Export ant task

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.
