I missed my workspace in which I was working.
Any one have idea about how to get list of all workspace of ecliplse.
when we start eclipse it show just 5-6 workspace only.
Change this preference - 'Preferences > General > Startup and Shutdown > Workspaces > Number of recent workspaces to remember'
I know its a silly question but i am stuck into it from 2 hours..Can any body tell me how should i enable the dialog which opens at the time we start eclipse and we choose workspace location from there.
See I want this window to be displayed first when eclipse starts
By mistake I have checked "Use this as the default and do not ask again".
Please guide me how to show up this dialog again
You can find it here :
Menu: Window -> Preferences -> General -> Startup and Shutdown -> Workspaces -> Prompt for workspace on startup
Eclipse preferences has a lot of options. You can search for specific options by typing in the filter text box at the top of the preferences dialog.
If you type in 'startup' for instance the list will be much shorter.
window > preferences > general > startup and shutdown > workspaces
then check 'Prompt for workspace on startup'
If your workspace is corrupted and Eclipse doesn't startup with your currently pre-selected workspace, you may edit SHOW_WORKSPACE_SELECTION_DIALOG=false to SHOW_WORKSPACE_SELECTION_DIALOG=true
which is located in file
C:\PathToEclipse\eclipse\configuration\.settings\org.eclipse.ui.ide.prefs
before you start the IDE.
I noticed that after installing cdt, Eclipse always loads the default workspace. The workspace listed in the config.ini in osgi.instance.area.default. Eclipse does not ask which workspace to open regardless if Prompt for workspace on startup is set or not.
How do I force Eclipse to ask which workspace to load on startup?
It works for me if I tick the box Prompt for workspace on startup, which you can find in
Window → Preferences → General → Startup and Shutdown → Workspaces.
I had the same problem with indigo on linux 3.0 X86_64:
After runnning eclipse -clean everything went back to normal.
Thanks to some comment on the eclipse issue:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=134412
Inside the configuration/.settings folder of your Eclipse installation, there is a file called org.eclipse.ui.ide.prefs. Open this file in a text editor and change the property SHOW_WORKSPACE_SELECTION_DIALOG from false to true.
Tested with Eclipse 3.7 on Windows.
Using Eclipse Indigo this is how I did it:
Window → Preferences → Startup and Shutdown → Workspaces
Check the box at the top of the window that says "Prompt for workspace on startup"
The “Prompt for workspace at startup” checkbox did not working.
You can setting default workspace, Look for the folder named “configuration” in the Eclipse installation directory, and open up the “config.ini” file.
You’ll edit the "osgi.instance.area.default" to supply your desired default workspace.
Version: Eclipse CIndigo Service Release 2
File > Switch Workspace > Other...
In the textbox, write the path in the Workspace or Browse
It automatically sets the default Workspace during exit.
I followed the thread and tired all things but didn't work. Finally I saw that my eclipse shortcut target is like below
C:\Eclipse_3.6\eclipse\eclipse.exe -clean -data "C:\workplace" ...
I simply removed -data option and it worked. Now I got popup to choose workspace at startup.
cheers.
I had the same issue (in Eclipse Juno), but I just wanted to change the default workspace to the one I'm using
There's a setting in ECLIPSE_DIRECTORY/configuration/config.ini that is causing a specific workspace to be loaded without prompting for a workspace. If you just want to change the default workspace, you can just modify the value or add it if it doesn't exist:
osgi.instance.area.default=#user.home/some_workspace
or
osgi.instance.area.default=/some/absolute/path/some_workspace
Starting eclipse with eclipse -clean did wonders for me.
I can confirm that I am having the same issue. I am also using Eclipse classic with CDT. The funny thing is that it only started happening earlier this evening. Before then, I was always prompted for the workspace. Checking Prompt for workspace on startup has no effect. I am not launching eclipse using a startup script, so the -data flag is not set on launch. I have removed the line osgi.instance.area.default from the configuration/config.ini file, but that had no effect.
A few strange quirks that are incidental to this problem: If I delete the workspace workspace it creates it again upon launch. However, when I switch to one of my "real" workspaces I notice that the workspace workspace is not listed as an option to be switched to.
As would be expected, reinstalling Eclipse resolves the issue. But it would be nicer to find a way to fix the problem without resorting to that.
Under Aptana 3.2.2, in \configuration\.settings\org.eclipse.ui.ide.prefs, edit:
RECENT_WORKSPACES=I\:\\PDT\\workspace
It will check the recent workspace, so just set it to what you want. I do it for running off an external drive.
Editing the config.ini file with
osgi.instance.area.default=\D:\\Projects\\Eclipse Workspace\\
worked for me.
Sometimes you need to pay attention to howw Eclipse is launched. I ever pinned Eclipse by rigk-click on the excutable and pinning it to taskbar. In this way, the Eclipse is launched to use settings under c:\User\public\public Documents\eclipse" which is not very desirable.
However, if you pin it by creating a short-cut, then it will launch to use settings in the folder of Eclipse installation. Then everything makes much more sense.
I'd recommend you to create a shortcut to eclipse.exe with the -data command line option. This way you can create a separate shortcut to each workspace you use, and avoid unnecessary dialogs and mouse clicks.
Windows: Just create an Eclipse shortcut on your desktop, then right-click to open Properties and under Shortcut set something like this as Target: C:\eclipse\eclipse.exe -data C:\Path\to\your\workspace1. This will launch Eclipse and automatically open workspace1.
Repeat the steps for all the workspaces you use often.
I resolved the problem by adding the -showLocation flag to eclipse.ini.
I first tried the -clean option, but that didn't solve the problem. Then I added the -data option with the correct path to the workspace, which worked.
If your Eclipse is auto-closing at startup you can
Open the properties of your shortcut and add -clean at the end of the path,
Or, in a command prompt, run C:\PATH_TO_YOUR_ECLIPSE\eclipse -clean like mentioned in the comments and other answers
I had the same problem on my Eclipse, and calling eclipse -clean did not solve the problem.
In the end I figured out that within the installation folder of Eclipse there is a script called eclipse. This script does some setting of environment variables and then calls eclipse.bin. The call for eclipse.bin contained the this command-line switch:
-data ~/.eclipse
When I removed that switch from start-up script, I got the workspace selection as expected.
Go to Window → Preferences → General → Startup and Shutdown → Workspaces (or Eclipse → Preferences → ... on macOS)
Check the checkbox Prompt for workspace on startup
Then at startup Eclipse will ask for workspace selection.
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
I would like Eclipse to automatically save every time I edit a file, in much the same way that it builds automatically. Because I've been using IntelliJ for the last year (which saves automatically by default), I keep having the following problem:
Make some changes in Eclipse
Forget to press save
Run the build, unit tests, and notice some strange behaviour
(Some time later....) realize that the unexpected behaviour occurred because I forgot to save the changes
Is there any way I can make Eclipse save automatically?
Eclipse Neon (4.6)
Window > Preferences
General > Editors > Autosave > check Enable autosave for dirty editors > choose the value for autosave interval (in seconds)
Details in M7:
Auto-save of dirty editors is now available in Eclipse. The autosave option is disabled by default. A new autosave preference page (Preferences > General > Editors > Autosave) is available and allows to enable/disable the autosave and change the interval of autosave. The countdown is reset on keyboard activity, mouse click, or when a popup is displayed (e.g. content assist, preference page, ...).
You can go here and check the box Save automatically before build
Windows > Preferences > General -> Workspace
First, try Window -> Preferences -> General -> Workspace. There you can check "Save automatically before build" and "Build automatically."
If that does not work,
PLEASE TRY
Preferences -> Run/Debug -> Launching -> "Save dirty editors before
launching"
You can do it with the saveDirtyEditor plugin as referenced in this question/answer. There is no non-plugin way of doing it.
I wrote an Eclipse plugin for this called smartsave. It's available in the Eclipse Market Place.
It saves your files at a specified interval and you can even tune it to prevent saving if errors, or warnings, are present in the preferences dialog.
In Helios this can be done by going to preferences and setting:
Run/Debug > Launching > Save required dirty editors before launching
For Eclipse Mars 2, the settings are below Window > Preferences > General > Workspace. These settings are in minutes and not in seconds.
You could go to Windows > Preferences > Autosave and set the auto intervals to 1.
