Here is an example, I havent tested it though
<scriptdef name="hastarget" language="javascript">
<attribute name="targetname" />
<attribute name="property" />
<![CDATA[
var targetname = attributes.get("property");
if(project.getTargets().containsKey(targetname)) {
project.setProperty(attributes.get("property"), "true");
}
]]>
</scriptdef>
the scriptdef can be then invoked as folows
<hastarget targetname="mytarget" property="targetExists"/>
the property 'targetExists' will be set to true if the target 'mytarget' is
present in the project. Otherwise it will not be set.

Hi Vimil,
Thanks for the feedback. Any specifics on just how to do what you
mention (even if untested)?
Thanks again,

I think you can use the scriptdef task to do this. You can write a
script within the scriptdef object to access the methods of the project object.
The project object has methods to list the targets defined under the project,
which you can use to test if a given target exists.
Btw antcall does not launch a new jvm, it only reloads the build.xml.

Subject: Checking if a Target Exists Hi all, I want to be able to check if a
target exists and hope you can help. I'm looking for a generic solution that
doesn't rely any knowledge of the target name to be checked. It is not
possible to modify the target code. And, I'd like to avoid any solutions that
cause the entire JVM to be loaded (e.g., as with antcall). My environment is
Ant 1.7 and allows for the use of Ant-Contrib and Groovy. Any ideas on how to
do this? Even better, any solutions anyone have to share?! Thanks,
