## Export ant task |

| The export ant task can be used to export views from a saved snapshot. For more information please consult the overview.

| You can integrate the command line export with your ant script (read about ant at ant.apache.org) by using the `export` task that is provided in `{JProfiler installation directory}/bin/ant.jar`. To make the `export` task available to ant, you must first insert a `taskdef` element that tells ant where to find the task definition. Here is an example of using the task in an ant build file:
          <taskdef name="export"
                   classname="com.jprofiler.ant.ExportTask"
                   classpath="C:\Program Files\jprofiler4\bin\ant.jar"/>

          <target name="export">
            <export snapshotfile="c:\home\ingo\test.jps">
              <view name="CallTree" file="calltree.html"/>
              <view name="HotSpots" file="hotspots.html">
                <option name="expandbacktraces" value="true"/>
                <option name="aggregation" value="class"/>
              </view>
            </export>
          </target>
The `taskdef` definition must occur only once per ant-build file and can appear anywhere on the top level below the `project` element. Note: it is not possible to copy the `ant.jar` archive to the `lib` folder of your ant distribution. You have to reference a full installation of JProfiler in the task definition.
