I want to write an Eclipse plug-in that adds an item to the Refactor menu in Eclipse JDT? How can I do this?
Thanks a lot
Recently, I was writing a plug-in that performs some re factoring.
Writing the refactoring was not too complicated, but figuring out how add the menu items correctly into the Refactor menu took a lot of time.
Here is the correct plugin.xml snippet:
The Refactor menu tag is a copy of the original "Refactor" menu definition from org.eclipse.jdt.ui. It is important to copy all the separator definitions. For my plug-in, I have also added a new separator called spartanGroup.
The path for the Refactor menu is org.eclipse.jdt.ui.refactoring.menu.
It is possible to figure this information by looking at plugin.xml of the org.eclipse.jdt.ui plug-in. You can find it online (for example here) or you can import the source code of your eclipse build following these steps:
1 File -> Import
2 Select Plug-ins and Fragments and click next.
3 In the "Import From" section choose "The active target platform".
4 In the "Import As" section choose "Project with source folders"
5 In the next screen, locate your plug-in (org.eclipse.jdt.ui) and add it.
6 Click finish and the source code of the plug-in will be imported into your workspace.
You could write a plug-in that utilizes the Platform Command Framework. For details see the official wiki page, that provides several tutorial links: http://wiki.eclipse.org/index.php/Platform_Command_Framework
Basically, you define a command to execute, a menu contribution (where to display it) and a command handler (what to execute).

I have copied my src package structure from eclipse to intellij and it makes this structure within src folder:
How do I make it dz1.drugi so I can one click expand all to my classes?
Another question is how to select default project folder as it is "workspace" at \Users\{Name} for eclipse. Right now, when I create new project like this:
it saves it without workspace (or projects folder) at \Users\{Name}.
Click on the cog icon at the top-right of the explorer view, and check the "Flatten packages" option.
That said, If you get used to keyboard shortcuts top open classes and files, and navigate through recently opened files, you'll quickly see that you'll amost never use the explorer view anymore.
Project view has an option to compact empty middle packages, enable it. You can also use Flatten packages option. Actually, your question is a duplicate of this one.
IntelliJ IDEA remembers the last location you've used when creating a new project. Once you want to create another project, the location one level upper of the previous project directory would be suggested. So, create a project in C:\Users\someuser\workspace\myproject1 and IDE will suggest C:\Users\someuser\workspace\myproject2 for your new myproject2.
I am using eclipse 3.6. I created one sample plugin application. It is neither a eclipse rcp nor workbench. Now when I run the eclipse I want that plugin also to be loaded. But I dont want to use IStartUp. Because what I have found out is
IStartup will be called after the workbench is loaded. I want to refresh some menu. So Is there any way to activate my plugin while the eclipse loaded?
I tried to use Bundle Activation policy. But that is also not activating my Activator class. I just put one System.out. println("Inside start()"). So that is not called. Now can I make it activate my activator?
EDIT:
what my exact requirement is, I have created one workbench application.It is not eclipse rcp application. Now I want to remove the following menu and menu items from the eclipse before the eclipe is loaded.
1. File Menu
2.) Search Menu
3.)Run Menu
4.)Help->search,Dynamic Help,Key assist,Tips and trick,Report Bug,Cheat Sheet.
These menus are inbuilt menu of eclipse. So that is the reason I have to do in this way.
So I already implemented by using startup extension point. But the early startup is called after the eclipse is started.So I need to do some refreshment on the workbench.Then only the menu item will get removed.So I thought I need startup extension point will not satisfy my requirement as it doesnot refresh the workbench.I need to activate the my plugin and refresh the workbench before it is loaded.
Thanks

You can set the needed start level for your plugin using touch point instruction.
You are just a plugin that expects to run in the Eclipse IDE?
Then the answer is, you cannot do what you want.
If you start before the workbench has finished initializing, most of the services that could be used won't work: The workbench itself, menu service, command service, etc.
For most plugins in eclipse, the plugin.xml should be used to add menus, views, editors, etc to eclipse. When necessary, the framework will instantiate them.
org.eclipse.ui.IStartup is available and as you mentioned it will be called after the workbench has been initialized, but before any windows have been shown. It's not to be used lightly, and not by plugins contributing to the UI as it allows all extension from that plugin to be loaded.
EDIT:
If you are an RCP app, you control the main menu. As an RCP app, you have access to the ActionBarAdvisor, WorkbenchAdvisor, WorkbenchWindowAdvisor, which all have lifecycle methods.
If you are an an eclipse plugin, you can add to the main menu ... you cannot easily remove from the main menu. This is by design. Start levels and org.eclipse.ui.startup are 2 mechanisms that won't do what you want.
You still need to answer these questions:
There might still be a way. The crux of your problem is: "I want to refresh some menu"
What kind of menu (popup, main menu,
compound list of menu items in a
menu, etc)?
Where is the menu contribution coming from?
Which specific menu item is it?
Please edit your question (do not comment) and include the information from the above 3 questions, please.
i am making an eclipse plugin which make a ui on right clicking a project in eclipse workspce . the ui contains text fields , package explorer for the current project and directory explorer for current project.
i have successfully made a ui which appears on clicking a menu item on right clicking the project but it seems i can't make any jface or swt ui since they are not visible when we are using eclipse command hadlers .so in order to overcome it i made dialog pages but they have limited dialog like directorty dialog and file dialog and that too for entire window directory..... but i want package explorer and directory explorer for the project i just chose like it happens when u try making a new class in a project the browse buttons just show packages and directory struture w.r.t to current selection
am i doin things wrong or is there a way out please suggest .....
It seems a bit unclear to me, what the 'UI' is about. If you plan to embed the package and directory views inside a dialog next to each other, then I think you have to build similar lists on your own, since they are views with their own event logic. But if you plan to use them via the browse buttons as describes, take a look at this page. It gives a good overview of the available selection dialogs in eclipse.
It is also always a good practice to search for code in eclipse that does nearly the same you want to do.
As an example, take a look at the new class wizard from the jdt.ui plug-in (This is the wizard you mentioned in your question): Press Cmd-Shift-T and begin typing 'newclass' and open NewClassWizardPage from org.eclipse.jdt.ui.wizards. This works as expected if you imported all jdt plug-ins as (binary) projects.
Take a look at the createControl method and dive into the createXXXControls methods via F3 and try to find out how JDT is doing the job.
As an alternative, open the desired selection dialog class (again with Cmd-Shift-T) and open the call hierarchy of that class...
Eclipse currently shows the task tags (// TODO) from all open projects. I would be grateful if anyone could point out the preference, where I could restrict the scope of tasks displayed (e.g. only tasks from current project).
In Eclipse Helios (3.6) you can configure the scope.
Down arrow at the top right -> Configure Contents:
Select a configuration on the left (or create a new one) and on the right in the Scope section select "On any element in same project".
There should be a down arrow in the top-right with several options in it. For the old Eclipse the option you want is Filters... And for the newer Eclipse the option is now Configure Contents. At the top of the Configure Contents dialog is a scope selection with options you want, I think.. If not check preferences and search for tasks, or scope. It should be in there somewhere.
Close projects that you aren't working on. Tasks show for any part of the workspace, so remove projects that you arent working on by doing a close operation. (right click on the project in the project explorer and then "close project")
Configure Contents... can be used to filter to things like working sets (if you're not already using working sets, you should), but yet another way is to use Mylyn to filter out any UI elements not relevant for what you're currently working on.
In Eclipse 2019-06:
1- Open the Tasks window.
2- Click on the arrow pointing down ▽.
3- Click on Filters...
4- In the Configurations panel on the left select TODOs (or any configuration that you have saved).
5- Under Scope select On elements in selected projects
6- Click on Apply and Close
Now the task view will only show the tasks of the project where you are at the moment.
Simply close the projects you are not working on.
You can leave them in the workspace, too.
In Eclipse Juno 4.2.1, I found that it's possible to disable specific projects TODO tasks.
In the projects properties open:
Java Compiler > Task Tags
From that page check the option "Enable project specific settings" and remove the TODO entry from the list below, after that the TODO comments from that project won't be shown in Tasks.
You could also remove other tags from the list.
Filtering by working sets works fine, but I had to put the packages into a working set, rather than the whole project.
AFAIK the Eclipse task list is workspace-based and cannot really be filtered by default.
I have what appears to be a very annoying problem. When compiling a project in Eclipse, I see no Console that shows the invocation of the Java compiler and the build results (as in NetBeans).
If I, for instance, import an existing project into Eclipse and invoke Project->Build Project, is there a view that will show me results of the compilation? While I know that my project contains a number of files that have errors, invoking Build Project shows no visual result/progress of the compilation. It does not show the list of errors so that I can quickly jump to them.
I'm aware that there is a "Problems" view, which shows a list of problems (and not just compiler errors) in all projects and not the particular project that I am working with, which makes it very inconvenient to locate and jump to source of the problem.
You can configure the problem view to show only problems in the current project:
Click on the small triangle at the far right of the view.
In the popup menu, select "Configure Contents..."
Select each item in the "Configurations" list and click on "Scope: On any element in the same project"
If you want to see the compiler working, you need open the "Progress" view.
Since Eclipse JDT provides its own built-in Java compiler, you generally do not see the invocation of Java Compiler.
The built-in Java compiler is tightly integrated with Eclipse and JDT, and provides the source indexing that enables powerful IDE features such as refactoring and quick fix.
Plus, it enables incremental build in background after each file modification, hence no visible "java" invocation.
You can replace/complete the java compiler with a javac` call of your own:
For instance, Using Alcatel-Lucent nmake with Eclipse JDT does precisely that, and uses a configuration launcher (which you can instruct to show a console):
You will need to add that special builder in the "builder" section of your project.
Do not forget you can create many "Problem view", and set one of them to show only problems for your current project.
Select: "on any element in same project"
Goto Windows->Show View->Console
or
Alt+Shift+Q,C
Console appears in tab with Problem view
Your question contains a couple of assumptions that you might want to re-think.
It does not show the list of errors so that I can quickly jump to them.
Errors are flagged in the edit window while you are editing. You can fix them on the spot, without having to "jump" anywhere.
If you drop an entire source file into your project, you may not be in an edit window on that file. (And, of course, that's not standard Eclipse usage.) The simplest way I know do deal with that is simply to "Refresh" the project and look in the Package Explorer view to see whether there are any errors detected (which will happen immediately if you "refresh" a file into a source folder). Double-click on any files which show an error icon and look at the right-hand side of the edit window to see exactly where the errors are.
I'm aware that there is a "Problems" view, which shows a list of problems (and not just compiler errors) in all projects and not the particular project that I am working with...
Unless you are using multiple projects, with inter-project dependencies, I find it useful to close all but the current project on which I'm working. Then the "Problems" view is specific to the current context.
Finally, I'd recommend looking at the Mylin "getting started" page for other hints on how Eclipse can help you focus on the current task.
