Is there a way to force Eclipse to save project / workspace settings? I can't find a "save workspace" or "save project" command.
(I've never had a problem with this in Eclipse, but TI's Code Composer 4 is based on Eclipse and it sometimes crashes and doesn't retain the changes I made in project settings.)
The surest way to force such a save would be to switch workspace.
Switch to an empty workspace, and then switch back to your current workspace: every project settings should have been saved and restored.
Note: the bug 27821 ([Workbench] saving state and preferences) is a duplicate of:
bug 2369 ([Workbench] Would like to be able to save workspace without exiting), which is opened since... 2001!
So even the "switching workspace" trick might not be enough to save every settings, but that is a start.
Edit September 2011:
Aaron Digulla add in the comments he has added a plugin 'saveui' (bug 337593, which duplicates bug 2369), and which could be a good solution to save your workspace state (without having to close your Eclipse or switch your workspace).
To use this plugin, download the code, open the archive, copy the "dropins" folder into your "eclipse" folder (possibly merging with the existing dropins folder), close Eclipse, and re-open Eclipse. You should see a small lock-like icon in the toolbar, just below the menus. Clicking this icon is supposed to save the workspace.
The place where is a workspace - workbranch is in
Workspace\.metadata\.plugins\org.eclipse.e4.workbench\
You can use wakeup() method to force save workspace
Job[] jobs = WorkbenchJob.getJobManager().find("WorkbenchAuto-Save Job");
Job workspaceJob = Arrays.asList(jobs).get(0);
workspaceJob.wakeUp();

I just installed Eclipse on a computer and it has been working fine for the past few days. However it suddenly stopped working this morning.
When I double click a file in the File Explorer to open it, nothing happens - a new tab is opened, but the tab has no title, just a button to close the tab. The "contents" of the tab is just a light blue screen, with no text.
I have tried the following procedures, with no success:
Right click > Open with > various Eclipse editor
Reset perspective (I am in Java EE perspective)
Change perspective to Java
Opening different file formats (.java, .properties, .xml, etc)
F3 and Ctrl-Shift-T
Creating a new project and opening a file from there
Restarting, cleaning workspace
When I open a different workspace, the files open as usual, but I still want to use my old workspace.
I am using Eclipse JEE Oxygen.
Doing a re-install fixed the problem.
Try to create a new workspace and put all your projects there from the old one.
If it does not work, it's likely that there is an error in one of the projects, try to find it, delete the project from the new workspace 1 and try to open the file, repeat it until the file opens, if you make a mistake in 1 of the projects, then you can create new classes. and copy there codes from the old ones.
P. S. If nothing works, you can download INTELIJ and open your workspace there (generally Intelij is more comfortable than Eclipse in my opinion)
Right now I'm having this issue in Eclipse where I have an XML file open that's really big in which it almost crashes Eclipse. However this file being opened is saved in my window history, therefore I restart eclipse, it tries to open this massive file again. How do I clear the opened window history in eclipse?
I would prefer not having to clear my workspace entirely as I have mylyn data I want to keep. I've tried using Eclipse clean but this doesn't seem to do anything related to opened windows.
Your workbench information are saved in this file in your workspace:
.metadata/.plugins/org.eclipse.ui.workbench/workbench.xml
or depending on your eclipse version:
.metadata/.plugins/org.eclipse.e4.workbench/workbench.xmi
You can delete it and eclipse will recreate the file, you can also try to edit it, but it's a big file and may be hard... Deleting this file all workbench related settings are lost but your projects stays intact.
Go to Preferences and search for 'workspace'. You will see the list of workspaces that you can delete.
Some alternatives:
Move or rename the offensive file so that eclipse is unable to open it.
File->Switch Workspace->Other to load a new workspace copying your workbench layout.
Just some thoughts, my experience is closing a file and then the program means that the program will not attempt to open the file once launched again.
I don't know what went wrong, because this was working before, but all of the sudden I don't have any files in my eclipse package explorer.
The workspace path appears to be correct and the file permissions are correct.
Can anyone think of what's wrong?
Refresh the project
If that does not work, close and open the project again.
I had the same problem (Probably caused when I cancelled a copying to my Dropbox folder)
I only needed to click File → Import → General → Existing Projects into Workspace and select the missing projects in the window that appeared.
Workaround
Create a blank workspace
Navigate to (File > Switch to workplace > Other)
Clik Browse > Make new folder
Click Ok in browse window
Click ok in create workspace window
Import your existing project into the new workspace
Navigate to File > Import
Click General > Existing project into workspace
Click Next
Browse and select your previous project
Click on Finish
Congrats! Now you can see your project in the package explorer by importing it.
Project Explorer -> click on "View Menu"
-> Top Level Elements -> Click on "Projects"
Don't know what causes the problem, but found a way to get the files back into the package explorer.
If you go into the path of your workspace and find your projects, then you can pack them all into a zip archive file, and from this zip archive file you can import your projects again by using the File → Import → General → Existing Projects into Workspace menu.
I don't know what causes the problem, but in my case I think it have something to do with me having my workspace in a dropbox folder.
ps. I don't know if you actually can take more than one project into one zip file and make it work, I have only tried it with one project pr. ZIP-file, but it shouldn't matter.
In 2020 on OSX I just went to Project -> Refresh and wham! my files appeared.
I had started the wrong installation of eclipse. When I started the correct installation my code showed up fine. I have both C++ and Java EE installs.
Just refresh all the projects, you able to see all missed files after you import from a workspace.
1) Make sure that you use the right workspace.
2) Choose your "workspace"-Folder "/YourWorkspace",
NOT your project folder"/YourWorkspace/yourProject"
Alternatively delete your project from your
"YourWorkspace>/.metadata/.plugins/org.eclipse.core.resources/.projects/PROJECTNAME/.location"
and restart.
Hope this helps
I had the same problem. I was not able to see the imported files in Eclipse, but there were visible in File Explorer.
After a while, I noticed that all the files were imported. They had their names changed from myFile.class to ._myFile.class.
I deleted all the imported files from my workspace by using File Explorer.
By using the same File Explorer, I copy-pasted the folders/files in the workspace.
Then in Eclipse, I refreshed the project (F5 or click-right -> Refresh or File -> Refresh)
I faced the same issue and the reason was that I choose double click on Eclipse Icon, then I need to choose Work Space.
Here I made mistake. You do not need to select folder in which has all your project files
e.g //Desktop//User//Selenium//S1A//all files related to project
In that case for workspace you choose //Desktop//User//Selenium, import your project by clicking Import for eclipse 2020 and choosing File path //Desktop//User//Selenium//S1A.
may be a rare case like in mine, but if you played with colors this may be an issue and especially, if you changed theming and did not restart, which may correct some problematic visual stuff.
Import>Existing Projects into Workspace> Select root directory> Select the folder
The solution that helped me:
create a new folder (=Java-Package) with a new name. I used the System-Filemanager.
copy the disappearing files to the new folder (=Java-Package).
correct the links (JavaCommand 'import') to the new folder.
delete the old files and the old folder.
As the problem happened in my case:
I am using Eclipse IDE 2021-12 (4.22.0) for my Java project.
After importing an existing Project into Workspace all was fine.
While building the project, same files disappeared from the 'Project Explorer'-Tree.
These files still do exist as the System-File-Explorer shows. So no file got deleted. But no more listed.
After Refresh (F5) most of the files got listed again in the 'Project Explorer'-Tree.
Without doing anything an Eclipse background process let files again disappear from the 'Project Explorer' - Tree. Compilation of the project leads to missing files.
Sometimes 3 files disappeared. Some seconds later more files disappeared. Sometimes it leads to an empty Java-Package.
This disappearance of some files happened without any input from me. It was done by the Eclipse background process. It felt like watching a movie.
What does not help in my case: Restarting of eclipse, Close and Open the project, editing the files.
In my case, the problem was due to an unwanted nested project in a subfolder. There is a pre-set filter that hides folders in that case.
For some reasons, the sub project was not shown in Project Explorer.
My solution :
delete the project (without deleting project contents on disk)
import existing projects into workspace, and do not import nested project.
You might have filtered the resource out of the project.
Select the project, right click, choose properties.
Under Resource, choose "Resource filters" - check that the name of the folder or the files was not filtered in the list under "Exclude all" (if there is one)
I imported an Eclipse project into workspace and after some time I deleted it in Eclipse (from project explorer but not from workspace). Now, I want to reopen it, or import it again, but I cannot import it because such a project already exists in the workspace and when I try to open it, in tab Project -> Open Project, it is disabled. Of course, I can delete the project from workspace and import it again, but this is not what I want. So the question is: how can I open the project, which is in Eclipse's workspace, but has been deleted from the Eclipse's project explorer?
This is exactly what I just ran into. The 'Finish' button is greyed out, as is the check box and project name in the project window. If you try to check that check box the project will not be greyed now, but it won't check. Refresh does nothing.
The trick (or is it a bug) is to uncheck 'copy projects into workspace' hit the refresh button and it will now be checked and you can hit the finish button. Project will now once again be available in the Package Explorer.
(I'm using Eclipse 3.8 and ADT 21.0.1)
These Steps You Have to Follow
Click File menu
In file menu click Import
A window is open Now click General Folder
Now click Existing project into workspace
Then click the select from root directory
Now import project which you want......
You have to choose the project in the workspace, not the zip file with your project. Your project is still in your workspace, and because Eclipse wants to copy the project from the zip file you chose (look at the checked check box "Copy projects into workspace"), you get that warning.
Just select "Select root directory" and choose your workspace as your root directory and choose the project you want to reimport (and make sure, that the checkbox "Copy projects into workspace" is not checked).
Go to “%ECLIPSE_HOME%\configuration.settings” and delete the workspace listed at the key RECENT_WORKSPACES
Restart Eclipse, go to File>Switch Workspace>Other… and select your workspace dir again
Now I could create new projects as always
One simple trick is to delete the project from your work-space directory manually and than try to import project again. That's it...
I've experienced this same problem. It was a deleted workspace which I re-imported. When I tried to work with junit tests in the directory, it said that parts of if were not in the "project" In order to fix this, I had to check the "SEARCH FOR NESTED PROJECTS" and that corrected the issue.
I know that this is a really old question, possibly the solution was not available back then, but on my system (Eclipse Photon 4.8.0) it works like this:
File menu
Open Projects from File System...
Here you can give Eclipse a path to a directory (in this case your own, currently used workspace directory) where it will search for possible projects, list them and let you choose which one to import into the workspace. It will show already imported (aka. existing inside Eclipse) projects grayed out and unselectable, but has an option to hide these as well.
After selecting the project you'd like to import just click the Finish button and voila.
Make sure that your project is included in current workspace, then you have to see the project under "Project Explorer".
Note: you can view this from: Window->Show View->Project Explorer.
If you are facing this:
Some projects cannot be imported because they already exist in the workspace --> "Finish" button is grayed --> hence, no way to open the project(s)
Solution:
Go to File -> Open File...
Choose any one file of your project, and the entire project folder will open in your present workspace.
Where can I change the default workspace in Eclipse?
If you mean "change workspace" go to File -> Switch Workspace
I took this question to mean how can you change the Default workspace so that when Eclipse boots up the workspace you want is automatically loaded:
Go under preferences then type "workspace" in the search box provided to filter the list. Alternatively you can go to General>Startup and Shutdown>Workspaces.
There you can set a flag to make Eclipse prompt you to select a workspace at startup by checking the "Prompt for workspace at startup" checkbox.
You can set the number of previous workspaces to remember also. Finally there is a list of recent workspaces. If you just remove all but the one you want Eclipse will automatically startup with that workspace.
Go to eclipse\configuration\
Open the file "config.ini"
Modify the line
osgi.instance.area.default="F:/Workspace/Java"
where "F:/Workspace/Java" should be your default workspace!
If you are talking about changing the working directory for a java program that you launch from within eclipse, then there's a space for that in the run configuration.
If you go to Run menu and select "Run Configurations..." then select your run configuration, then on the "Arguments" tab for a Java Application there is a place for you to edit the "Working directory". This alters the current directory that will be used for launching the java program.
See related question Default eclipse working directory if this is what you are meaning.
Whatever Frank has suggested to change in config.ini is correct. In case, if that didn't help, you need to remove path from recent workspace as below.
Go to eclipse\configuration\org.eclipse.ui.ide.prefs\
Open the file "org.eclipse.ui.ide.prefs"
Remove the first path in RECENT_WORKSPACES.
MAX_RECENT_WORKSPACES=5
RECENT_WORKSPACES=/Users/wrokspace1\n/Users/wrokspace2\n/Users/wrokspace3\n/Users/wrokspace4
RECENT_WORKSPACES_PROTOCOL=3
SHOW_WORKSPACE_SELECTION_DIALOG=false
eclipse.preferences.version=1
File > Switch workspace > add the workspace you like > Eclipse will restart using the workspace you wanted.
If you mean to change the directory in which the program execution will occur, go to "Run configurations" in the Run tab.
Then select your project and go to the "Arguments" tab, you can change the directory there. By default it is the root directory of your project.
Open a command prompt.
Change to the eclipse home directory and type "eclipse -clean"
e.g.
C:/eclipse>eclipse -clean
This will ask for the workspace selection. It will also force to set it as the default workspace.
Then, go to eclipsehome-->configuration-->settings folder.
open org.eclipse.ui.de.prefs in a notepad.
set this property to true from false.
SHOW_WORKSPACE_SELECTION_DIALOG=true
You will be asked for a workspace selection everytime.
If you want to change recent workspace manually in a configurationfile
org.eclipse.ui.ide.prefs exists in
eclipse > configuration > .settings > org.eclipse.ui.ide.prefs
open this file in an editor find RECENT_WORKSPACES in line #2 and in this line you can see recent workspaces and can change or even remove them.
In Eclipse, go to File -> Switch Workspace, choose or create a new workspace.
This is the only answer you got first when you search for default workspace, but any solution is not solved my problem, So I follow this step for a default workspace:
First copy shortcut icon for your eclipse.
Right click and go to properties,
add your workspace path with -data attribute,
In Target:
D:\eclipse_path\eclipse.exe -clean -data D:\workspace_path\workspace
For using the same shortcuts and preference into this workspace,
Export general --> preference from your working eclipse, it will generate one .epf file.
So, just import .epf file into your new workspace, and you are done.
If you want to create a new workspace - simply enter a new path in the textfield at the "select workspace" dialog. Eclipse will create a new workspace at that location and switch to it.
On Ubuntu I went to
~/.eclipse/org.eclipse.platform_4.3.0_1473617060_linux_gtk_x86_64/configuration/config.ini
and added this line at the bottom
osgi.instance.area.default=#user.home/workspace
and changed workspace to the dir path from my home to where I put my workspace.
I combined #Frank answer with #Ronan Quillevere's comment
My kepler eclipse went into not responding at boot (shortly after installing GAE support) which I traced to a corrupt workspace. I fixed this by closing kepler, renaming the workspace directory (in use) so kepler starts normally without a workspace, then used file >> switch workspace to generate new workspace. Then started populating that with my old projects that I still needed.
You can check the option that shows up when you start eclipse. Please see the figure below
