Support for providing own templates visible in New File... action.

What is New (see all changes)?

Use Cases

The main use case is for project type providers to supply logical views and customizers for the project. Also for template providers to create project-aware file templates. Can also get a list of open projects, create different kinds of project-related actions, and select projects on disk.

The Project UI API provides some miscellaneous APIs and SPIs relating to the appearance and UI behavior of generic projects. Most importantly, it permits the customizer and logical view of a project to be defined.


Callbacks intended to let the Project UI module plug in implementations of APIs defined here. Uses implementation dependencies.

Group of property interfaces
Interface NameIn/OutStabilitySpecified in What Document?

Since version 1.55 a special PropertyChangeEvent is generated for benefit of ide.ergonomics module by OpenProjects.getDefault(). The property name of the event is "willOpenProjects" and its new value contains an array of projects that will be opened (a type Project[]). Ergonomics module uses this information to enable modules that seem to provide support for technologies used in the about to be opened projects.


project.license attribute contains project license as String for newly created templates. It is used to import license templates. The default is used if the attribute was not found in any project lookup.


project.encoding attribute contains the project encoding as String for newly created templates. The encoding of the parent folder of the new file is used if the attribute was not found in any project lookup.


contains String path to the license header include file, by default as path to Templates/Licenses/license-${project.license}.txt system filesystem location, but a local filesystem (file:) url is also supported.

Group of lookup interfaces
Interface NameIn/OutStabilitySpecified in What Document?

The attributes provider is registered in META-INF/services. It collects attributes from org.openide.loaders.CreateFromTemplateAttributesProviders registered in project lookups. It provides the project.license and project.encoding attributes for file templates using scripting support.

Group of layer interfaces
Interface NameIn/OutStabilitySpecified in What Document?
RegisteredActionsExportedUnder Development

Several project related actions are registered in the Actions folder in the layer. Product branding is intended to use those actions to build main menu, toolbars and shortcuts.

  • Actions/Project/org-netbeans-modules-project-ui-BuildMainProject.instance
  • Actions/Project/org-netbeans-modules-project-ui-CleanMainProject.instance
  • Actions/Project/org-netbeans-modules-project-ui-RebuildMainProject.instance
  • Actions/Project/org-netbeans-modules-project-ui-RunMainProject.instance
  • Actions/Project/org-netbeans-modules-project-ui-DebugMainProject.instance
  • Actions/Project/org-netbeans-modules-project-ui-TestProject.instance
  • Actions/Project/org-netbeans-modules-project-ui-BuildProject.instance
  • Actions/Project/org-netbeans-modules-project-ui-CleanProject.instance
  • Actions/Project/org-netbeans-modules-project-ui-RebuildProject.instance
  • Actions/Project/org-netbeans-modules-project-ui-RunProject.instance


New (or import) project wizards can be registered in a special folder Templates/Projects/.


Providers of generic project actions can register Action and JSeparator instances in a special folder Projects/Actions/. So if any module wishes to extend, hide or reorder some of them it can just register its actions there. Example:

    <folder name="Projects" >
        <folder name="Actions" >
            <file name="org-mymodule-MyAction.instance" >
                <attr name="instanceCreate" stringvalue="org.mymodule.MyAction" />


File templates can be registered with various attributes, some specific to the project system.


Under Templates/Licenses folder should be registered various license headers that can be imported by templates using scripting. The recommended format of filename is license-[licensename].txt e.g. license-cddl.txt.

Implementation Details

Where are the sources for the module?

The sources for the module are in the NetBeans Mercurial repositories.

What do other modules need to do to declare a dependency on this one, in addition to or instead of a plain module dependency?
