javac problem with include, includes and includefile

[Marco Cardani (mcardani)]

Hi all,
the javac task is skipped when I run the following examples:
 
<javac srcdir="my_src" destdir="my_dest" includes="pippo.java">
     <classpath refid="my_ref"/>
</javac>
 
<javac srcdir="my_src" destdir="my_dest">
     <include name="pippo.java"/>
     <classpath refid="my_ref"/>
</javac>
 
<javac srcdir="my_src" destdir="my_dest" includefile="src.txt">
     <classpath refid="my_ref"/>
</javac>
 
if I use the no one of the above statements the javac will be executed
including all the .java files.
  
<javac srcdir="my_src" destdir="my_dest">
     <classpath refid="my_ref"/>
</javac>
 
Any help will be appreciate.
TIA
marco.
