<h2><a name="icontract">icontract</a></h2>
<h3>Description</h3>

<P>
Instruments Java classes with <a href="http://www.reliable-systems.com/tools/">iContract</a>
 DBC preprocessor.<br>
 The task can generate a properties file for <a href="http://home.sol.no/~hellesoy/icplus.html">iControl</a>,
 a graphical user interface that lets you turn on/off assertions. iControl generates a control file that you can refer to
 from this task using the controlfile attribute.
 </p>

     <td valign="top" align="center">Yes</td>
   </tr>
   <tr>
     <td valign="top">instrumentdir</td>
     <td valign="top">Indicates where the instrumented source files should go.</td>

   <tr>
     <td valign="top">builddir</td>
     <td valign="top">Indicates where the compiled instrumented classes should go.
       Defaults to the value of instrumentdir.
       <em>NOTE:</em> Don't use the same directory for compiled instrumented classes
       and uninstrumented classes. It will break the dependency checking. (Classes will
       not be reinstrumented if you change them).</td>
     <td valign="top" align="center">No</td>
   </tr>
   <tr>
     <td valign="top">repbuilddir</td>
     <td valign="top">Indicates where the compiled repository classes should go.
       Defaults to the value of repositorydir.</td>
     <td valign="top" align="center">No</td>
   </tr>
   <tr>
     <td valign="top">pre</td>
     <td valign="top">Indicates whether or not to instrument for preconditions.
       Defaults to <code>true</code> unless controlfile is specified, in which case it
       defaults to <code>false</code>.</td>
     <td valign="top" align="center">No</td>
   </tr>
   <tr>
     <td valign="top">post</td>

   </tr>
   <tr>
     <td valign="top">invariant</td>
     <td valign="top">Indicates whether or not to instrument for invariants.
       Defaults to <code>true</code> unless controlfile is specified, in which case it
       defaults to <code>false</code>.</td>
     <td valign="top" align="center">No</td>
   </tr>
   <tr>
     <td valign="top">failthrowable</td>
     <td valign="top">The full name of the Throwable (Exception) that should be
       thrown when an assertion is violated. Defaults to <code>java.lang.Error</code></td>
     <td valign="top" align="center">No</td>
   </tr>
   <tr>
     <td valign="top">verbosity</td>
     <td valign="top">Indicates the verbosity level of iContract. Any combination
       of <code>error*,warning*,note*,info*,progress*,debug*</code> (comma separated) can be

     <td valign="top" align="center">No</td>
   </tr>
   <tr>
     <td valign="top">quiet</td>
     <td valign="top">Indicates if iContract should be quiet. Turn it off if many your classes extend uninstrumented classes
     and you don't want warnings about this. Defaults to <code>false</code></td>

   </tr>
   <tr>
     <td valign="top">updateicontrol</td>
     <td valign="top">If set to true, it indicates that the properties file for
       iControl in the current directory should be updated (or created if it doesn't exist).
       Defaults to <code>false</code>.</td>
     <td valign="top" align="center">No</td>
   </tr>
   <tr>
     <td valign="top">controlfile</td>
     <td valign="top">The name of the control file to pass to iContract. Consider using iControl to generate the file.
       Default is not to pass a file. </td>
     <td valign="top" align="center">Only if <code>updateicontrol=true</code></td>
   </tr>
   <tr>
     <td valign="top">classdir</td>
     <td valign="top">Indicates where compiled (unistrumented) classes are located.
       This is required in order to properly update the icontrol.properties file, not
       for instrumentation.</td>
     <td valign="top" align="center">Only if <code>updateicontrol=true</code></td>
   </tr>
   <tr>
     <td valign="top">targets</td>
     <td valign="top">Name of the file that will be generated by this task, which lists all the
        classes that iContract will instrument. If specified, the file will not be deleted after execution.
        If not specified, a file will still be created, but it will be deleted after execution.</td>
     <td valign="top" align="center">No</td>
