Ant goodies 1

Suppose you have a library project checked into subversion

library
  |_apache
     |_log4j
         |_ log4j-1.2.15.jar

and you wanted to copy such library jars to your target dir when you kick an ant build

here is what I created!

[code]

            <findAndCopy fromdir="${master.library.dir}" todir="${lib.dir}" filenames="${project.classpath.compile}" />

where project.classpath.compile=log4j-1.2.15.jar,junit-4.7.jar

<macrodef name="findAndCopy">
    <attribute name="fromdir" />
    <attribute name="todir" />
    <attribute name="filenames" />
    <sequential>
          <for list="@{filenames}" param="file">
            <sequential>
              <echo>iterate == '@{file}'</echo>
              <copy todir="@{todir}" flatten="true">
                <fileset dir="@{fromdir}" includes="**/*.jar">
                  <filename name="**/@{file}" />
                </fileset>
              </copy>
            </sequential>
          </for>
    </sequential>
  </macrodef>

[/code]

oh, I do use ant-contrib, that is evil!
