Hi everybody,

Seems like I'm running into an unexplainable brick wall that maybe someone
out here as seen before... I've been hitting my head against this for the
past two hours :(
Basically, I'm running antv1.5.1 on JDK 1.3 (ugh, I know), and am having a
problem with the exec task.
When I run the target from the build script that it exists in, I have no
problem whatsoever. My problem is when I try to roll this up into the parent
level build script I get an error.

Error I get:
BUILD FAILED
file:M:/dmctavish_main/sw-profserv/scripts/bundle.xml:110: Execute failed:
java.
io.IOException: CreateProcess: ..\..\sw-tools\nsis\makensis.exe /V1 golden
error=2


Basically, I have a parent level build.xml file with a target
"bundle.golden". This target calls the "bundle" target in the build.xml file
that is found in the golden directory. Nothing special going on in my
mind... here's the parent-level target:

    <target name="bundle.golden">
        <ant dir="golden" target="bundle" inheritall="false"/>
    </target>

In my golden directory, I have a build.xml with the following target:

    <property name="bin.nsis" value="../../tools/nsis/makensis.exe"/>
    <property name="deploy.product.dir" value="../products/golden"/>

    <target name="bundle">
        <exec executable="${bin.nsis}" dir="${deploy.product.dir}">
            <arg line="/V1 golden" />
        </exec>
    </target>

I've surrounded the exec task with <available> tasks to guarantee that the
executable is found, as well as the deploy.product.dir is correct. These
return true whether I call this "bundle" target from the local folder or the
parent.
ie:
<available property="test" file="${bin.nsis}"/>
<available property="test2" file="${deploy.product.dir}/golden.nsi"/>
<echo message="${test}${test2}"/>

debug message reveals the following:
--- Nested Exception ---
java.io.IOException: CreateProcess: ..\..\sw-tools\nsis\makensis.exe /V1

any ideas would be greatly appreciated!
