I was adding a simple file to one of my programs that updates when I run the program with a particular parameter.
The file updated fine, but it is stored in the /bin directory and I can't figure out how to view the file within the editor.
I can see that the file is updated when I traverse the bin folder manually and open it with notepad.
Is there a way to view the file within the editor?
edit: I have a file in the project already but I doesn't update, instead the copy in the bin folder does; Can I connect the two somehow?
Your <project>/bin directory is being filtered from view. Right click on your project, select Show In->Navigator then you should be able to see your /bin directory and double click your file to have it open in an editor.
Alternatively, you can use ctrl-shift-r to open the Open Resource dialog, from the triangle drop down menu check Show Derived Resources, and then type in the name of your file.
The /bin directory is managed by the Eclipse builders and so you may lose your file if you do a clean. I would suggest using a different directory to house your runtime files.

I am using vscode for java and c++ projects.
In both cases, when I want to open a file with quick open (ctrl+P) the file appears twice.
One time marked as 'recently opened' with relative path to my workspace and
A second time with an absolute path in home (~/home/harri/...)
It seems as vscode manages the files twice generally. I think so because if I opened a file from project explorer and go to a methods definition (command: Go to Definition | F12) then the file is opened a second time. I can see in the files editor tab that the paths do differ. One relative path one with absolute path.
Is this a problem of my settings?
I am running vscode 1.74.3
I try to execute a jar file in the command prompt, but I always get the message 'no main manifest attribute, in 2056751-0.0.1-SNAPSHOT-src.jar'. So, I guess I should edit the manifest file. If I check it in the command prompt with the command 'jar tf 2056751-0.0.1-SNAPSHOT-src.jar' I can see that there is a MANIFEST.MF file, still I cannot see it in Eclipse project view.
To partially answer the question asked, IF on Windows (which you didn't say and isn't the only system with a command prompt), a jar file is really a ZIP file underneath and Explorer in all supported versions (>XP/S03) can treat a ZIP file as a directory subtree, so just rename to have the extension .zip and open in explorer, go to META-INF, select MANIFEST.MF and open with plain-text editor of your choice such as notepad. However this may not allow you to edit; if so copy to somewhere writable like the desktop, edit, then copy or move back. Then rename back to .jar
Although the manifest file in a jar can be loaded from an actual file, usually it is created by the jar tool. If you want a jar containing classes to run from the usual file association on Windows use the jar tool with the e option as described in the man page or Windows version on the web and help message. However if your file name is accurate and this is actually a source jar, it will never be runnable by only changing the manifest and you need to learn how Java works.
In my xcode project i have created a folder manually named "MyClasses" to place the newly added files/classes to this folder.
Now i have nearly 30 classes in this folder.
when i renamed this folder , all the files in this folder are gets Erased.
Now i need to rename the folder to "ViewControllerClasses".
But i lost 30 .h, .m, xib files. [lucky i have a copy & and zip file]
How to rename the folder with out corrupting the files.
Renamed it to myviewcontrollerclasswes
When i renamed
Two Solutions
Method_1. Try Manual editing:
« Drag your MedChart.xcodeproj to TextWrangler (or any text editor)
« Use find button to find "FolderName" (Your folder name)
« Replace all with new name.
« In some project you may notice header search path problem...goto header search path and replace with new name.
Method_2. Use Xcode to choose base folder:
Rename folder in finder then use Xcode to choose same folder.
NOTE as of 2017:
Now Xcode 9 synchronises the folder and the project hierarchy automatically.
NOTE as of 2013:
Duplicate and rename Xcode project & associated folders
The "folders" what you see in XCode under your project file are not real folders in the file system, only virtual folders administered in the .xcodeproj file. You can organize your files in the project folder independently from their location in the file system. Some prefers to map the file system folder structure inside the project folder structure, some others store all source files in one big folder in the file system and organize them only in the project folders: it's rather a question of preference.
However if you rename/move physically the files in the file system, you will have to delete and re-add them to your project since XCode will not know where to find them. Pay attention not to delete them physically only remove them from XCode project, then re-add them and reorganize as you want.
One more thing to note: if you are using version control system you will have to inform also its client (svn or git most likely) that you have renamed/moved your files. If you want to keep file revision history it will be a good idea to issue the copy/move command explicitly to the version control otherwise it will treat your files as deleted from the old location and added as new in the new location.
In case anyone is still having trouble with this:
Select the folder or file in the left-side bar of XCode corresponding to the folder you want to rename (for me I renamed the folder containing all my files so I selected the topmost folder)
On the right-side bar, below where it says 'Location', click the folder icon.
In the file explorer that opens up rename the existing folder to whatever name you'd like it to be, then afterwards select it and press 'Ok'.
XCode should update the file locations accordingly.
Keep in mind that if you rename something which contains a file that is hard-coded as a certain path in your build settings, XCode will throw an error. You'll have to manually change those paths in your build settings.
This worked for me, hope it works for you too.
You should just run a search and replace on the project file (if you are working with version control and with other developers you will have seen this file a lot without a doubt), it's the project.pbxproj file located inside the xxxxxxxx.xcodeproj file.
Just right click (Control + Click) on the file and select "Show Package Contents" to find the xcodeproj file.
I still find it easier than all these methods to simply create a new folder in your file navigator and then drag your files from the other folder into it. Sometimes the simplest way is the best way. It literally takes me 10 seconds and I don't need to leave Xcode.
Is there a way in eclipse to make the project's output folder an external folder, instead of a folder located under the project root?
Yes, you can define it as a linked folder.
This this SO answer for more (or this one)
To create a new linked folder select New->Folder, input bin in the folder name: field then click Advanced>>
Click Link to folder in the file system
Click on Variables... to bring up the Select Path Variable dialog.
If this is your first time, or you are linking to a new location select New... and give the variable a sensible name and path.
More precisely, you define your output directory (say 'bin') as a linked folder, then you set that directory as the official output one of your project.
I use Aptana Studio (based on Eclipse). I'm trying to get Eclipse to completely ignore an entire directory inside a project. I mean COMPLETELY. I don't want it to display in the project folder. I don't want Eclipse to even be aware it exists.
Unfortunately, all my efforts to add it as a filter don't work. See http://forums.aptana.com/viewtopic.php?f=14&t=8340#p33714 . I think the filter only prevents the folder from being displayed in the project display. It doesn't keep Eclipse from actually looking at all the files in that folder for code assist, etc.
My problem is that directory has thousands of text files. So, each time Eclipse opens or refreshes this project, it analyzes all those files.
How can I prevent this?
Not sure about this aptana thing, but there is a convenient way to do it in native eclipse:
Right-click a project folder in Project Explorer tree and go to "Properties".
Resource -> Resource Filters.
Add as much exclusion filters for files/folders as you like.
If your project tree is not refreshed immediately, press F5 to enforce it.
Consider also the 'Derived' checkbox: right-click an entry in the package explorer, choose properties, check Derived. This may solve part of your problem.
See http://robmayhew.com/eclipse-ignore-folder/
If you have a linked resource (pointing off to some other file/folder on disk) with the same name in the same location in the resource tree, then the real folder on disk will be hidden from the resource model.
Unfortunately you can't create the linked resource if the real directory is already there in the project structure. You can try something like this:
On disk, rename/move the directory in question
Refresh the project, the directory is gone
Create a linked resource ( New -> File/Folder >> Advanced -> Link to file in the file system ). Name it the same as the original directory.
On disk, restore the original name of the directory
Refresh project.
Try right-clicking "Properties" and unchecking all permissions.
