<title>If and Unless on all tasks/nested elements</title>
</head>

<body>
<h1><a name="if_and_unless">If And Unless</a></h1>

<p>Since Ant 1.9.1 it is possible to add if and unless attributes on all tasks and nested elements using special namespaces.</p>

<p>In order to use this feature you need to add the following namespace declarations</p>
<blockquote><pre>
xmlns:if=&quot;ant:if&quot;
xmlns:unless=&quot;ant:unless&quot;
</pre>
</blockquote>

<p>The if and unless namespaces support the following 3 conditions :
<ul>
<li>true</li>true if the value of the property evaluates to true
<li>blank</li>true if the value of the property is null or empty
<li>set</li>true if the property is set
</ul></p>

<blockquote>
<pre>
&lt;project name=&quot;tryit&quot;
xmlns:if=&quot;ant:if&quot;
xmlns:unless=&quot;ant:unless&quot;
&gt;
&lt;exec executable=&quot;java&quot;&gt;
&lt;arg line=&quot;-X&quot; if:true=&quot;showextendedparams&quot;/&gt;
&lt;arg line=&quot;-version&quot; unless:true=&quot;showextendedparams&quot;/&gt;
&lt;/exec&gt;
&lt;condition property=&quot;onmac&quot;&gt;
&lt;os family=&quot;mac&quot;/&gt;
&lt;/condition&gt;
&lt;echo if:set=&quot;onmac&quot;&gt;running on MacOS&lt;/echo&gt;
&lt;echo unless:set=&quot;onmac&quot;&gt;not running on MacOS&lt;/echo&gt;
&lt;/project&gt;
