Unable to set hierarchical project presentation by default [message #1787602] Tue, 29 May 2018 21:19 Go to next message

I'm trying to get Project Explorer > Projects Presentation > Hierarchical set by default (as opposed to Flat) in a custom Eclipse RCP application.

We've had great luck using plugin_customization.ini for most preferences, but org.eclipse.ui.navigator.ProjectExplorer.activatedExtensions and org.eclipse.ui.navigator.ProjectExplorer.filterActivation have been causing grief.

- I start our product with new / clean workspace, exit, then create a copy of the whole .metadata structure.


- I start our product, set Projects Presentation to Hierarchical via the Project Explorer menu, then exit.


- I "diff -r" the new and copied .metadata directories. That pointed me to org.eclipse.ui.navigator.prefs, where I found org.eclipse.ui.navigator.ProjectExplorer.activatedExtensions and org.eclipse.ui.navigator.ProjectExplorer.filterActivation.


- I added the following to our plugin_customization.ini file:

org.eclipse.ui.navigator/org.eclipse.ui.navigator.ProjectExplorer.activatedExtensions=org.eclipse.cdt.make.ui.makeTargets.content\=true;org.eclipse.ui.navigator.resourceContent\=true;org.eclipse.cdt.ui.navigator.content\=true;org.eclipse.egit.ui.changeSetContent\=false;org.eclipse.ui.navigator.resources.workingSets\=true;org.eclipse.team.ui.patchSyncNavigatorContent\=true;org.eclipse.team.ui.resourceContent\=true;org.eclipse.egit.ui.RepositoriesViewContent\=true;org.eclipse.ui.navigator.resources.nested.nestedProjectContentProvider\=true;org.eclipse.jdt.java.ui.javaContent\=true;org.eclipse.jdt.ui.javaModelContent\=true;org.eclipse.remote.ui.navigatorContent.connections\=true;
org.eclipse.ui.navigator/org.eclipse.ui.navigator.ProjectExplorer.filterActivation=\:org.eclipse.jdt.java.ui.filters.HidePackageDeclaration\:org.eclipse.jdt.java.ui.filters.HideOutputFolder\:org.eclipse.cdt.ui.navigator.filters.AnonymousStructFilter\:org.eclipse.ui.navigator.resources.nested.HideTopLevelProjectIfNested\:org.eclipse.cdt.ui.navigator.filters.ForwardDeclarationFilter\:org.eclipse.jdt.java.ui.filters.HideEmptyInnerPackages\:org.eclipse.jdt.java.ui.filters.HideInnerClassFiles\:org.eclipse.ui.navigator.resources.filters.startsWithDot\:org.eclipse.jdt.java.ui.filters.HideEmptyLibraryContainers\:org.eclipse.jdt.java.ui.filters.HideImportDeclaration\:org.eclipse.jdt.java.ui.filters.HideSyntheticMembers\:org.eclipse.ui.navigator.resources.nested.HideFolderWhenProjectIsShownAsNested\:


- I rebuilt our product, ran it with a new workspace, but Projects Presentation is still Flat.

- If I manually copy org.eclipse.ui.navigator.prefs in to the workspace and restart, then I see Projects Presentation set to Hierarchical.


I isn't clear to me why those prefs aren't customizable like the other preferences we've customized. Would appreciate any assistance.

Hi Nick,

I'm facing the same issue today with a product based on Eclipse 2019-03, did you found a solution past year to solve this issue?

Thanks by advance.

Hi Nick and Julien,

could you solve the issue?

I was running into the same behaviour as I want to hide resources starting with a dot.

Hi,

i would not call it solutions but workaround.

Modifying the jar files of the navigator:
https://stackoverflow.com/questions/6137848/eclipse-how-to-hide-custom-files-in-project-explorer

or defining your own extensions

plugin.xml
<extension
      point="org.eclipse.ui.navigator.viewer">
   <viewerContentBinding
         viewerId="org.eclipse.ui.navigator.ProjectExplorer">
      <includes>
         <contentExtension
               pattern="de.company.rcp.navigator.resources.filters.*">
         </contentExtension>
      </includes>
   </viewerContentBinding>
</extension>

<extension
      point="org.eclipse.ui.navigator.navigatorContent">
   <commonFilter
         activeByDefault="true"
         id="de.company.rcp.navigator.resources.filters.startsWithDot"
         name="hide resources starting with ."
         visibleInUI="true">
      <filterExpression>
         <and>
            <adapt
                  type="org.eclipse.core.resources.IResource">
               <test
                     property="org.eclipse.core.resources.name"
                     value="'.*'">
               </test>
            </adapt>
         </and>
      </filterExpression>
   </commonFilter>
</extension>

The contentBinding is required as otherwise the commonFilter definition wont be used. Make sure the pattern of the contentBinding and id of the commonFilter match.

Hi Martin,

This has been fixed in my company by a kind of workaround too. AFAIR something done at first startup. I don't remember how but clearly not clean enough to be proudly shared...

Since this time, the platform evolved a bit and thanks to Mickael Istria the associated defect is now fixed. See https://bugs.eclipse.org/bugs/show_bug.cgi?id=491185

Feel free to give it a try and post an update here and/or on the bugzilla ticket.

Hi Julien,

thanks to point me to the bug. As far as I understood the fix is only regarding flat/hierarchical project layout but not other settings as filters.

I was searching a bit more through the bugs and found https://bugs.eclipse.org/bugs/show_bug.cgi?id=558022 which should already (re)enable the filters by default.

The cause of my issue was an target 2019-03 as of December 06th (https://download.eclipse.org/releases/2019-12/201912061000/), the target as of December 18th (https://download.eclipse.org/releases/2019-12/201912181000/) includes the fix.

Thanks again for your hint.
Martin
