Hello Dewey,
What is the operating system you are using. If it is
windows, error=2 usually means that windows is not
able to find the executable, i.e. it is not in the
classpath. Also bear in mind that the usual way of
using <exec> on windows is like this:
<exec dir="....." executable="cmd.exe"
os="Windows 2000,Windows XP">
<arg line="/c ant -projecthelp"/>
</exec>
and it is described fully in <exec> docs[1].
Since you are invoking it in ant build script, then
${ant.home} is already set, so that you can also
provide the absolute path to ant launching script:
<arg line="/c ${ant.home}/bin/ant -projecthelp"/>
I have done this before and I would recommend you to
use <java> task (written by memories and not tested) :
<java classname="org.apache.tools.ant.Main">
<arg value="-projecthelp"/>
<classpath>
<pathelement
location="${ant.library.dir}/ant.jar"/>
</classpath>
</java>
