Most Eclipse™ distributions include a plugin to launch Apache Ant build files. The provided Apache Ant distribution is a standard distribution of Ant that doesn't include Apache Ivy. You may wish to run Ivy targets against Eclipse's Ant distribution.

<h1>Install the plugin</h1>

Since IvyDE 2.2, a dedicated plugin can be install so that Ivy Ant tasks are automatically added to Ant's classpath. Go check the IvyDE updatesite and install the plugin named "Apache Ivy Ant Tasks"

<h1>Manual Configuration</h1>

If you want to install your custom version of Ivy, you'll need to do it manually.

In the global preference page of the Ant runtime, click on <b>Add External JARs...</b>

Then browse your filesystem to the <tt>plugins</tt> directory of your Eclipse installation and select the Ivy jar named <tt>org.apache.ivy_2.X.X.XXXXXXXXX.jar</tt>. Now Ivy has been added to the classpath of the Ant distribution embedded in Eclipse.

<h1>Run Apache Ivy targets</h1>

Create an Ant build file and declare the Ivy targets with:
<code>
    <taskdef resource="org/apache/ivy/ant/antlib.xml" uri="antlib:org.apache.ivy.ant" />
</code>
And don't forgot to declare the namespace <tt>xmlns:ivy="antlib:org.apache.ivy.ant"</tt>.

After the taskdefs have been added, you will have code completion on Ivy tasks:

The build will now be successful:
