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'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.
I do not see some of my files in the Eclipse Navigator view (or Projet Explorer or PyDev Package Explorer).
I tried to go to "Customize View..." and remove all filters. It didn't show *.pickle files, but it did unhide some other file types (.* resources).
Remember to refresh the view: Right-click the background of the Explorer/Navigator view to open a context menu, then choose "Refresh" (F5).
Restarting Eclipse doesn't help.
If you are using a Working Set, you can try the similar procedure that helped me with PHP Explorer and Navigator.
Look for the answer with pictures here:
Folders and files don't appear in PHP Explorer in Eclipse IDE
I generally have my working projects sitting on folders on my Desktop. When they are completed I just move them to a c:\dev\. The thing is I'm doing it in a rather archaic way.
1. move project files
2. delete project on Eclipse
3. create new project on Eclipse on the new location
How to you guys move projects around?
If I could alter the: File -> Properties -> Resource -> Location path it would be dead simple!
Example move:
c:\user\desktop\project_123
c:\dev\project_123
Right click on the Eclipse project in the Package Explorer, select Refactor, then select Move... In the dialog that comes up, enter or navigate to the new location and click OK. This will also preserve your CVS or other SCM metadata, but will also bring all your modifications as well, and you won't lose any memberships in Working Sets, launch configurations, or other things that Eclipse associates with your project.
Use Eclipse's Move menu item
Open Navigator view, right click on your project and click Move. Then select the destination directory.
Navigator View > Right Click > Move
Note it doesn't seem to work in Package Explorer (at least not in Neon). The move dialog from Package Explorer is different, so use the Navigator window.
I don't know whether eclipse has made modifs since the date of this post...
In my case I had moved a project folder manually and I wanted Eclipse to open the project on this new location. This is what I did (and it seems to work).
(I'm using eclipse "helios" v 3.6.2)
File menu | Import ...
General | Existing projects into Workspace
Select root directory = top directory of your project on the new location
Finish
I rarely have any projects in Eclipse that aren't under source control, so all I would need to do is check the project out in the new location.
If you don't have source control, Eclipse works with CVS rather well out of the box, and it's pretty simple to setup CVS to run locally without a server: http://www.tortoisecvs.org/faq.html#cvsinit
WHEN EVERYTHING ELSE FAILS:
Copying an Eclipse project from one directory (let's call it old_dir) to another directory (let's call it new_dir):
Open Eclipse and specify the copied working directory in your new_dir.
Once it opens the project in the this new_dir, the projects listed under Project Explorer Tab might still be the ones contained in the old_dir (you can check it by right clicking each and following through: "Resource -> Linked Resource" to see the Path Variables values). Thus, they have to be removed from this work space. Delete the Nios 2 Application Project and the BSP Project from the Project Explorer Tab by right clicking on it and selecting Delete option which will pop a new window. In the pop-up window, make sure that the Delete project contents on disk check box is UNCHECKED before clicking OK to delete the Projects. Otherwise, it will delete it from the old_dir where you copied the project from.
Right click in the Project Explorer Tab Area → Import → General → Existing Projects into Workspace and add the copied Nios2 Application Project and the BSP Project from the new_dir.
Right click in the Project Explorer Tab Area → Index → Rebuild, otherwise the Nios2 Application Project will not be able to use the includes provided by the BSP Project.
Click on Project → Clean → OK to clean and rebuild the whole project.
When using console to talk to the NIOS, make sure elf's path is updated to the new project directory as well!
Right click on your project->copy.
right click in project explorer free space and right click->pase.
chose new folder and project name.
I copied the whole project to a new directory. After setting Eclipse to the new workspace it recognises the project instantly. Thus it was nothing further to do. I use Eclipse IDE for C/C++ Developers, Version Luna Service Release 2 (4.4.2).
For Eclipse Oxygen, to move a Java project, djb's accepted answer works well (in my experience just now), except having read comment by Basic May 14 '12 at 9:27, I tried to add my project XMLDiff to C:...\SVN\trunk\Internal Projects, and I got a failure with the rather cryptic message:
Problems encountered while moving resources.
Resource already exists on disk.
I had to move the project to C:...\SVN\trunk\Internal Projects\XMLDiff by creating a new folder, XMLDiff, in the browse dialog, and the result was C:...\SVN\trunk\Internal Projects\XMLDiff, not C:...\SVN\trunk\Internal Projects\XMLDiff\XMLDiff.
So this must have changed between Basic's experience in 2012 and Eclipse.3.
For Eclipse Oxygen
Project Properties -> Resource -> Linked Resources -> Linked Resources (Tab)
In Java projects in Eclipse version 3.4.1 sometimes the folder "Referenced Libraries" disappears from the "Project Explorer" view. All third party jars are shown directly in the root of the project folder. The project compiles and runs fine. It seems to be a GUI problem.
How can I get this folder back?
First, bring up the "Package Explorer" view (instead of the "Project Explorer" view).
Then, if the referenced .jar files still are visible in the root of the project, click on the little "down arrow" icon in the top-right corner of the Package Explorer view. In the context menu that appears, one of the items on the menu is "Show 'Referenced Libraries' Node." Click on that menu item.
I've been struggling with this thing for a while in Eclipse Juno because it's a little bit different.
click the little down arrow as before
click Customize view
check Libraries from external
For those hitting the issue today (Kepler): it is possible that you are in the "Java EE" perspective, which by default has the Project Explorer. Simply switch to the "Java" perspective and it will replace Project Explorer with Package Explorer, which will have the missing Referenced Libraries folder.
Make sure you're actually in Project Explorer and not in some other view like Navigator, like my friend was...
Use the Package Explorer view instead of the Project Explorer view.
