I am having tough time to figure out debugging UI parts of Eclipse. I couldn't find any information on google (or) Eclipse web site.
All I wanted to do is to find out the code that gets executed when we double-click a file in project explorer to open the file in Editor.
I tried to bring up Eclipse source code from Plug-ins view -> right click on the plugins -> import as Source Project. But, I am unsure what are all the components that constitutes to the UI part. I get some weird errors when I try to import everything that's found in plug-ins view.
Where can I find the information related to debugging Eclipse source code?
Instead of using Plug-ins->Import as Source Project, I would recommend opening the Plug-ins view, selecting all plug-ins, right click, and Add to Java Search.
Then you can use Open Type Ctrl-Shift-t to search for class names and the source will be attached so you can read it, set breakpoints, and debug.
In your case, I think you want to investigate IWorkbench, IWorkbenchWindow, and IWorkbenchPage. The openEditor(*) methods on IWorkbenchPage will be of particular interest.
You may also want to take a look at the org.eclipse.ui.editors and org.eclipse.core.contenttype.contentTypes extension points.

The momentics IDe for BB10 has encountered a problem or at least I believe that al my inclusions appears as unsolved. when I compile the app it compile correctly and everything works pretty well. But the problem is that I need to import some libraryes like #include and as long as this libreries are shown as insolved inclusion I cannot declare any object of those types.
Does any one know what can be this and how to solve it.
Things done berofe:
I've tried cleaning the workspace and creating a new project and also the new project works perfectly, also I've tried going to configure add and and some libraries. this works but only works for specific libraries, not at all for libraries.
Edit 1: As I saw on other posts, I've reinstalled the 10.1 sdk that is the one I need, but no luck
In the Workspace's Project Explorer pane, right click the project, and then select Build Configurations -> Set Active -> Simulator-Debug (Just to be sure.)
From menus, Window -> Preferences. In the Preferences dialog's left pane choose C/C++ -> Indexer.
To get intellisense to work when authoring well before making builds, under Indexer options, check boxes Index source files not included in the build, index unused headers, index source and header files opened in editor. And under indexing strategy check both boxes, automatic update and update after every file save.
Finally, under Build configuration for the indexer select the Use active build configuration option (Just to be sure.).
For class declaration in header file, the erratic feedback from IDE will disappear (as of Momentics 2.1.2) only after cpp file for implementation, that includes the header is saved.
If modifying header, after setting up as above, right-clicking on the project in Workspace pane -> Index -> Rebuild should work.
Hi I am going to dig a little more in Java so I would like to see how the program executed in the core class. For example, I would like to know how String.chatAt() is implemented, so I set breakpoint and tried to step into with debug mode. But I failed, I set bp at the second line when the program hit it, I used step into it still continue to the third line.
String a = "1231231241241";
char b = a.charAt(0);
System.out.println(b);
I think it should go into the source and show "no source found" and then give me a chance to attach the source file, right? But why it cannot get in? I can only use ctrl+right click on a method to get into source and attach.
It might be that your Eclipse is not setup to run with JDK, it might run with JRE instead.
Check this link.
Also, I might suggest you to try and use Maven for your Java projects management, it makes the life so much easier, when you get a grasp of it.
Most likely, you have the "Step filtering" functionality activated.
When debugging, it can sometimes be a bit annoying when the debugger steps into trivial classes whose internals you were not really interested in. Because of this, you can configure "Step filters". Classes or packages that are added as step filters will be ignored by the "Step into" operation.
If you want to configure which classes/packages should be included in the step filter, you can go to: Window --> Preferences --> Java --> Debug --> Step Filtering
My guess is that you have a java.* package filter defined there, meaning that the debugger will never step into any class within a package which starts with "java". Uncheck this package filter if you want to be able to step into java.lang.String
Alternatively, if you want to activate/deactivate step filtering completely, you can do this by clicking the Use step filtering button in the debug view, as shown below:
To be able to look at the code of libriaries you are using in your project you should configure your build path by attaching the soruces and JavaDoc.
Source Lookup
Seems like you dont have the "Source Attachment" set. Go to Preferences -> Java -> Installed JREs. Select the JRE you use and click "Edit", then set the Source Attachment to the src.zip that comes with the jdk by selecting the jars and clicking "Source Attachment" :).
You can do this with all of the jars at the same time by selecting them via shift-click.
for example in this System.out.println("test") piece of code if you want to step into System class just click on System and click F3 you will be redirected to attach the source code if you haven't already attached.Just attached the src folder of the jdk
First of, how can I see what plugin manages the CTRL + SPACE content-assist? And how can I modify it in other to add my own stuff. Any help/idea is gladly welcome.
Thanks.
I think you're looking for "Templates". Assuming you're using Java, this is in the Windows -> Preferences menu, then Java->Editor->Templates. For example, the screenshot below shows the CTRL-SPACE content assist when you type "sysout".
If i would have this task, I would go to preferences. Look for content assist settings. Write down some specific text you see in dialog box. Then go to plugins folder, and start to search inside archives. When match is present, open the plugin.xml of that plugin, and you will see the extension points of the plugin. Based on its name, I am pretty sure you will find the appropiate one. Then you can either google it, or look for plugins extending the extension point. Using JDGui or fetching source code of the extension example plugin will help you in disassembling. Eclipse usually not well documented as for extension points, so i do it this way.
This is my first attempt at an Eclipse plugin- the plugin architecture is vast and a little overwhelming, but I've found a number of tutorials and how-to's online which is helping, but trying to do the following is driving me nuts:
I want to add a submenu item that is available in the navigator context menu when you right click on an Eclipse project.
I can get a submenu to appear on a project file or folder, but absolutely no idea how to have it appear on a project.
Would someone be so kind as to provide me with step by step instructions, starting with creating a new plugin-project? This is probably a lot to ask, but I can't seem to find an online guide that has just the right amount of detail. I specifically want to use the plugin-project wizard rather than hand code a plugin.xml file as I am not very familiar with the Eclipse plugin architecture.
Ok- I got it- it was simple, but I got lost in the noise of the API-
Create a new Plug-in Project using the Plugin-Project Wizard and when the wizard has launched...
1.
On the Plug-in Project page, use anything as the project name and 3.5 as target platform eclipse version
2.
On the Content page, skip ahead and just press next
3.
On the Templates page, select "plug-in with a popup menu" and press next
4.
On the Sample Popup Menu page, you will see that eclipse has prefilled the field
"Target Object's Class" with a value of "org.eclipse.core.resources.IFile".
This means that when your popup menu will only appear when you right-click on a file in
a project. As we want the menu to appear when we right click on a Project when
we are using the Navigator view, simply use "org.eclipse.core.resources.IProject" instead
5.
Finish
You can validate that your pop-up will appear as expected by right-clicking the MF file
and "Run-as" > Eclipse Application
Now to refactor the resulting code to use menuContributions and commands rather than objectContributions and actions :)
I think you have a similar question (menu in the package explorer) here:
Renaming packages in Eclipse (thanks to Rich Seller)
This could be a good start, and is a complete plugin project.
You should look into the Eclipse Common Navigator Framework there are a few tutorials on this side that tell you what to do in detail The Project Explorer is an implementation of the CNF. You should also consider using the Platform Commands to add your commands (and popup menu item) to the popup menu associated with the project explorer. It's somewhat easier to use commands than actions. You should be able to do it with by adding a Command in your plugin extensions. Unfortunately off the top of my head I don't know the right incantation to have the command appear in the project explorer. But you will be able to find it in these resources.
If you press Shift+Ctrl+T or choose "Navigate > Open Type..." you get the "Open Type" dialog for quickly navigating to a known class. When you start typing a name only the classes for which the name matches stay visible. That way you can find a class of which you know the name very quick without having to browse through the package explorer tree.
This has been working great for me up until this morning. All of a sudden for a couple of my projects I am only seeing some of the types that exist. Of course I tried the obvious steps of refreshing the projects, cleaning the projects, re-building the projects, rebuilding the projects externally, but all to no avail. It is a bit odd since the types are known in other places. If I add an import statement Eclipse does not complain that it doesn't know the type and I can Ctrl-Click through the types to get to their file. However, the type navigation knows nothing about them.
In the past when InteliJ used to do this to me I would go find its cache files and delete them forcing it to rebuild. Does Eclipse have something similar I might do (I'm an Eclipse newbie)? I am using Eclipse 3.4.2 and I have it configured to not delete files on a clean (because our actual build process puts files into the output directories that I don't want Eclipse mucking with).
Have you tried closing and reopening the project? Only types from open projects are held in memory, and the refresh occurs when you Shift+Ctrl+T for the first time on a newly opened project.
Edit to add: Ctrl+Shift+R also displays the types (along with everything else) but it also supports the Camel-case thing to find the Java types quickly.
Close eclipse and delete any .index files and the savedIndexNames.txt file in workspace/.metadata/.plugins/org.eclipse.jdt.core once eclipse is restarted it will rebuildl the entire index for Ctrl+T
try starting eclipse with the -clean flag, you can add this to your eclipse.ini which can be found in the same directory as you eclispe.exe, or if you start eclipse using a bat or shell script, add it as a startup argument, e.g. eclipse -clean.
The clean will tidy your workspace, and should force eclipse JDT to recalulate types. Ive had issue with .snap files (with seem to be created on dirty shutdowns) that seem to corrupt my workspace until I clean them up, not long ago eclipse lost the Object class!! made for some interesting errors!
I get problems like this often. I tried your solution, noticed it seemed to rebuild its search index, but I still couldn't find any of my classes. Then I took a look at the little green arrow on top right corner of that dialog, and noticed I had a working set selected which belonged to another project. I find it a little dumb that Eclipse doesn't warn you about this or anything, since this can be a very annoying little detail that one tends to forget (me at least ;-)).
Anyways, clicked on "Deselect Working Set" and bam I can find my classes again. Thought I'd add this here since others may make the same mistake.
This worked for me -
Select your project in Package Explorer
Press F5 or Right click and select Refresh
I used the "-clean" as first line in the eclipse.ini (version Juno) and worked like a charm.
I'v tried all the answers and I still had the issue. I then tried this:
I deleted the project (it's a maven project) and re-imported it. This time I made sure i check the "Add Project(s) to working set" checkbox. After that Eclipse was able to find the classes in that project.
The problem must have started because I didn't check this checkbox when i first imported this project.
By the way, I'm using Neon
(Warning: Shameless marketing ahead)
If you like this feature, you would love nWire. nWire allows, among other things, to quickly search not only for types, but for any possible Java element like method or field. It also uses a navigator view which is non-modal. After searching you can see the class associations in a very quick and easy way. Check out the video on our site.
