BUILD FAILED 
file:C:/Ant/bin/build.xml:34: no source files and no packages have been specified. 

Build file contains; 
 <property name="ProjectHome" value="c:/learn/Ex1" /> 
  <property name="src" value="${ProjectHome}/src" />

  <property name="dist" value="${ProjectHome}/lib" />

- <target name="docs" depends="compile">
  <mkdir dir="${docs}" /> 
  <javadoc packagenames="Exercise1" sourcepath="${src}" destdir="${docs}" /> 
  </target>

Ant -version runs ok from c:/Ant/bin

Scratching my head why it cant find the source and packages? 
Ant 1.5.4
JDK j2sdk1.4.1_06

thanks in anticipation.
