How do I copy a directory in Ant without deleting existing files in the destination directory?

I have the following file structure:

I am copying FolderToBeCopied to a location which already contains files:

I copy using the following in my Ant build script:

<copy overwrite="true" todir="DestinationFolder">
            <fileset dir="FolderToBeCopied" includes="**">
            </fileset>
        </copy>

However, when I run the build script, it copies the files somefile1 and somefile2 to folder1 at the destination, but deletes the files already in folder1 (ie. anotherfile1, anotherfile2). Is there a way to prevent it deleting files already in the destination folder?

In order to prevent deletion of existing files in the destination folder, you could make a backup appending a timestamp to the filenames:

<project name="demoSO" basedir=".">

   <tstamp>
    <format property="touch.time" pattern="yyMMddHHmmssSSS"/>
  </tstamp>

  <target name="copyMyFiles">
    <copy todir="DestinationFolder" includeemptydirs="false">
      <fileset dir="FolderToBeCopied">
      </fileset>
      <mapper type="glob" from="*" to="*-${touch.time}"/>
    </copy>
  </target>

</project>

Yes: Locate the delete element in your build script which deletes DestinationFolder and delete it.

copy doesn't delete. overwrite only means "copy even if the target is older than the source".
