Loops are not our friends :-) (if someone wishes to get them included into ant-core...)   How about:       <script language="_javascript_"> <![CDATA[         var ant = myProject.createTask("ant");         var echo = myProject.createTask("echo");         var fileset = myProject.createDataType("fileset");                 fileset.setDir(new java.io.File("."));         fileset.setIncludes("*/**/build.xml");                 var dirScanner = fileset.getDirectoryScanner(test);         var files = dirScanner.getIncludedFiles();                 for (i = 0; i < files.length; i++)         {             file = new java.io.File(files[i]);             dir = file.getParent();             antfile = file.getName();             ant.setDir(new java.io.File(dir));             ant.setAntfile(antfile);             ant.execute();         }     ]]></script>   Your number 2 could be       <script language="_javascript_"> <![CDATA[             var ant = myProject.createTask("ant");         var echo = myProject.createTask("echo");         var fileset = myProject.createDataType("fileset");                 fileset.setDir(new java.io.File("."));         fileset.setIncludes("*/**/build.xml");                 var dirScanner = fileset.getDirectoryScanner(test);         var files = dirScanner.getIncludedFiles();           if (files != null && files.length != 0) myProject.setProperty('sub.build.exists', 'true');             ]]></script>   The last one can not be solved by <script>, but should be possible using .bat-files. (At least on NT or W2K). Complexity depends on your requirements. If one target and up to 8 variable properties are enough for you and it's not a problem if you end up with properties containing "" (space) you can 1. remove everything between ":start" and ":doneArgs" 2. Change the command-line after ":runAnt" to  %_JAVACMD% -classpath %LOCALCLASSPATH% -Dant.home="%ANT_HOME%" %ANT_OPTS% org.apache.tools.ant.Main %1 -Darg1=%2 -Darg2=%3 -Darg3=%4 -Darg4=%5 -Darg5=%6 -Darg6=%7 -Darg7=%8 -Darg8=%9 3) I modified Main to accept only one task at a time.  All additional arguments are translated into user-properties. (This one is NOT backward compatible) Yeah, I was thinking of going that route, but I'm way better at Java than at .bat or sh scripts.  (Can this even be done on a windows environment??).  Anyway, I agree with your assessment on this last item, but I strongly believe ant needs both a conditional, and a looping task. Has this idea already been shot down?
