ant 1.8.0 exec issue

[Phil Bromley <Ph...@cdl.co.uk>]

Hi All,
 
I've found the issue below with 1.8.0 that worked in 1.8.0RC1. This
seems to have been fixed in the latest build - 1.8.1alpha compiled on
April 15 2010 built locally, so I'm not reporting in on bugzilla,
however what is the process for rolling out bug fixes - I'm reluctant to
use the latest build in case other issues arise with this build.
 
Ideally some sort of branched version with this bug fix in would be best
but can you advise what's the best course of action?
 
Details of the os are below. This only seems to be on Windows XP
machines.
 
 
Using ant 1.8.0 - create a target that uses the exec task that calls cmd
then passes command line parameters "/c ant -f test.xml test-output"
which will call an ant target on another build file.
 
ant reports a build failure because the target (the target from the
first build file) does not exist in the build file - which it doesn't
have to - but seems like its ignoring the command line parameters of
which target to run.
 
here are the examples
 
*****file1 - testingoutput.xml *****
 
<project name="testingoutput">
<target name="test-output-file1">
    
        <echo message="here1" />
 
        <exec executable="cmd"
                dir="."
                failonerror="false"
                output="./test.output"
                append="true"
                resultproperty="build.result">
                <arg value="/c"/>
                <arg value="ant -f test.xml test-output"/>
        </exec>
        
        <echo message="here2" />
    
    </target>
</project>
 
*****file2 - test.xml *****
 
<project name="testing-output">
 
<target name="test-output">
            
    <echo message="hello testing"/>
 
</target>
 
</project>
 

****here is the output of running "ant -v -f testingoutput.xml
test-output-file1"*****

In your situation I'd use Ant 1.8.0 and the .bat file from svn until Ant
1.8.1 gets released.
