Eclipse launch configuration misleading - eclipse

How to I remove non-current Eclipse C++ launch configuration?
What I expect is, the RUN directly related to myproject.exe, not pointing to otherproject.exe sometimes. this is misleading and bring up error. So why not let the closed project with its launching configuration, i.e. closedproject.exe be invisible. And It should be automatically visible if I am editing that C++ code?
Yes I did check the menu setting (De-/Selected both tried):
Windows->Preference->Run/Debug->Launching->Launch Configurations:
Filter configuration in closed projects
Filter configuration inc deleted or missing projects
But the closedproject.exe still in the drop down list or sometime even link to current project build.
What did I wrong or what is the correct/clear setting for this? Or maybe pls. help me to understand why multiple project.exe are listed there?
Or it is a Eclipse improve point?

Thanks to #howlger I have found more insights on the toolbar settings of Eclipse.
In general, Eclipse default toolbar lineup are overdone for beginners like me. It should be more concise and turn-up only needed thus more intuitive.
The "Launch Bar" makes it explicit and standing out. But those build/debug functions/buttons are already in basic toolbar set, thus would be redundant or even misleading if people click on the drop-down menu of "Launch configuration", which is also not clean & clear in principal.
For that reason, the Launch Bar could be disable (for beginners):
Preference=>Launching=>Launch bar | right panel=> uncheck
Enable the Launch Bar
The red-squared button of terminate could be useful while debugging and re-build, because the previous malfunctioning RUN & program could still resident in task manager thus prevent further build and turn-up permission error, There helps this "Terminate" button instead of restart Eclipse. BUT as said, this button also in basic toolbar set. But it is often shadowed by the out-standing Launching Bar :-).
It is also possible to fully customize the toolbar (and lock it):
Windows=>Perspective=>Customize Perceptive
Then choose the tool bar items to display.
For the issue of multiple historical "launching configurations", I will report to Eclipse.

Eclipse Neon CDT missing manage configurations button

I created a C project in eclipse neon and I am trying to delete some of the build configurations. However I can not get to the manage configurations dialog I am used to. The button seems to be missing. Did it go somewhere else or is my eclipse just buggy?
I think this window is supposed to look more like this. See how there is a manage configurations button next to the dropdown at the top.
I just tried switching workspaces and when I use a clean workspace I can see the button.
While the aforementioned hacks indeed work, such an approach is impossible when one already has many projects and now wishes to target another architecture.
I have found another way.
Right click on the project and select, from the pop-up menu,Build Configurations, and one of the menu items is Manage. This behaves as the disappearing Manage Configurations button.
PS: this is still a problem with Oxygen 3.

Eclipse: workspace is completely invisible

Something quite strange has happened: The whole Eclipse main window disappeared while I was debugging a Play Framework project. The Eclipse symbol in the applications bar still shows up as usual (from where I still can force Eclipse to quit).
My System (Ubuntu 14.04.) still behaves as if Eclipse was there, e. g. other applications get unfocused when choosing Eclipse in the applications bar. Meanwhile I have re-started Eclipse (that didn't help) and even re-started Ubuntu (still the same behaviour).
When I start Eclipse the workspace selection window shows regularly up. If I select another workspace, it also shows up regularly (I have created a second one to test that). Eclipse even still reacts properly on any shortcut as well as well as F10 & F11. It seems like the Eclipse main application window was "transparent". Therefore I assume that it is a problem of Eclipse resp. its workspace rather than an Ubuntu problem.
Does anybody have an idea where to maybe re-configure the workspace? Or is there even a secret function for all that?
Thanks a lot!!
Meanwhile I was able to re-get the window: I clicked on a shadow effect that sometimes showed up. I resized that shadow with my mouse. As an effect the Eclipse window top bar (the one above the menu) showed up again. Afterwards I could "pull out" the window from the bar - and there it all was again... But I have still no idea, how that happened - and what might be the solution if someone runs into that issue without having a shadow.

Eclipse doesn't stop at breakpoints

Eclipse 3.5.2 is not stopping in breakpoints. It's as if the debugger is using an older version of the source file.
Tried the usual refresh, clean all projects, build all, with no change.
Already in debug mode and the break point is checked.
*ok ended up deleting the whole project and checking it out again. but still curious what the issue was.
Perhaps you have pushed the Skip all Breakpoints button in the Breakpoints view.
Thanks guys, this really saved my day too.
I antecedently pressed on skip break points, if you did the same this will result on break point appearing with a backslash icon on them.
To bring it back to normal:
Switch to Debug perspective.
press on the breakpoints view tap -->> upper right hand corner of the screen, you also can go there by Window->show view-> breakpoints.
5th icon from the left you will see break point with backslash. press on that one.
To confirm, try putting break point on any line, and it should appear normally.
Press Ctrl + Alt + B
OR go through below steps
Clearing all Breakpoints fixed the issue
(within debugger perspective: Window -> Remove All Breakpoints).
Rebuilding the project did not work for me.
Sometimes you do start the debug mode but the debugger doesn't actually get attached/gets detached. I've also had this issue a few times when my laptop was reacting really slowly.
A reboot always solved it for me.
Also try doing a clean all (works miracles in Eclipse).
Please un check this from the Eclipse Menu.
Run->Skip all breakpoints.
I think this will be enabled permanently once You select the Remove all Break points option in the Debug/Breakpoints window.
Performing a "Clean All" worked for me.
Click on "Project" tab --> "Clean" menu-item.
In the "Clean" dialogue-box select "Clean all projects" radio-button. Leave the remaining values as default. Click "OK" button.
BINGO!!!The remote-debugging started working for me as beautiful as before.
It has also happened to me, in my case it was due to the GDB launcher, which I needed to turn to "Legacy Create Process Launcher". To do so,
either change the default launchers to the "Legacy Create Process Launcher", in Windows>Preferences>Run/Debug>Launching>Default Launchers.
or choose this launcher in the debug configuration of your application (Run>Debug configurations>choose your debug configuration). Under the "main" tab at the bottom, click on "Select other...", check the box "Use configuration specific settings" and choose "Legacy Create Process Launcher".
I had a conditional break point wrongly put on the method entry point. Removed that breakpoint and it worked.
Note: Tried Skip all Breakpoints, Clean all projects, Refresh, close Eclipse with no luck before nailing it.
In my case, somehow the breakpoints got automatically disabled because of this switch turned on, skip breakpoints.
Breakpoints have seemed to work and not-work on the versions of Eclipse I've used the last couple years. Currently I'm using Juno and just experienced breakpoints-not-working again. The solutions above, although good ones, didn't work in my case.
Here's what worked in my case:
deleted the project
check it back out from svn
import it into Eclipse again
run "mvn eclipse:eclipse"
Since the project is also a Groovy/Http-bulder/junit-test project, I had to:
convert the project from Java to Groovy
add /src/test/groovy to the Java Build Path (Source folders on build path)
include "**/*.groovy" on the Java Build Path for /src/test/groovy
I had all breakpoints enabled and configured as I should. But whenever I clicked "debug" it would only step through the program (press f5/f6) Turns out there was a rogue setting
Right Click project > debug configurations > "Debugger" tab > uncheck "Stop on startup at:" box
One reason for this situation can be, that you have pressed 'skip all breakpoints', when play- and another pictures are smaller than those normally are (because of higher resolution screen). Another thing can be, that break points are stopped only under VM threads, not under normal threads!
Go to (eclipse-workspace)\.metadata\.plugins\org.eclipse.wst.server.core and delete all tmp folders.
Clean and Restart server.
In my case I had to enable then disable an option in the Preferences.
I don't prefer the debug view to keep jumping when a breakpoint is hit so I disabled this option, but caused the issue in question.
The solution was to enable it again, start a debug session, the breakpoint is hit and shown in the UI, then disable again the option.
Looks like a bug in Eclipse 4.17
UPDATE
There is also another simpler way that will make Eclipse show the debugging highlight at the breakpoint or rather refresh the debugging UI to work as it should. After the breakpoint is reached, Eclipse will ask you to switch to debugging mode if you are not already in, click switch button, then activate the debug tab/view, you will notice that the stepping buttons are activated and the breakpoint line is highlighted.
First remove all 'toggle breakpoints' from the class file.
Then Eclipse requires a restart.
Then make sure 'Skip All breakpoints' is NOT enabled. If it is, make it disabled.
Then, add toggle breakpoint to the lines in your file and run on Debug mode.
A pop-up window must appear to confirm if you really want to Switch to debug mode. Say Yes and proceed.
I suddenly experienced the skipping of breakpoints as well in Eclipse Juno CDT. For me the issue was that I had set optimization levels up. Once I set it back to none it was working fine. To set optimization levels go to Project Properties -> C/C++ Build -> Settings -> Tool Settings pan depending on which compiler you are using go to -> Optimization and set Optimization Level to: None (-O0).
Hope this helps! Best
I had the same problem, and I found the real cause.
I had written some concurrent / multi-threads code, while I added some breakpoints inside the code running in a new thread. So, when JUnit tests ran over, and stopped soon, the code will not reach and stop at the breakpoints.
For this situation, we have to click and select "Keep JUnit running after a test run when debugging" check box at "Debug Configurations..."
switching workspace worked for me.
Go to File > Switch Workspace and choose different folder (workspace)
That's it and BINGO! Debugging started working for me as beautiful as before.
go breatpoint and click on 5th to eclipse->window>->show view->other->debug->breakpoint and click on 5th option (Skip All Breakpoints)
Make sure, that you are using the correct JRE version to debug your project. Especially if it's a third party project.
Also make sure, that there is no trigger point set for any breakpoint.
I had the same problem when I was using Eclipse Juno.. I installed Eclipse Indigo and it works fine. Try to reinstall eclipse.
A different solution worked for me. I also faced the same problem - debug points were not being updated, though they are shown correctly in the IDE editor and in Break Points tab.
My problem and solution are: While creating the project, the 'Default Output Folder' points to different location. At a later stage, I have mavenized the project, selecting "Project Right Click - Configure - Convert to Maven Project". So there are two sets of output folders exist in my project file system. Cleaning the project multiple times did not solve my problem. In the background it was pointing to different binary files. Finally, when I removed the Maven Feature and cleaned the project, this time everything worked fine. Env: Eclipse Juno and JRE is J2SDK 1.5.
I get all breakpoints skipped and marked as warnings when using -O2 in the compiler flags. Switched to -O0 -g in my makefile and breakpoints now work. Hope this helps.
If it doesn't stop even after unchecking SKIP ALL BREAKPOINTS, you can add this android.os.debug.waitfordebugger just before your breakpoint.
If you do this,your app will definitely wait for debugger at that point everytime,even if you are just running your app,which it will only find when your device is connected to eclipse.
After debugging you must remove this line for app to run properly or else android will just keep waiting for the debugger.
Try to restart eclipse, that works sometimes. I guess there is some kind of cache there.
In my case the debugged code in JBoss was older than the code in the Eclipse project. Rebuilding the .war solved the problem.
Facing same problem with Eclipse Luna.
Project clean didn't work.
Rebuild didn't work.
What makes it work is uninstall the app on the device before each debugging.
I use the Eclipse FileSync plugin for live remote debugging. Make sure you tick Allow different target folders & edit the Target folder file setting in the tree view.
Setting the Default target folder by the Browse... button without Allow different target folders will set all folders to the same target (I had both libs & classes set to the default for libs so my breakpoints did not update).
Since Eclipse 4.7/Oxygen released in June 2017, there is a new concept of "Triggers for breakpoints", which is displayed as a small "T" next to the breakpoint "blue bullet" icon.
All the other breakpoints that are initially suppressed by triggers
will be hit only after any of the trigger points has been hit. All the
triggers are disabled after a trigger point is hit and will be
re-enabled after the run.
In order to reset all the "trigger" flags, you need to do the following steps :
Switch to Debug perspective.
Right-click in the "Breakpoints" view
Select "Remove All Triggers".
Note : this step does not delete all your breakpoints, which occurs when selecting "Remove All" in the same contextual menu.
Note : the keyboard shortcut to enable the triggers is "Alt-R", which takes precedence on the shortcut to open the "Run" menu with its mnemonics, when the "Breakpoints" view is selected.

XCode debug vs release build when debugging

Ok, i think i've seen it all now.
For about 24 hours i've been trying to debug my app, trying to find where all the weird crashes are coming from all of a sudden. I've been debugging via Simulator/Debug mode. As usual, when i hit a breakpoint, i could see the value of variables (most of the time). Then suddenly i was unable to view variables no matter what i did (btw, im talking about mouse-hovering as for some stupid reason my xcode disabled all the debugging tools from the debug menu).
Long story short, out of sheer loss of things to do, i decide to debug with Release mode. Now I can hit breakpoints and see the contents of my variables. And whats even more confusing is that now xcode gives me a much more comprehensive view of the variables that im 'watching' (hovering over).
I know Apple likes to do things different. But what the heck!? Can somebody please slap me and then tell me what im not understanding here?
First, the configurations "Debug" and "Release" are just names, you could also name them "Jon" and "Carla" if you want. They are just names for a configuration sets that you can modify and you can tweak them so that for example the "Debug" configuration is not suitable for debugging any more. So if you (accidentially) disabled generating debug symbols in your "Debug" configuration you would get exactly what you described.
Go to "Project" -> "Edit active target". Select the "Build" tab and select the "Debug" configuration in the drop down box on the upper left. Select "Show all settings" in the drop down box below and type "debug" in the search bar right next to these two drop down boxes.
There should be a setting "Generate Debug Symbols", make sure its check box is set. "Level of Debug Symbols" should be set to "All Symbols". Also, the "Debug Information Format" should be set to "DWARF with dSYM file".
After changing the settings, clean your project ("Build" -> "Clean") and build again.
Hope that helps.

How can I close an empty pane in Eclipse

I often end up with lots of empty panes in Eclipse that can only be minimized but not destroyed. How do I close these?
Update:
In this screenshot you can see two minimized on the upper left and several on the right hand side. In the center are four more. They only seem to be restorable in the Debug mode.
http://img406.imageshack.us/img406/9900/eclipse1.png
this happened to me, too. What worked for me (based on FilmJ and douncon's comments) was to open a class file, then drag that tab over the top of the empty pane.
Select Window -> Reset Perspective. That should reset the current perspective (what you call "mode") to its' initial state, (hopefully) closing all irrelevant views.
Something seems terribly wrong with your Eclipse. Maybe you should reinstall it. It is possible that you installed a buggy plugin.
First of all, what do you mean by pane? Eclipse has:
Windows (Eclipse itself, e.g. instance)
Documents (tabs)
Views (properties, tasks, explorer, etc)
If by 'pane' you mean document editors, you have problems either with your Eclipse version or most likely one of the installed plugins.
Each View also can be closed (except maybe some project types (perspectives) of which I'm not aware). For CDT (C/C++) you can close practically everything.
I'll recommend you download latest Eclipse version with no plugins, extract it to different folder, and check if that happens again. If yes, please explain more in details (like Eclipse version, perspective you are using, any side plugins, etc).
Also a good places are Eclipse community forum, mailing list and bugz :-)
I had the same problem. For me it helped to go into the right perspective and activate the functionality that caused the window in the first place. Once I reactivated the functionality, in my case "QNX Memory Analysis perspective", I was able to close all the windows one by one.
The conclusion is you have to refill the empty windows with content and then you will be able to close them properly.
So, it's really very easy for this to happen, if you open an editor that's incompatible with the existing editor, you can often end up having to place it outside of the tab list in one of your editor panes, then you might clear or copy that, typically while trying to add that view to a tab list.
In any case, what it's done is create a new editor, and all you need to do is drag some file to that empty editor window giving it some form of context, then close it.
I had the same issue. I followed #zvikico, but instead of just resetting, I first reset and then closed all the perspectives. Please follow the following to fix the problem. It worked for me:
Window -> Perspective -> Reset perspective..
After resetting follow below:
Window -> Perspective -> Close All Perspectives
