Subject Re: Attributes for several tasks all at once?
Date Wed, 11 Jul 2001 15:59:48 GMT
I came up with a pattern that uses one target to do the compile and
then other targets use antcall to invoke it, like this:

  <!-- ==================================================================== -->
  <!-- Generic compilation target - uses javac.patternset to control        -->
  <!-- what gets compiled                                                   -->
  <!-- ==================================================================== -->
  <target name="generic-compile">
    <javac srcdir="${src.dir}"
           destdir="${build.lib}"
           debug="${debug}"
           deprecation="${deprecation}"
           optimize="${optimize}"
           failonerror="yes"
           depend="yes"
           includeAntRuntime="no" >
      <bootclasspath refid="rt.path" />
      <classpath refid="base.path" />
      <patternset refid="${javac.patternset}" />
    </javac>
  </target>
  
  <!-- ==================================================================== -->
  <!-- Compile everything at once                                           -->
  <!-- ==================================================================== -->
  <target name="compile"
          depends="prepare-build"
          description="Compile ALL classes at once" >

    <antcall target="generic-compile">
      <param name="javac.patternset" value="le.paths.all"/>
    </antcall>
  </target>
  
  <!-- ==================================================================== -->
  <!-- Compile the utility classes                                          -->
  <!-- ==================================================================== -->
  <target name="compile-util"
          depends="prepare-build"
          description="Compile the utility classes" >

    <antcall target="generic-compile">
      <param name="javac.patternset" value="le.paths.util"/>
    </antcall>
  </target>
