I'm using Eclipse Indigo on Mac 10.7.4. While working, I get these periodic, annoying dialogs
'Periodic workspace save.' has encountered a problem.
Could not write metadata for '/.org.eclipse.jdt.core.external.folders'.
/Users/davea/Dropbox/workspace/.metadata/.plugins/org.eclipse.core.resources/.projects/.org.eclipse.jdt.core.external.folders/.markers.snap (No such file or directory)
I seem to be able to continue as normal, but I was wondering how I can eliminate these errors.
I had the same problem.
'Periodic workspace save.' has encountered a problem.
Could not write metadata for '/External Files'. D:\java\fuentes\.metadata\.plugins\org.eclipse.core.resources\.projects\External
Files\.markers.snap (El sistema no puede hallar la ruta especificada)
I created the folder "External Files" and it worked fine. In a few minutes the files ".markers.snap" and ".syncinfo.snap" appeared in this folder and the message didn´t appear any more.
I fixed mine by closing eclipse and deleting the whole .metadata folder inside my workspace folder.
Today I faced the same issue consistently, whenever I exit the eclipse.
While trying the above solution provided by TS.xy, the below steps got rid of this issue for now.
Switch to new workspace and close the Eclipse.
Open the Eclipse with new workspace and after that switch to the actual workspace(in which
exception occurs).
Actual workspace loaded with all my previous projects.
Now exiting the Eclipse, does not result in that exception.
Hope that this step may work for someone.
Just for another data point, none of the above helped my situation. The way I finally got past this issue is that each time Eclipse complained about some folder not being there, I went on my hard drive and created the folder. E.g. after I see
Could not write metadata for '/servers'.
C:\...\.metadata\.plugins\org.eclipse.core.resources\.projects\servers\.markers.snap (The system cannot find the path specified.)
I create the "servers" folder (not the file inside it). This gets me to the next error. I went through 3-4 of these iterations (exiting Eclipse each time to force the save) before the issues went away.
HTH, Mark
This was simple for me -
Solution
(pre) the listed directory is not present, see pic
Run Eclipse, see the error shown in pic below. Close Eclipse
Create the directory (RemoteSystemsTempFiles) where it is looking
note: ignore the items in this folder (e.g. .markers), they are auto-generated
Restart Eclipse, problem solved!
Example Problem Message
Not sure why this took me so long to resolve, but quite easy now, and quite obvious in retrospect! ;)...
Using Ubuntu, got the same issue
I noticed that the owner of some of the directories in
~/workspace/.metadata/.plugins/ ...etc...
was root
changed owner to me and the error stopped happening.
Looks like the same sort of issue may be caused by multiple causes.
Close the Eclipse , Clear the .metadata folder completely.. Start Eclipse & Import the necessary project once again if your project references are deleted..
The solution that work for me is the following:
Delete .metadata folder
Restart eclipse
Solved it by setting workspace on a local folder, and set data from import project, from existing resources.
I encountered the same problem , my resolution was to rename the the folder name under the workspace folder. i.e. com.ibm.collaboration.realtime.alertmanager.embedded was renamed to com.ibm.collaboration.realtime.alertmanager.2embeddedxx and rebuilt my project.
In my case, because I've accidentally deleted my workspace folder, and I observed the 'Periodic workspace save has encountered a problem". To solve this issue, I just simply create a new workspace and load all my projects to the new one. Hope you can solve your problem by doing the same thing.
I also ran into this problem. My situation was a little different. I was using 'working sets' to group my projects inside of eclipse. What I had done was attempt to delete a project and received errors while deleting. Ignoring the errors I removed the project from my working set and thus didn't see that I even had the project anymore. When I received my error I didn't think to look through my package explorer with 'projects', opposed to working sets, as my top view. After switching to a top level view of projects I found the project that was half deleted and was able to delete its contents from both my workspace and the hard drive.
I haven't had the error since.
I had gotten a little too aggressive about removing some directories in my project area when I was running out of disk space, and deleted this directory. Eclipse can leave some huge core files if it crashes in your workspace directories, (I had 35 gig of them) so it's worth taking a look there in your workspaces occasionally.
Anyway, as per the problem I tried the 'create a directory' approach. And it worked.
I was also seeing this error when I closed Eclipse by the way, not only after the 'periodic save'. So the exit/restart was also part of this.
Note that the last item on the directory path specified in the error message is a file -- not a directory, so don't get confused here. Probably worth checking that the directory permissions are created correctly as well (as the other projects in the workspace I think).
Obviously this is a bug in the Eclipse code base, (creating the full directory path under the file that is being created), but had I not deleted it in the first place, I would not have caused it in the first place.
I have the same problem since yesterday. Yesterday, I fixed it by creating a new workspace and reimporting the projects. It seemed to work well, but today it started again.
So, today I created the folder and the file manually and gave the full permissions -rwxrwxrwx.
Seems to work again...
Close Eclipse. Open RemoteSystemsTempFiles folder in Workspace, and clear inside this folder. Again open eclipse and close, warn about .project. Press Ok, then open Eclipse.
Solved my problem that.
I ran into this problem today after they switched our anti-virus software to Kaspersky.
In my case, the platform is Windows 7. My workspace is stored on mapped network drive. The strange thing is that, even though this appears to be a permission issue, I could manipulate files and folders at the same level as the inaccessible file without incident. So far, the only two workarounds are to move the workspace to the local drive or to uninstall Kaspersky. Removing and re-installing Kaspersky without the firewall feature did not do the trick.
I will update this answer if and when we find a more accommodating solution, though I expect that will involve adjusting the anti-virus software, not Eclipse.
In my case, the drive I was storing my workspace on had become full downloading SDK updates full and I just needed to clear some space on it.
This happened to me because i deleted one of the resources files inside the .metadata folder in my workspace.
After trying all methods, deleting the .metadata folder in my workspace worked.
Infact, this nuke option seems to work when there are a lot of issues related to eclipse bugs. One such example is working-sets. Working-sets are extremely buggy(but useful) and it is there that most of my eclipse problems start.
Hope this helps someone.
I solved the problem switching the workspace.
Go to File (Switch workspace)
Select the destination and create a folder named Workspace
Run a Hello World and close Eclipse (notice that Eclipse creates the folder RemoteSystemsTempFiles automatically)
now copy all your projects into the new folder Workspace
Open Eclipse and if necessary (sometimes Eclipse does not show the projects) import all of them (go to File/ Open projects from File System)
After you exit the eclipse, there would be an specific failed reason.
Mine is that the DISK IS FULL so the eclipse can't write into it anymore.
Agree with #J-Dizzle,
I am a beginner in web-development and had a hard time solving this today.
Had similar problems when I was creating a SpringBoot project in STS.
Tried most of the solutions mentioned but they didn't work.
Tried removing .metadata folder and re-building my springboot project but still nothing worked.
NOTE : I had multiple workspace in STS and this error occurred after migrating a project from one workspace to another.
Solution : All you need to do is restart your eclipse/STS IDE and it will work just fine.
When compiling my Java project, I get this error in Other errors:
Description Resource Path Location Type
The project was not built since the source file /PROJECT/src/main/org/../ABC.java could not be read PROJECT Unknown Java Problem
Indeed, the file is listed in Package Explorer but shows only "Error retrieving content description. On the file system, the silent dir exists but not the file; git status is missing nothing. How do I resolve that compile error?
Simply restart eclipse, refresh all projects and do a clean build. That should fix it. Don't forget the eclipse restart, else no matter how many times you do a clean build or refresh, it will not fix the problem
Looks like someone has deleted that file but eclipse still think that file is part of the project. Might have happened when someone deleted a file from the source control in an improper way.
If you dont have pending changes then you can get fresh copy of the project and import it into your workspace.
If you have pending changes then take a copy of changes and repeat above step. ( A restart of eclipse may be necessary)
It can be related to missing location
Select File => properties => Resource => Edit file location.
I know the answer is accepted but in my case that solution didn't work for me, I had restored files from a backup to my local project in linux and the files I restored were owned by root with only the owner being able to read/write the files. SO, I sudo chowned the files "sudo chown _R myUser:myUser *" at the base of my project, refreshed in Eclipse (f5) and the annoying repeated failure of my build was a thing of the past.
If you are writing Maven projects, try right click on the project and select [Maven] -> [Update Project...]
It works for me.
For me there was a different solution than mentioned here.
I was doing a no-no, I imported a project that had a .project file, and there was some errors in the way my version of eclipse was reading some of the files. The package names and files had a little ! symbol with a yellow background.
The solution was to delete the packages. Obviously make a backup. But in doing this most times the files nor the packages were deleted. Instead eclipse refreshed and the desired files were there. Sometimes I had to hit refresh (F5), and sometimes I had to restore files.
I found it best to delete the packages as that is where eclipse was having reading the data.
If the missing file is still mentioned in the Linked Resources, no refresh and restart of Eclipse will ever solve the problem. You have to delete the file in the Project Properties Linked Resources list.
For anyone using VS Code with the RedHat Java plugins (which use Eclipse tooling under the hood), I got this error as well. I fixed with the following:
# Quit VS Code
rm -rf ~/Library/Application\ Support/Code/User/workspaceStorage/*
# Reopen VS Code
As all others said, it is most probably an issue with the internal caches of Eclipse.
I usually restart the IDE with the additional -clean option to wipe out the OSGi-related caches, then clean and rebuild all the projects.
If the problem persists, I realized that cleaning up the single affecting project works better that cleaning up the whole workspace. (Ominous... XD)
This usually happens to me when merging changes that imply renaming or deletion of source files, prior to launching Eclipse.
I run eclipse on Ubuntu 11.10. I originally created a project in folder foo. I subsequently deleted that project to re-organise folders and I now want to create a new project in folder foo/bar but Eclipse won't let me because it says the the new directory is a sub-directory of an existing project.
How can I force Eclipse to forget about the original project so that I can create the new one?
In general, the deleting the project from the "/.metadata/.plugins/org.eclipse.core.resources/.projects" should work, but if you're using 'working sets', you might have the problem I had once, which is basically have a 'ghost' project in your workspace that you can't delete because it says "this project doesn't exist anymore".
If this is your problem, try to delete an entry for your 'ghost project' in the file:
"/.metadata/.plugins/org.eclipse.ui.workbench/workingsets.xml" (on MacOS).
Delete the project from /.metadata/.plugins/org.eclipse.core.resources/.projects and not the whole .metadata folder will save all other projects and config.
I have also encountered this problem, except it's been in Windows. I didn't want to completely remove the .metadata folder and none of the other solutions fixed it.
I managed to fix it by removing the file workspace\.metadata\.plugins\org.eclipse.core.resources\.safetable\org.eclipse.core.resources while Eclipse was closed. The file gets saved when closing Eclipse so I guess it is cached while Eclipse is open.
Go to your workspace folder using some file manager (you can find your workspace location, be clicking File -> Swich Workspace...) and delete your foo folder, or simple remove its contents (.project file being most important). Then you should be able to create your new project.
I finally managed to fix it by deleting the workspace/.metadata directory. This resolves the problem but has the side effect of making eclipse forget everything about the workspace so I'm not sure it's a recommended way of fixing the problem.
I am running Eclipse Kepler on OS X Mountain Lion, and I had a similar problem. I deleted a project and tried to recreate it in the same location. Eclipse gave me an error saying that the project already existed. I discovered that if I close Eclipse after deleting a project, then reopen it, Eclipse finally 'forgets' the deleted project and allows me to re-create it.
(This question was posted over 1.5 years ago, and I'm guessing that Bruno already tried this and it didn't work. I just want to let others know that this solution worked for me now on Kepler.)
I had the same problem, with Egit and repositories that I deleted and imported back again, instead of importing as general project choose import as existing project.
maybe you can try to delete the folders:
"/your_workspace/.metadata/.plugins/org.eclipse.core.resources"
"/your_workspace/ProjectName"
If the Project was in a working set before you deleted it, you might have to manually remove it from the set.
Instead of deleting any file, rename it, so if whatever you try doesn't work, you can revert.
Eclipse was working fine just a day ago. But today, when I click the eclipse icon, it only loads the splash screen and nothing else thereafter, I even don't get to see the splash screen which contains that 'green loading sign' at the bottom, and -- while monitoring the eclipse.exe in Windows Task Manager(just after starting eclipse) -- I saw that even after the splash screen went off the screen, the eclipse.exe process went with it, after a few seconds. Keep in mind that I did NOT see any warning or error messages because, (I'm assuming, that the loading haven't gone to a point where it is capable of sending any error message)
Hence, I tried reinstalling eclipse, by copying from INSIDE the .zip directory of the installation folder and pasting it inside the eclipse program directory. But the exact same problem persists. So, now I'm currently downloading the latest version of eclipse to retry again.
Any other Advice?
UPDATE
It turned out that the hard drive containing the workspace was partially corrupted, hence I cleaned it; following that, the workspace data was still accessible. (Though usually I still keep a backup on hand.)
just delete the .metadata folder from workspace and reload the eclipse. It worked for me.
Hoping you have the links to the update sites for your installed plugins, my advice is to download eclipse, download your already installed plugins from their update site's and then open the new eclipse and set the workspace to your actual workspace. More far than that is to trash your time... trust me.

Probably something went wrong with Java. Try re-installing Java run-time.
It also can mean a problem with the eclipse.ini file (like an extra space at the end of the line), or a problem with the JVM path (since the splash screen is displayed by the eclipse.exe, before loading all the eclipse Java classes).
Check that eclipse.ini file and consider my ini file as a good optimization source.
If your workspace has been corrupted your safest approach is to create a new one.
I would actually strongly suggest that you reinstall everything that might have been corrupted, to avoid as much strangeness as possible. This includes the underlying OS.
I have tried out both
(1)E:\eclipse-standard-luna-RC3-win32\eclipse -clean in run
(2)deleting .metadata folder from workspace
I do not which one worked for me.Thanks...
I was just working on my Netbeans project and accidentally deleted it and don't know how to recover it.
Is there a tmp folder that the deleted project is stored in.
Or am I forever doomed?
Thanks,
Lucas
Do not panic. Its very easy. Follow the steps:
Right click on the folder/directory that the files had been deleted.
Choose Local History – Restore Deleted
Done
If you accidentally delete a folder on Netbean, the way to recover it is as follows. You can't revert deleted folders but you can revert deleted files. Follow these steps.
Recreate the folder you deleted in your Netbean project. (You may not be able to create the folder within Netbean, in that case you can use mkdir command to create the folder )
Right click that folder in Netbeans and go to History -> revert deleted (you should see a list of deleted files that relate to that particular folder.
Repeat for each folder and sub-folder
Note: I do not know if this works on windows, I know it worked for me on Linux. I also don't know if this works after you have closed Netbeans.
hope it helps someone.
You have a problem of package/directory/file deleted in netbeans?
Don't panic it is simple just:
open your netbeans IDE
go to projects
go to the package where your project folder was
right click on it
go to local history, then go to revert deleted
it is done. Wait a moment!
I think it will help you.
Enjoy your code please.

saved me countless times when I first started with Visual C# opening the IDE and making mini programs without saving. All your files are stored in a temporary folder and exiting Visual C# wipes them. Just do a recuva scan and sort files found by modification time. Deleted files are recoverable, overwritten files however are a different story, so run the program as soon as possible.
Actually, easier then trying to load a project that does not exist in the project explorer of netbeans.
If you still have the files locally, just choose Open Project and your lost project will be restored to the Project explorer of netbeans.
I don't know if there is a temp folder. Windows search engine doesn't work to find it. If you delete the source file by using safely delete;
On Netbeans Refactor-Undo[Safely Delete] option can be used to recover...
