It will then increment the number by one and write it back out to the file. (See the <a href="../Tasks/propertyfile.html">PropertyFile</a> task if you need finer control over things such as the property name or the number format.)</p> <h3>Parameters</h3> <table class="attr"> <tr> <th scope="col">Attribute</th> <th scope="col">Description</th> <th scope="col">Required</th> </tr> <tr> <td>file</td> <td>The file to read and write the build number from/to.</td> <td>No; defaults to <q>build.number</q></td> </tr> </table> <h3>Examples</h3> <p>Read, increment, and write a build number to the default file, <samp>build.number</samp>.</p> <pre><buildnumber/></pre> <p>Read, increment, and write a build number to the file <samp>mybuild.number</samp>.</p> <pre><buildnumber file="mybuild.number"/></pre> </body> </html>
