: where is preamble to bin/antRun set?
So I am able to get <exec> to work with the original antRun file supplied
with my ant install (I am running in Linux), but there is something very
strange going on. If my <project> base directory is called /foo then I
*must* have the file antRun located at /foo/bin/antRun otherwise I get the
following error message:
"Execute failed: java.io.IOException: /foo/bin/antRun: not found"
This is slightly annoying since I didn't even have a /foo/bin folder in my
project to begin with. Surprisingly, with ANT_HOME set to /opt/ant, even if
I move antRun from ANT_HOME/lib (where it was originally located) straight
into ANT_HOME, the ant build still cannot find the file antRun.
I think the key question here is: Where is the preamble to bin/antRun set.
Anyone know the answer to this one? Thanks!

As you might know, Java cannot access environment variables. That's
why the script intended to start Ant (bin/ant not build.sh) translates
ANT_HOME into the property ant.home.
I don't know why you've written your own wrapper instead of using ant
(build.sh is only intended to build Ant, not to use Ant), change the
invocation to read -Dant.home="$ANT_HOME" instead and you should be
done.
You can use ~/.antrc with a line like
ANT_OPTS='-classpath "$TEMP_CP"'
or similar to set additional arguments to Ant on a permanent basis
(if you use ANT_HOME/bin/ant that is).

David,
You may be better off using the ant script rather than munging build.sh. The
problem appears to be
-Dant.home=.
Since Java does not read the values of environment variables, the value of
$ANT_HOME is passed to ant by defining the property ant.home. Your script is
setting this to "." and not "/opt/ant". Try changing your script to
-Dant.home=$ANT_HOME
or use the ant script in $ANT_HOME/bin

Re: : where is preamble to bin/antRun set?

$ANT_HOME is set correctly, to /opt/ant. The build.sh file I am using to run
ant on my project launches ant using the line:
"$JAVA_HOME"/bin/java -Dant.home=. -classpath "$TEMP_CP"
org.apache.tools.ant.Main $@
to run ant, but this copy of build.sh does not override ANT_HOME. TEMP_CP is
my CLASSPATH, slightly modified for running ant...
Thanks for your help!

This is extremely strange. Ant will search for and execute
$ANT_HOME/bin/antRun (and does so on my Linux box BTW).
To get the behavior you are experiencing, something must be setting
either ANT_HOME or the Ant property ant.home to your project's
basedir. I know Ant's own build.sh overrides the ANT_HOME setting and
sets it to ".", you're not accidently invoking this one, are you? The
script named ant is the one that should be used.
