Subject ExecOn issue
Date Tue, 12 Jun 2001 00:54:00 GMT
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
