eclipse -restore missing projects - eclipse

For some unknown reason the projects that I created in a workspace are no longer listed in the package explorer tab. The actual files of the programs still exist on the flash drive which was the designated workspace. How do I correct this problem so that I can access the projects in this workspace?

Are you in a different workspace? Try File > Switch Workspace or if you are in the right workspace already, you could try File > Import > General > Existing Projects into Workspace and re-import the projects.

Create new project on the menu, then select the button "Create project from existing source" and select your project directory on disk.

If you are working with Android projects, the straight import does not work. The fastest way I've found to deal with this issue is to move (not copy) the projects to a different location, then import them back into the workspace, making sure copying the files into the original workspace.
At this time, the Android eclipse plugin has a bug in it which will rename your projects to the package names, rather than using the "friendly" names you intended for the projects. Since eclipse quite often seems to drop projects in this way, this can lead to a great deal of frustration. If this bug is fixed, or you know of a workaround, I would appreciate hearing about it.

I had a case where my project disappeared from the workspace and when I tried to import the existing project into workspace, Eclipse reported the project was already in the workspace! So I simply created a new project with the same name/location as the folder in which the project was located. This brought the project back to life in my worskpace. This worked in Kepler version of Eclipse.

I found a way to resolve this issue without creating a new project.
My projects disappeared from the Package Explorer view when I was in the Java EE perspective. When I switched to the Java perspective, they reappeared in Package Explorer.
Version: Mars.2 Release (4.5.2)
Build id: 20160218-0600
Not sure what caused this issue out of the blue and how long this solution will hold.

A simple solution that requires deleting the affected projects from your workspace, then importing them again:
Delete the affected projects from your workspace (do not delete from disk)
Open the files. File >> Open Project from File System >> Select location of files >> Select projects to open.
After you import them, it should work.

Try a refresh (F5) of the workspace.

Why do projects that I add to my 'workspace' folder don't show up? [ECLIPSE]

I am using Eclipse Indigo, and after having successfully extracted my project folder into my Eclipse workspace, it does not show up in the package explorer. I tried refreshing eclipse and restarting it, to no avail. I am 100% certain my eclipse is using the right directory and the project is in it.
What could be the problem? Thank you.
EDIT: "import projects into workspace" worked for me, but why was that necessary?
Files in the directory are not automatically picked up by the package explorer. You need to import them.
Try using the File > import, then choose
Existing Projects into workspace.
There is a checkbox that says "Copy projects into workspace" which copies it to your workspace if it happens to be in a different folder. If you start with your files in another folder, you'll see how it's copied and set up with configuration files in your workspace directory.
To answer the question, "why is it necessary to import?" you have to realize that the Eclipse workspace is just a logical container for projects, not necessarily the physical container for them.
Also realize that a directory of project-related files does not make an Eclipse Project; Eclipse must be given or generate it's own set of configuration in order to understand a project (minimally, for Java projects, .project and .classpath). Without those, Eclipse has no idea what to do with an arbitrary folder that you call a "project." That's what the Import or Create Project wizards are doing under the covers, generating those config files.

Eclipse is not showing any projects from my workspace folder even the projects are there?

We are using subclips as a SVN client for our Eclipse and I have successfully checked-out the list of projects to 'C:\workspace\myprojects' folder then I have opened the eclipse and given the workspace location as 'C:\workspace\myprojects' but it's not showing any projects even there are projects, Why?
So I have imported all the projects one by one through the eclipse feature and now i can able to see the projects but my question why should i need to import even i have given the eclipse workspace folder as 'C:\workspace\myprojects'?
NOTE: But the sampe scenario is working fine in others machine, i.e they no need to import all the projects one by one when they have given the Eclipse workspace folder as 'C:\workspace\myprojects'.

Eclipse uses the metadata to determine which projects are in the workspace. So you have to import the projects into the workspace even though they already reside in the same directory in the filesystem. Just call File / Import / Existing Projects from the filesystem and select the projects that are already there. It's a pain, but it works.
Just because you have a project inside the workspace directory doesn't mean Eclipse opens it or even sees it automatically. You must use File - Import - General - Import existing project into workspace to have your project in Eclipse.
Actually some of eclipse configuration file was deleted. hence it was not able to show.
finally after reverting the it I can able to see all the projects.

Can't Open Existing Project in Eclipse

I'm trying to open an existing Android project in Eclipse. I've gone to File > Import > General > Existing Project (or something like that). I've chosen the file project folder. But every time I try to open the folder, all I get is an error.
Some projects cannot be imported because they already exist in the workspace*
Is there any other way of opening my project?
You cannot import a project with a name already present in your current Eclipse workspace.
The surest way to work around that is to switch workspace (menu File / Switch workspace), and create a new workspace (in which you will be able to import that project).
A more complex solution would be to try and rename an existing project in your current workspace.
Check other causes in:
"Some projects cannot be imported because they already exist in the workspace error in Eclipse"
"Erased project from Project Explorer and cannot re-import it"
"How to import a project which you just deleted in eclipse"
I faced the same issue, But it is as designed. When people close the project, It simply makes the project unavailable in the eclipse project view. This is why people thinks that it has been completely removed from the view.
So All you have to do is to go to
Window -> Show view -> Project Explorer
Now you will see your project in the Project Explorer sidebar with a different closed folder Icon as shown in this image.
Once you right click and open project you will see the magic you are looking for.
I had the same problem and I solved it finally.
So, lets say you want to open "TEST" project on eclipse. And you project is in this path: C:\Users\Sabina Comp\Desktop then your workspace should be C:\Users\Sabina Comp\Desktop not C:\Users\Sabina Comp\Desktop\TEST.
You can switch workspace by going to File->Switch workspace->other
I hope it will help you!
Just delete the .project file and try to open the project again in Eclipse File Explorer :)
I faced the same problem. Maybe the cause of your problem is as simple as mine.
I closed (not delete) my project in the Java Browsing view. Unlike the Java view, the project becomes invisible in the Java Browsing view. So I thought I deleted the project. But turns out my project is still in use when I try to import it.
So I went to Java Browsing view and right click the blank space in the Projects panel, click Open Project and the project is back!
Right click on a working set --> properties.
You should be able to see all the projects that are available in your workspace. Select it.
Next all the projects should be listed in your working set.
Here's what worked for me:
Right click on the project > Source > Format
I guess you want to create a copy of the existing project and make changes to the new one. Or you have got a project whose name matches the name of the existing project and you want to import the new project as well.
In the first case , you just need to simply copy(Ctrl+C) and paste(Ctrl+P) in the package or project explorer in the eclipse and it will ask you for a new project name -- rather than copying the project folder in the windows explorer and renaming the project folder name.
If you have copied the project in windows explorer and tried importing the project in eclipse you will get the above error Or if u have got a project whose name matches the name of the existing project in eclipse also you will get the above error.
Solution for both -- is to delete the .project , .classpath and .settings files and import the project. It will successfully import if u have changed the folder name.
Tip: If its a maven project , you can import it as a Java Project and then RightClick on the project and Configure->Convert To maven project.
In my case, problem was -
I deleted the code directory from its location.
And at the same time I closed Eclipse.
So when I reopened Eclipse, it searched for project and couldnt get it.
I restored the code directory at original place.
Opened Eclipse.
When tried to import project again I found it in closed condition.
I opened it and it started working properly.

Eclipse projects not showing up after placing project files in workspace/projects

I've searched for 2 days and can't find anything. I find things that are close, but not what I need.
I got a new computer recently and copied all of my projects over to my new computer.
I opened Eclipse and generated a workspace, which I then closed out of Eclipse and copied my projects into the workspace/projects folder.
I reopen Eclipse and my projects do not show up at all in the package explorer.
I know that I have the correct folders in the correct directory.
The closest thread I found to this is: Eclipse - Import an existing project?
but even that didn't help, my projects already meet that...
I have tried refreshing, reopening, fooling with working sets, etc...
Just because you have a project inside the workspace directory doesn't mean Eclipse opens it or even sees it automatically. You must use File - Import - General - Import existing project into workspace to have your project in Eclipse.
For Juno: (With Source in E:\workspace and destination in C:\workspace)
Copy project directory in its entirety to the workspace directory.
(e.g. Copy E:\workspace\HelloWorld C:\workspace\helloWorld)
Start Eclipse.
Perform: File --> Import
Select: General -- > "Existing Project into Workspace"
"Next >"
Check "Select root Directory"
Select with "Browse Button"
Select "C:\workspace"
A list of existing projects will appear. Just check the ones that are in Bold (To Be Imported) then press the "Finish" button.
Review the Package Explorer and your copied projects should now be there.
This problems comes while .metadata of current workspace has been corrupted due to shut down Eclipse Unexpectedly. So if you face this problem just do the following steps:
Create a new workspace.
Import your existing projects to your new workspace.
you made it!
I had the same problem over and over again the solution that a have found works for now
Close Eclipse.
go to workspace.metadata.plugins
remove org.eclipse.core.resources
Start Eclipse
Do File->Import
General->Existing Projects into Workspace and import all the project from the workspace
Netbeans allows you to do a simple filecopy.
As you know, Eclipse doesn't work like that. You must explicitly "import" files and projects.
If you do import, and if there are no problems, then they should show up.
I'd consider:
a) making a backup of your existing workspace
b) deleting and reinstalling Eclipse
c) Trying another "test import"
You put them in the workspace/projects folder. You should put them directly in the workspace folder and then do an Import Existing Projects into workspace.
in Eclips the Package Explorer
Right click on any viewable project and select Show in -> Project Explorer
Package Explorer -> Right click -> Show in ->Project Explorer
you should be able to see all the imported projects in your Eclipse workspace
Even I had also observed the similar problem. I had closed my eclipse project because of some reason and on restart some of my file added were not visible in explorer even though corresponding file were existing.
Following solution worked for me:
Select whole workspace (Ctrl+A) ==> Righ click and press Refresh.
Or you could try:
Go to File -> Switch Workspace
Select your workspace (if shown)
As I had imported my project from a "git clone", I had to select File->Import-> Git->Project from git -> Existing local repository
Here's a specific problem I ran into when downloading a project from the internet.
Make sure you unzip correctly if it's zipped, you can sometimes get an extra level.
Make sure you place the project in the project file, not directly in workspace.
See if .project and .classpath have been renamed to _project and _classpath. You can't rename them directly so open a text document called .classpath and paste _classpath 's contents in there, saving as all files, not a .txt. _classpath can be opened with notepad.
Import the project from the file workspace. It will look for a folder called projects, your's should be inside it.
Hope this helps :)
The following worked for me.
Create a new project in eclipse.
After creating a new project in
eclipse, right click and select import.
General Import > File System
Select all the folders under your project except the root one. Click
finish.
This would create the required meta data and other internal eclipse project file system which will display your project's files.
You can also import the project directly as a file system. Follow the above steps if you are unable to import it directly.
Hi i also come across same problem, i try many options ,but finally the most easy way is,click of down arrow present inside ProjectExplorer-> customize View->filter-> unchecked close project.
And will able to see all closed projects.
I have tried many of the option suggested but at last importing project in new workspace solved my problem.
I think there is some problem in metadata files in old workspace.
I just wish to add one important detail to the answers above. And it is that even if you import the projects from your chosen root directory they may not appear in bold so you won't be able to select them. The reason for this may be that the metadata of the projects is corrupted. If you do encounter this problem then the easiest and quickest way to fix it is to rid yourself of the workspace-folder and create a new one and copy+paste your projects (do it before you erase the old workspace) folders to this new workspace. Then, in your new worskapce, import the projects as the previous posts have explained.
Yeah.... i kinda see what you need. I just came across same problem.
Here is exactly what i did. Now, bear in mind, this some low level knowledge, since i'm just starting. I made my life complicated, so i needed solution. I kinda found it on my own, using different directions from above answers.
I switched from win 10 on HDD to linux on SSD, so i needed my few of .class and .java imported into new workspace.
First i made a mistake, not using export option on windows and i just simply copied all of files from src and bin folders on win 10 to src and bin folders on linux. Of course workspace did not see those files.
Solution was found in IMPORT tool (which i should have used right away).
I put all of files in src folder into zipp file, and moved this file to some arbitrary folder (Home folder in my case).
Go back to src folder and delete all of .java files (you won't be needing them anymore).
Then i opened my empty project and selected import from File menu in Eclipse.
In import window, under option General (first one) select Import Archive.
Now simply find your zip file, and Voila! All is where it should be.
Problem: After creating a PyDev Project, the project does not show up in "PyDev Package Explorer" ;(
Solution: This is what I do to see them all in "Project Explorer":
I am using Eclipse IDE 2019-12
click on "Resource" icon at the top right corner
Now you shall see all projects show up in "Project Explorer".
Tricky note: now if you click on "PyDev" icon, you will see less projects show up in "PyDev Package Explorer" Magic?
What I did wrong about it, I used "import" - > "Projects from Folder or Archive" because I thought it would be the same thing. You have to use "Existing Projects into Workspace". Maybe this helps someone.
I experienced the same issues and I just click on Window -> Show view -> then Project explorer.
Then I got my project that was inside my eclipse workspace.

How do I reinstall Eclipse without losing my projects and plugins?

My Eclipse recently broke completely and I have upgraded to Galileo. I have created a fresh workspace (say foo/workspace) and created a trivial project. I have then copied an old project from (bar/workspace/myproject) to foo/workspace/myproject. It is mavenised and has a pom.xml. How do I tell Eclipse to build it (it does not seem to recognise it is mavenised). Do I have to install the maven plugin?
In general what is the smoothest way to reinstall Eclipse (i.e. what else do I need to think about?)
I never create or checkout a project directly under the Workspace but rather use something like ~/Projects for all my projects. This allows me to remain IDE independent. Actually, I never use any IDE to create a project.
I share my workspace location across several Eclipse install (specified at startup or using -data). If anything goes wrong, I don't mind deleting and loosing my workspace, it doesn't contain anything really important anyway.
Use the m2eclipse Eclipse plugin to Import > Maven Projects into Eclipse. Another option is to use the maven eclipse plugin to generate the .project and .classpath from the command line and then to Import > Existing Projects into Workspace from Eclipse.
It is better to reference directly your old workspace when starting your new eclipse installation: see this eclipse.ini
-data
c:/a/path/to/your/old/workspace
That way, you get back all your projects.
You can install the m2eclipse maven plugin by adding its update site to the list of sites examined by the eclipse p2 provisioning mechanism
http://m2eclipse.sonatype.org/update/
If the metadata associated with your workspace is messed up, and it sounds like it is, the easiest thing to do is simply delete the .metadata folder from the workspace (or rename it to something else). Start up Eclipse, it will show an empty workspace, and then use File -> Import to import existing projects back into your workspace. Just point it to the folder of the existing project and it will do the right thing, leaving the project in place.
For the maven stuff, the Import Maven projects mentioned above seems right and probably does some other stuff to have maven work out.
