<h2><a name="intro">Introduction</a></h2>
<p>These tasks provide an interface to the <a href="http://www.perforce.com" target="_top">Perforce</a> SCM.
The <code>org.apache.tools.ant.taskdefs.optional.perforce</code> package consists of a simple framework to support 
p4 functionality as well as some Ant tasks encapsulating frequently used (by me :-) p4 commands. 
However, the addition of new p4 commands is a pretty simple task (see the source). 
Although it is possible to use these commands on the desktop, 
they were primarily intended to be used by automated build systems.</p>

<p><b>Note:</b> These tasks require the <a href="http://jakarta.apache.org/oro" target="_top">oro 2.0.XXX</a> regular
expression package. Simply download this package and copy the jakarta-oro-2.0.XXX.jar file into Ant's lib directory.
You will also need the Perforce client executable (p4 or p4.exe but not p4win.exe) in your path.
</p>

<h3>General P4 Properties</h3>
<p>Each p4 task requires a number of settings, either through build-wide properties, individual attributes 
or environment variables. These are
</p>
<table border="1" cellpadding="2" cellspacing="0">
  <tr>
    <td valign="top"><b>Property</b></td>
    <td valign="top"><b>Attribute</b></td>
    <td valign="top"><b>Env Var</b></td>
    <td valign="top"><b>Description</b></td>
    <td align="center" valign="top"><b>Default</b></td>
  </tr>
  <tr>
    <td valign="top">p4.port</td>
    <td valign="top">port</td>
    <td valign="top">P4PORT</td>
    <td valign="top">The p4d server and port to connect to</td>
    <td valign="top">perforce:1666</td>

    <td valign="top">view</td>
    <td valign="top" align="center">--</td>
    <td valign="top">The client, branch or label view to operate upon. See the p4 user guide for more info.</td>
    <td valign="top">//...</td>
  </tr>

</table>
<p>
Your local installation of Perforce may require other settings (e.g. P4PASSWD, P4CONFIG). At the moment, these can only be set outside of Ant, as environment variables.
</p>
<p>
Additionally, you may also specify the following attributes:
</p>
<p>
<table border="1" cellpadding="2" cellspacing="0">
<tr>
  <td valign="top"><b>Attribute</b></td>
  <td valign="top"><b>Description</b></td>
  <td align="center" valign="top"><b>Required</b></td>
</tr>
<tr>
    <td valign="top">failonerror</td>
    <td valign="top">Specifies whether to stop the build
     (<code>true</code>|<code>yes</code>|<code>on</code>)
     or keep going (<code>false</code>|<code>no</code>|<code>off</code>)
     if an error is returned from the p4 command.</td>
    <td valign="top">No; defaults to true.</td>
  </tr>
</table>
</p>

<h3>Examples</h3>
<p>Setting in the environment:-</p>
<p>
(Unix csh)</p>
<pre>setenv P4PORT myperforcebox:1666</pre>
<p>(Unix sh et al)</p>
<pre>P4USER=myp4userid; export P4USER</pre>
<p>Using build properties:-</p>
<pre>&lt;property name=&quot;p4.client&quot; value=&quot;nightlybuild&quot;/&gt;</pre>
<p>Using task attributes:-</p>
<pre>
&lt;p4Whatever
	port=&quot;myserver:1666&quot;
	client=&quot;smoketest&quot;
	user=&quot;smoketestdude&quot;
	.
	.
	.
