ExecOn issue

["Nesbitt, David" <DN...@gensys.com>]

Greetings,

I too have a build process that requires building many standalone
projects.  Prior to trying the optional foreach task, I am trying to get
the build to work using execon.  Essentially, I am trying to cascade the
target to build.xml in the next level subdirectory.  However, I get an
IOException in CreateProcess.

Here is a snippet from the top level build file:

  <target name="abc" >
    <execon executable="ant" >
      <arg value="-buildfile"/>
      <srcfile/>
      <arg value="abc"/>
      <fileset dir=".">
        <patternset>
          <include name="*/build.xml"/>
        </patternset>
      </fileset>
    </execon>
  </target>


Here is the error message:

D:\projects>ant abc -verbose
Ant version 1.3 compiled on June 8 2001

Thanks in advance for any suggestions!

See if executing "cmd.exe /C ant.bat" works.

I'm not a Windows expert (not even a user), but vaguely remember that
you cannot invoke ant.bat by the name ant directly (or any other batch
file for that matter).  IIRC you'd have to use ant.bat (or do you even
have to invoke CMD? - memory failing sorry).
