Alternatively, you can set <code>inheritall</code> to <b>false</b> to not copy any properties to the new project. </p> <p> You can also set properties in the new project from the old project by using nested property tags. These properties are always passed to the new project regardless of the setting of <code>inheritall</code>. This allows you to parameterize your subprojects. </p> <p> References to data types can also be passed to the new project, but by default they are not. If you set the <code>inheritrefs</code> to <b>true</b>, all references will be copied. </p> <h3>Parameters</h3> <div class="table"> <table> <tr> <th>Attribute</th> <th style="text-align: center;">Type</th> <th>Description</th> <th style="text-align: center;">Required</th> </tr> <tr> <td valign="top">buildfile</td> <td style="text-align: center;">file</td> <td> The build file to build. </td> <td style="text-align: center;">False</td> </tr> <tr> <td valign="top">inheritall</td> <td style="text-align: center;">bool</td> <td> Specifies whether current property values should be inherited by the executed project.
