[eclipse] 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...

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).

1. I put all of files in src folder into zipp file, and moved this file to some arbitrary folder (Home folder in my case).

2. Go back to src folder and delete all of .java files (you won't be needing them anymore).

3. 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.

4. 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?

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.

Here's a specific problem I ran into when downloading a project from the internet.

1. Make sure you unzip correctly if it's zipped, you can sometimes get an extra level.
2. Make sure you place the project in the project file, not directly in workspace.
3. 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.
4. Import the project from the file workspace. It will look for a folder called projects, your's should be inside it.
   
   Hope this helps :)

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.

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.

For Juno: (With Source in E:\workspace and destination in C:\workspace)

1. Copy project directory in its entirety to the workspace directory. (e.g. Copy E:\workspace\HelloWorld C:\workspace\helloWorld)

2. Start Eclipse.

3. Perform: File --> Import

4. Select: General -- > "Existing Project into Workspace"

5. "Next >"

6. Check "Select root Directory"

7. Select with "Browse Button"

8. Select "C:\workspace"

9. 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.

I had the same problem over and over again the solution that a have found works for now

1. Close Eclipse.
2. go to workspace.metadata.plugins
3. remove org.eclipse.core.resources
4. Start Eclipse
5. Do File->Import
6. General->Existing Projects into Workspace and import all the project from the workspace

As I had imported my project from a "git clone", I had to select File->Import-> Git->Project from git -> Existing local repository

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.

1. Netbeans allows you to do a simple filecopy. As you know, Eclipse doesn't work like that. You must explicitly "import" files and projects.

2. If you do import, and if there are no problems, then they should show up.

3. I'd consider:

   a) making a backup of your existing workspace

   b) deleting and reinstalling Eclipse

   c) Trying another "test import"

Or you could try:

1. Go to File -> Switch Workspace
2. Select your workspace (if shown)

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

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!

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.
