I received an error about how Eclipse was caught in a loop and something about garbage collecting...after I finally got it closed, I tried reopening and it won't work. I tried the following from the command line:
eclipse -clean
and it still doesn't work. I posted the error log at
https://docs.google.com/document/d/1EPwYgHujbD8fX-W-b1DatJutgNv-ZnIkm8SP180R4XQ/edit
This is a fresh error log (single attempt to open eclipse)
Anyone know about eclipse errors that can help me out?
Delete the .metadata folder from the workspace or change the workspace folder.
To make the eclipse ask where should your workspace be follow the steps below.
Find the file org.eclipse.ui.ide.prefs in your eclipse\configuration.settings folder.
Change SHOW_WORKSPACE_SELECTION_DIALOG=false to true.
I had a similar crash and starting eclipse with -clean option did not help. I ended up deleting the .metadata\.plugins\org.eclipse.e4.workbench file, which fixed this problem.
Sometimes your workspace becomes corrupted and Eclipse can't open that workspace.
Can you open/create another workspace?
I ended up just reinstalling eclipse...
I was getting an issue where Eclipse wouldn't start. The splash screen appeared for a second, but never showed the workspace select screen, just like the OP said. I was about to reinstall when I took one last look at my eclipse.ini file. I found that I had left the m off one of the memory allocation settings. This caused it to crash with no error messages. So, perhaps malformed ini files can cause this issue.

I installed e(fx)clipse over my existing Eclipse Mars installation using the update sites given here: https://projects.eclipse.org/projects/technology.efxclipse/downloads
The installation worked fine, e(fx)clipse also seems to be loaded (load screen on startup changed). But when starting Eclipse, I get the following error displayed after selecting the workspace: "An error has occured. See the log file [...]".
Can anybody help me with this? I would add the log file, but I'm new here and I don't know how to upload.
Thank you very much.
I now solved the problem by myself. I don't know exactly what the problem was, but it seems as if workspace settings were a problem. I deleted the whole workspace directory so it was recreated, and that method worked out fine. I also installed a more recent version of the jdk1.8, but I don't think that was a problem since I also got the error after installation and before I deleted the workspace directory.
I'm trying to open my Maven project with Eclipse Juno, but I'm getting this error:
An internal error occurred during: "Updating Maven Project".
Preference node "org.eclipse.wst.validation" has been removed.
How is this caused and how can I solve it?
Same probleme here, there the solution I fix it
Open the .project file with your prefered text editor.
delete the node that is about "org.eclipse.wst.validation"
Close your project
Open your project
Launch Maven Update...
Should be good.
Another way to fix it, if you don't want to change your .project config
(or if you had several projects that must be fixed)
Close your workspace (or eclipse)
-move out <WorkspaceDir>\.metadata\.plugins\org.eclipse.core.resources\.projects from the workspace directory
-reopen you workspace
close it again
-move back the .projects dir (say yes to replace questions ? )
open you workspace
Launch Maven Update
Should be good
Simpler fix:
Close Project
Open Project
Project > Clean
Run Maven Update
I was using Eclipse Mars and in my case, just close and reopen my IDE did the work.
Dont know, if you still have this problem, but here is the solution worked for me:
It appears that deleting the file org.eclipse.wst.validation.prefs in
the directory .metadata/.plugins/org.eclipse.core.runtime/.settings
(default settings for workspace) or .settings in each individual
project will cause the settings for validation to be reset to their
original settings. You can then use validation without getting error
messages and try resetting the options from there. However, I'm not
sure what combination of settings would cause the problem to reappear.
However, if it does, you can repeat the process.
got this from here: https://bugs.eclipse.org/bugs/show_bug.cgi?id=355012
in my case i didnt have the mentioned file in this folder, but i had a bunch of other org.eclipse.wst.* files. deleting them all did the trick for me.
The problem is not related to the .projects folder as mentioned in another answer.
The solution is to add a file called org.eclipse.wst.validation.prefs in the .settings folder. This will restore the eclipse validation node.
The content of the file, depending on your eclipse version, might look like this:
disabled=06target
eclipse.preferences.version=1
Another Solution is too simple , deleting .project file then clean the project and maven update will success surely
I think this is one error that could be caused by multiple different sources. I just had the same error however, and just figured out why. In my situation, I just tried to force update some code by deleting a few temporary files. Turned out I accidentally deleted that file as well. I thankfully had it under source control, so I pulled the file back and updated the project with Maven. I also made sure any other errors were fixed so that the project would clean / update successfully.
I'm not sure if this will solve your problem, but I hope it helps! Good luck!
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.
My computer suddenly shut down due to power failure, while I was working on an Android project using my Eclipse Indigo IDE.
Now, if I start Eclipse, only an empty message dialog (see screen shot) appears and Eclipse does not start. What can I do?
(I am using Ubuntu 12.04 LTS)
Mabe Some files found in the .metadata folder of your workspace are damaged, have you tried to launch it by specifying another workspace?
You can manually specify the workspace location on the command line, using the -data command-line argument.
If you don't want to loose a lot of time by trying to fix the problem, you can import your projects into the new workspace, reinstall the plugins that was installed before and everything will be ok. otherwise, you have to take a look on the .log file found in the .metadata folder of your old workspace, analyse the stacktrace and try to understand which plugin is corrupted and delete it manually, and this may take a lot of time, thats why i suggest you the first solution. About the .metadata folder, it is in ~old_workspace/.metadata.
check your filesystems. Maybe something got corrupted when power was lost.
Check my blog post When Eclipse Won't Start and Restoring a Corrupted Workspace in Eclipse
For me, .metadata files were damaged. Since eclipse was not opening at all, changing the workspace was not an option. I deleted following directories, and could start afresh!
.metadata
.buildpath
.project
Hope this helps you as well.
Please note that you will end up loosing all the project settings.
I know my reply is too late. Hope this helps another user.
My Ubuntu in the VMware was shutdown abnormally for some reason. When I logged back in Eclipse would not start. I fixed with the following steps:
removed .lock file in the .metadata folder in the workspace
started eclipse using command line with "-clean" argument
It started fine!!!
I tried to find the corrupted file by removing the files from ~/workspace/.metadata/ one by one until Eclipse could start.
The corrupted file was ~/workspace/.metadata/.plugins/org.eclipse.core.resources/.snap
Once the file was removed Eclipse started normally.
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...
