcfilelist</code> element specifies a <a
|
|
href="../CoreTypes/filelist.html">FileList</a>. All files included in
|
|
this filelist will be compared against all files included in all of the
|
|
<code>targetfileset</code> filesets and <code>targetfilelist</code>
|
|
filelists. Multiple <code>srcfilelist</code> filelists may be specified.
|
|
</p>
|
|
|
|
<h4>targetfileset</h4>
|
|
|
|
<p>
|
|
The nested <code>targetfileset</code> element specifies a <a
|
|
href="../CoreTypes/fileset.html">FileSet</a>. All files included in
|
|
this fileset will be compared against all files included in all of the
|
|
<code>srcfileset</code> filesets and <code>sourcefilelist</code>
|
|
filelists, and if any are older, they are all deleted.
|
|
</p>
|
|
|
|
<h4>targetfilelist</h4>
|
|
|
|
<p>
|
|
The nested <code>targetfilelist</code> element specifies a <a
|
|
href="../CoreTypes/filelist.html">FileList</a>. All files included in
|
|
this filelist will be compared against all files included in all of the
|
|
<code>srcfileset</code> filesets and <code>sourcefilelist</code>
|
|
filelists, and if any are older, they are all deleted.
|
|
</p>
|
|
|
|
<h3>Examples</h3>
|
|
<blockquote> <pre>
|
|
<dependset>
|
|
<srcfilelist
|
|
dir = "${dtd.dir}"
|
|
files = "paper.dtd,common.dtd"/>
|
|
<srcfilelist
|
|
dir = "${xsl.dir}"
|
|
files = "common.xsl"/>
|
|
<srcfilelist
|
|
dir = "${basedir}"
|
|
files = "build.xml"/>
|
|
<targetfileset
|
|
dir = "${output.dir}"
|
|
includes = "**/*.html"/>
|
|
</dependset> </pre>
|
|
</blockquote>
|
|
|
|
<p>
|
|
In this example derived HTML files in the ${output.dir} directory
|
|
will be removed if any are out-of-date with respect to:</p>
|
|
<ol>
|
|
<li>the DTD of their source XML files</li>
|
|
<li>a common DTD (imported by the main DTD)</li>
|
|
<li>a subordinate XSLT stylesheet (imported by the main stylesheet), or</li>
|
|
<li>the buildfile</li>
|
|
</ol>
|
|
|
|
<p>
|
|
If any of the source files in the above example does not exist, all
|
|
target files will also be removed. To ignore missing source files instead,
|
|
use filesets instead of filelists for the source files.
