In Eclipse Helios:

• Open the Preferences dialog (Window -> Preferences)
• Navigate to the Ant -> Runtime page
• Expand the Ant Home Entries node on the Classpath tab

This shows the path used for Ant classpath, which also reveals ANT_HOME for Eclipse.

So by default in Helios you will have something like:

<ECLIPSE_ROOT>/plugins/org.apache.ant_1.7.1.v20100518-1145\lib\ant.jar
etc

On this same page, you can also change ANT_HOME to use a different version of Ant you have installed on your PC.

Create a build file and echo $ant.version

On Helios

1. create an empty build.xml
2. ctrl+space in the empty file and select the default build file template with 2 targets
3. in the target called "default" add <echo>${ant.version}</echo>
4. save the file
5. right click on the build.xml in the navigator
6. select run as ant build

In Eclipse Helios (version 3.6.2) the version of the various plug-in modules such as ANT can be determined in the following manner.

Select the Help -> "About Eclipse SDK" menu option
Click on the "Installation Details" button
Click on the "Plug-ins" Tab
The "Plug-in Name" column is where ANT can be found the version is in the next column.

There will probably be multiple references to ANT in the "Plug-in Name" column including

Ant Build Tool Core
Ant Launching support
Ant UI
Apache Ant

I believe the "Apache Ant" is the most relevant entry and the others deal with how ant integrates with eclipse.
