Uptodate - need some help...

["Ciramella, EJ" <EC...@emptoris.com>]

could someone give me a little guidance using the uptodate task?  I'm trying
to compare a set of jars against the build directory to see if the classes
are newer than the jars.

I think this is done automagically by the Jar task anyway.
  At least it seems to be for mine :

    <target name="jar" depends="stub">
         <echo message="Checking jar for ${ant.project.name} 
(${jar.file})" />
	<jar jarfile="${jar.file}" update="yes">
          <fileset dir="${classes.dir}" />
          <fileset dir="${metadata.dir}" >
            <include name="**/*.properties"/>
            <include name="**/*.css"/>
          </fileset>
          <zipfileset dir="${image.dir}" prefix="images"/>
          <manifest>
            <attribute name="Built-By" value="${user.name}"/>
            <attribute name="Main-class" 
value="${package.name}.${main.class}"/>
            <attribute name="Class-path" value="lib/GuibioMiRe.jar 
lib/linguisticServices.jar lib/jaxb-api.jar lib/jaxb-ri.jar 
lib/jaxb-libs.jar lib/jaxb-xjc.jar lib/log4j-1.2.5.jar lib/jgraph.jar 
lib/jlfgr-1_0.jar lib/dom4j.jar "/>
          </manifest>
         </jar>
</target>

However, you may want to have something conditional on the JAR actually 
changing, like perhaps deploying it somewhere or sending an e-mail if 
it has changed.  So use this as an example of how <uptodate> works, not 
necessarily as a way to bypass using <jar>.  :))

From the "book" Java Dev with ant:

<uptodate property="jar.uptodate">
    <srcfiles dir="classes" includes="**/*.class"/>
    <mapper type="merge" to="${dist.dir}/product.jar"/>
</uptodate>

However, the jar task does this already...
