In the master index project, right-click the Custom Plug-ins folder.
Select Build from the context menu that appears.
If you modify a custom plug-in file after it has been checked in, be sure to check the file out before making any changes; otherwise, any changes will be lost when you try to save the file. Rebuild the plug-in after you save the changes, and then regenerate the application to incorporate the changes. Regenerating the application also rebuilds all custom plug-ins.
