CPP (C) Project not selected right click shows Build Project not enabled. (is Bug ?) [message #1707984]

When I unselect a project by pressing control key and left button of mouse, it appears as unselected not blue higlighted. Now When it is unselected if you right click the c/c++ project then the Build Project is not enabled. This doesnt appear at the Java project ! But only at c/c++ project.

This happens in case when the selection happens to be "<empty selection>" then the setEnabled(updateSelection(selection)) expression is false . But the debuging also shows that the same code line can get the IStructeredSelection as project itself. So when It is evaluating for this button the IStructeredSelection is <empty selection> at for class BuildAction.isEnabled() method line 239.

Please look at the debugScreen screenshot for more information.

is this a bug ? How can we solve it ? Please dont hesitate to ask for more information.

Yeah. That's strange and probably a bug.
When I tried it, the project became selected with the right click but Build Project was disabled in the context menu.
This condition remains until another project is enabled. The condition is also cleared by selecting the same project with a left click.

Yet another petty although easily circumvented annoyance to add to the rather long list of annoyances.

This happens similarly when moving a projects file and then pressing right click on the project to build it. Similarly When Includes is pressed and then right click to the project yields the same error. What should I do ? Should I open a bug at eclipse bugzilla ?

How can I programatically (or via eclipse plugin.xml) edit context menu of a project when It is right clicked in Project Explorer so that I can make the Build Action enabled in order to solve this problem.

I have tried MenuManager but it returns the top menu ? I want to acess the pop-up menu when it is right clicked on a project.

http://stackoverflow.com/questions/11410589/how-can-i-add-submenus-for-pop-up-menu-programatically

In this page above It says about IContributionRoot additions class and then it adds to this class via

  CommandContributionItem itemBB = new CommandContributionItem(pBB);
   itemBB.setVisible(true);
  additions.addContributionItem(itemBB, null);

This looks like a solution but how can I access IContributionRoot additions programmatically at the source code ?

Any idea ?

I solved the bug via an actionProvider (enablement for a instanceof IProject.) Here in the class that I extended from CommonActionProvider at the method setContext I got the command via commandService and getCommand method. Then calling buildCommand.isEnabled(); solved the bug.

Could you please share your code of the workaround ?

I can not share the code because We can not copy the code out of the computer. But I will like to answer your questions, I have posted the solution in previous comment. Where have you got stucked. Simply do a new actionProvider in plugin.xml there enable it for every IProject type.

Then in the method setContext of class that you extended from CommonActionProvider that pointed it at plugin.xml where you added the new ActionProvider, simply call the buildCommand.isEnabled().

get the build command via commandService and getCommand method.

Check this link to get the CommandService.

http://stackoverflow.com/questions/17061426/how-to-get-icommandservice-object-when-workbench-is-not-available

Command command = commandService
.getCommand("alexandraniculai.commands.myToggleCommand");

here you have to type the command Id which is :

IWorkbenchCommandConstants.PROJECT_BUILD_PROJECT for this command.

Please dont hesistate to ask. This is a solution via eclipse plugin.xml not a solution to the bug itself in eclipse code.

hi, ilke

I'm facing same issue with Eclipse CDT 9.2.1. refer to your solution， but it is not working for me.

public class ActionProvider extends CommonActionProvider {
    @Override
    public void setContext(ActionContext context) {
        ICommandService commandService = (ICommandService) PlatformUI.getWorkbench()
                .getService(ICommandService.class);
        Command buildCommand = commandService
                .getCommand("IWorkbenchCommandConstants.PROJECT_BUILD_PROJECT");
        buildCommand.isEnabled();
    }
}

   <extension
         point="org.eclipse.ui.navigator.navigatorContent">
      <actionProvider
            class="com.templates.ActionProvider"
            id="com.templates.ActionProvider">
         <enablement>
            <instanceof
                  value="org.eclipse.core.resources.IProject">
            </instanceof>
            <or>
               <instanceof
                     value="org.eclipse.core.resources.IProject">
               </instanceof>
            </or>
         </enablement>
      </actionProvider>
   </extension>
   <extension
         point="org.eclipse.ui.navigator.viewer">
      <viewerActionBinding
            viewerId="org.eclipse.ui.navigator.ProjectExplorer">
         <includes>
            <actionExtension
                  pattern="com.templates.ActionProvider">
            </actionExtension>
         </includes>
      </viewerActionBinding>
   </extension>

The above is the implement of class and plugin.xml. Could you please help me to check code above?
