I don't think you can use <condition> to check if a property is simply set
(regardless of what it's set to) -- but you could use the if/unless attrs
instead:

  <target name="setCompile" depends="chkInc, chkEx" unless="notAll">
    <property name="compile.all" value="true"/>
  </target>

  <target name="chkInc" if="include.module">
    <property name="notAll" value="true"/>
  </target>
  <target name="chkEx" if="exclude.module">
    <property name="notAll" value="true"/>
  </target>

To use <condition>, you'd need to compare against all the possible module
names -- eg:
    <condition property="compile.all">
      <not>
        <or>
          <equals arg1="${include.module}" arg2="foo"/>
          <equals arg1="${include.module}" arg2="bar"/>
          <equals arg1="${exclude.module}" arg2="foo"/>
          <equals arg1="${exclude.module}" arg2="bar"/>
        </or>
      </not>
    </condition>
which could get real ugly real fast.
