Hi,
Yes, it would be better to patch uptodate, however it may be
difficult to do that as the assumptions (one target file -> multiple file=
s)
have changed. Also, the task/condition uses a fileset for sourcefiles,
which meant that for multiple source files, the task would succeed
if some of the source files were missing.

Also, I wanted to reverse the logic as the targets being outofdate
would cause actions more often than them not been outofdate.

Initialially my build scripts where using constructions like:

<if>
   <and>
       <uptodate srcfile=3D"xxx"  targetfile=3D"xxx.out"/>
       <uptodate srcfile=3D"yyy" targetfile=3D"yy.out"/>
     </and>
    <else>
    </else>
</if>

which was a bit offputting...

Using my custom extension patch (ant bugzilla 17199) one
can use outofdate with if as follows:

 <typedef name=3D"outofdate"=20
               classname=3D"net.sf.antcontrib.logic.OutOfDate"/>

<if>
    <outofdate>
         <sourcefiles>
              <filelist dir=3D"." files=3D"xxx,yyy"/>
          </sourcefile>
         <targetfiles>
              <filelist dir=3D"." files=3D"xxx.out,yyy.out"/>
          </targetfile>
     </outofdate>
    <then>
    </then>
</if>

Which is a bit verbose :-)  but easy to understand.

Would it be better to use the "dependset" sub elements=20
(srcfileset, srcfilelist, targetfilelist, targetfileset) instead (from=20

<if>
    <outofdate>
        <srcfilelist dir=3D"." files=3D"xxx,yyy"/>
        <targetfilellist dir=3D"." files=3D"xxx.out,yyy.out"/>
     </outofdate>
     <then>
      </then>
</if>
