I have changed some image files in my assets folder and they are appearing correctly in the Package Explorer of Eclipse but when I run my game the new versions do not appear and the old versions are still being used. When I add a new file and try to use it in code I get a "Couldn't load file" error, even though it is appearing in the file hierarchy. It seems like my assets are stuck as what they were 6 hours ago all of a sudden. What could cause this?
EDIT: The only thing I can think of is that I added new dependencies to the build.gradle file, and I think that was around the time new resources stopped loading. Could that be connected?
Have you tried doing Project->Clean, followed by a Project->Build All?
Eclipse will most likely not recompile your project automatically, if you do not change the source and just swap out some resources. Thus, your old resource files still reside in the build folder (and in the path at run time).
Your new files only seem to be present in the source folder and are not used at run time.
You can try deleting the bin folder in the project and then rebuilding. This will definitely change it.
The above is not, a permanent fix.
The subfolder myproject/wp-content has dissapeared from the project explorer (of course the files are still there, I can see them on windows explorer).
All the other folders and files are still showing up.
I tried deleting the project files (.settings .buildpath .project) and deleting the project on eclipse and also deleting the index on .metadata/.plugins/org.eclipse.dltk.core.index.sql.h2
What else can I do?

[EDIT] I forgot to mention I've also tried to rebuild the project with the same results, and I've also checked explorer view filters in case something weird had happened but there are no filters set.
[EDIT 2] I deleted the Eclipse project files and the whole .metadata folder on the workspace and recreated the project. I had no problem at first, but it has happened again. I haven't touch any settings, just closed and reopened the project.
[EDIT 3] The less invasive fix by now seems to be a combination of deleting h2 database (.metadata/.plugins/org.eclipse.dltk.core.index.sql.h2 workspace folder) and deleting also the project without deleting its files which doesn't delete .build or .settings or .buildpath either, so it can be recreated without much hussle. I can avoid the problem by not closing the project (I can still close Eclipse without loosing the folder), but I still don't know what's causing it.
[EDIT 4] I updated Eclipse and plugins today to their latest versions (Now runnning Kepler 4.3.2) and the problem persists (even if I delete org.eclipse.dltk.core.index.sql.h2 and .settings, .buildpath, .project before importing the project's folder contents as a new project): I just close the project after eclipse finishes indexing it and when I reopen it wp-content doesn't show up any more (unless I force reindexing by deleting org.eclipse.dltk.core.index.sql.h2 again). I do believe this is WordPress related, since it only happens when indexing this particular WordPress deployment (maybe it's one of the plugins/theme files installed inside wp-content or something related to one of the xml files in the root folder, like sitemap.xml?).
For me this happened multiple times, on different project and different folders. Opening+closing or refreshing the project yield no success.
In my case, I have found out that this is related to the Working sets. It seems by default new subfolders and files of a project are not marked belonging to the set, so the project has a mix of old folders (included) and new folders (excluded).
There are two fixes I am aware of:
disable the working sets
Moreover, on large projects, having this mixed state working set made opening the folder structure (and other operations) very slow (3-5 seconds per level). Turning off the working set filter made it instantaneous.
edit the active working set and check the project's checkbox (which will check all subfolders).
This happens to me all the time. I'm on OSX and my projects are accessed from a mounted samba volume. I've found that if I:
open the project in eclipse
eject the samba volume
refresh the project (it will say it cant find it and ask if you want to delete
it... click no)
remount the samba volume
refresh the eclipse project
And the missing files/folders show up. If your folders are local, maybe just moving the project folder would do the same. Unfortunately, this happens very often, and seemingly more often for wordpress projects for some reason.
I'm working with a UI project (Dynamic Web Project) and my web folder keeps dissapearing too. I didn't knew what causes that.
The only thing I knew was how to reset my projet; deleting it from workpsace and reimporting it.
I know now what causes that but I have no answer on why it actually does it. I keep refreshing my workspace because I have some compressing that is done outside eclipse and for my workspace to update them I need to refresh... somehow, the freaking Close Project option is right under the Refresh option, without prompting... and this is when my folder dissapear; when I reopen it.
Try the Import Existing Project would be my guess!
Maybe that can help you find the how of it !
Hi i solve this problem by unchecking "Group by Namespaces" in the little triangle on the top-right of the php explorer.
Issue:
My app directory in my cake php application became invisible after some time. This is bad since all of my non-cakephp framework files reside therein!
My environment:
Macosx
Eclipse Kepler
WebServer: built in macosx in Library/WebServer/Documents which is symlinked to a dir in my home directory.
PHP plugin
What I tried first:
Deleted old project from UI ( retaining files on the file system )
cd'ed to root project directory and deleted eclipse artifacts like .settings, .project, etc
Recreated php project to find that the app directory is still missing!
What worked for me:
I renamed the directory from app to app_back using the terminal/linux command rn.
Eclipse immediate saw the new dir after a clean rebuild.
I renamed the dir back to app and performed another clean rebuild.
Et Voila
It seems that by upgrading Eclipse to last version (Luna), removing the project files (.settings, .classpath and .project) and creating a new project on a new workspace, I can close and reopen the project without having the folder missing from the project explorer.
It's not the solution I wanted (and don't need any more) but it's also a solution, so I'm posting it :-)
I have an existing SBT project which I'm primarily working on using Emacs with Ensime; I would like to keep it that way. However, I would also, occasionally, like to edit and refactor (and if possible, compile and run) the same project in Eclipse Scala IDE.
I don't seem to be able to go about doing that without the project folder being copied to a workspace. I've tried both [Import -> Existing Projects into Workspace] as well as [Import -> File System] to no avail—both seem to cause a copy to be made.
If it's something simple and obvious, I apologize; I'm quite a beginner with Eclipse. Also, I did ask Google, but couldn't find anything that is similar enough—usually it's just people moving away from one editor/IDE to Eclipse, so they don't care about the code being copied in the import process.
P.S. I tried opening the containing folder of the existing project as the workspace, but after that, the workspace is still empty.
P.P.S. One might ask, why not just make the Eclipse workspace the primary location of the project and then edit it with Emacs there, but that would mean changing my existing "standard" layout, or moving just one project out to a dedicated Eclipse workspace or smth. So I think it would be nice to just edit an existing folder with Eclipse without having to move or copy it.
OK, got it; it was easier than I'd thought: Just create a new (Scala) project with the path of the existing project (uncheck [Use default location]), and it seems to Just Work.
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 Eclipse with GAE broken and works strangely.
So I deleted Eclipse from Application folder, but there is garbage left. I re-downloaded fresh new eclipse, but it runs with old settings, and broken GAE structure remained.
How can I DELETE completely Eclipse from my Mac? (without any kind of settings/plugins/logs etc.)
Eclipse itself will be installed where you've unzipped the file you've downloaded. This directory contains Eclipse.app, configuration/, plugins/ and features/ (amongst others).
Your workspace/ directory (in your home directory by default) contains all your projects and various settings too, in workspace/.metadata/ (see dot files if you want to have a look). Deleting the workspace will delete your own project files of course, so you would need to make sure you have a way to restore them from a clean version (for example from a version control system if you're using one).
If you don't want to delete your entire workspace, it might be worth moving it away and then copying the projects back in, leaving the new workspace/.metadata/ clean, to see if this fixes your problem.
Add ~/Library/Caches/org.eclipse.platform.ide to the list
Im not sure if this is the right place for such kind of questions...But r u using any applications such as "app cleaner"?
if not try it... http://en.softonic.com/s/app-remover:mac
