Edit existing directory in eclipse - eclipse

This might be a dumb question, but I have a project I am trying to edit a few files for and using eclipse 4.20.0 as an IDE.
When I try to import the directory in eclipse, it creates a completely separate eclipse workspace directory and stores the files in there for my editing. (When I make changes, files in the eclipse workspace directory are changed, but not the original directory)
Is there a way to open the original directory in Eclipse and edit files directly in there? Or am I going to have to work inside the directory eclipse created and then manually move the files over every time to test them again?
I swear I've done this before, but it's been a few years so I might just be importing the directory wrong.

If you are only making a couple changes, just clicking on the .java class you need in your explorer and "Open With... -> Eclipse IDE" will allow you to edit the specific file without opening up a new project. If you are trying to open the project and work on all the files at once, File > Open Projects from File System usually works pretty well on eclipse. If you are opening another eclipse project, just click on the folder where the .project is stored when opening, not necessarily clicking into the folder itself.

Eclipse workspace corrupted after saving as zip

I have a need to share an eclipse workspace as a zip file. However, when I zip the workspace and then unzip it all of the user configuration is lost including the project that was opened in the workspace, what views are showing, and even a JBoss server that was created.
If I copy and paste the workspace everything works fine.
If I zip and unzip all of the configuration is lost (i.e. when I launch Eclipse and use the unzipped workspace Eclipse opens with all of the default settings including the welcome page).
What could be causing this and how do I get the zip to work?
I know there are other ways to export Eclipse configurations but I do have a specific requirement that this be provided as a zip file.
It looks like the problem was with the file names that started with ".". I re-zipped with WinZip instead of the built-in windows tool and everything is working now. See: blog.robertelder.org/zipping-corrupts-eclipse-workspace

Eclipse won't show files in package explorer

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)

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.

"Sources directory is already netbeans project" error when opening a project from existing sources

I've installed NetBeans 6.9.1 and installed few updates for it.
Then I've created a new project from existing sources. After a few changes I've closed it. And now I am having an error, when trying to open a new project from existing sources (the same files):
Sources directory is already netbeans project (maybe only in memory).
After Googling it, I noticed it happened not only with me. But I didn't find the correct solution. I've tried to restart the IDE, I've tried to restart the PC, I've tried to reinstall NetBeans. Nothing helped.
Thank you!
I was having the same problem:
Sources directory is already NetBeans project (maybe only in memory).
Netbeans creates a folder in your project named "nbproject". Once you delete that, restart the IDE and you're good to go.
When you create a NetBeans project from existing sources, NetBeans uses the same directory to add its own files: a netbeans folder with .proj files.
Solution: delete the netbeans folder and restart the IDE. Opening a new project should now work.
Go to the folder containing your project
Delete the folder named nbproject
Restart Netbeans
Try creating your project again from the original folder
This means the project folder is already a netbeans project. So instead of adding it as a new project open it as
This happens(i believe) because netbeans tries to version control the files created or edited.
Under the project folder netbeans create a netbeans directory just delete it . This has been tested in Ubuntu. Then you can import your project if php then php using existing sources.
Click File >> Recent Projects > and you should be able to use edit it again. Hope it helps :)
On Windows at least none of these answers work (for me anyway!). I have found the only way is to copy an existing netbeans project folder in to your new project and manually edit the xml project name.
I also opened the private/private.xml and removed the open files xml just incase these caused problems.
Once I'd done this the project works as normal.
I checked the "Put NetBeans metadata in separate directory" tick and it works fine.
This is in 2. Name and Location after you choose PHP from existing source
In my case my project root directory consists ".project". This contain the XML reference of the project name.
By removing this, i am able to create a project.
Usually this happened when we copy source code of a already created project and copied in different folder and try to create a project from it. as netBeans create its folder nbproject in our project folder this folder also get copied with our source code and it give error "Sources directory is already NetBeans project (maybe only in memory)" remove this folder from you newly copied folder and voila you can create a new project.
If this is your own source code and you already have a Netbeans project folder with your source files you should just start with:
File | Open Project...
not
File | New Project ...
because the project is not new.
If it helps anyone else, I had the same problem and the solution was to reinstall NetBeans.
I had tried all sorts of fixes: Deleting the NetBeansProjects folders, checking/unchecking "Put Netbeans metadata in a separate directory", killing/restarting NetBeans, restarting the system, etc. Nothing cleared the message...except the reinstall.
The advice here about removing the nbproject directory is not quite the whole story.
What Netbeans seems to do (and we are guessing at reverse engineering here) is to look for an xml file which has opening and closing project tags in it. This it concludes is evidence of an already existing project. Now if your files have an nbproject directory there, that will contain a project.xml file which contains the said tags. So removing that will do what you want.
But, my files don't have a nbproject directory but still NetBeans tells me there is an existing project maybe in memory. The reason is: my files include a file called pom.xml and that contains the said project tags in the xml (it was created by an entirely different system). Once that xml file is removed, then NetBeans will create an html project for me importing my code.
In sum: look through any xml files in you existing code, and be wary of project tags.
This happened to me when I tried to import an Eclipse project in a brand new NetBeans 7.2.1 install on Ubuntu 12.04LTS.
I mistakenly selected the import projects from workspace (the first option in the import wizard's opening pane) on the first attempt, and it opened the project in the original Eclipse workspace path (which was on a usb stick).
From this, I then realized that I actually need the second option - import project ignoring project dependencies, which lets you specifically choose source and destination folders. After closing the project, I tried to import again with the proper option, but it didn't work.
From then on nothing I did helped - restart the IDE, move the source folder, nothing. There was no nbproject folder in the project or /var/cache in the user folder to delete (in-fact there was no nbproject folder in the whole file-system).
Since restart didn't work, I'm guessing that there is a garbage project entry somewhere which Nb reads (See Martin Frické answer above).
After googling along the lines of 'netbeans clear memory project cache' with no success, I opted to reinstall NetBeans -
sudo /usr/local/netbeans-7.2.1/uninstall
sudo ./netbeans-7.2.1-ml-javase-linux.sh
which solved it.
If you are on a Mac, press command shift G and in the box type /users and then go, next click on your user name and navigate to netbeansprojects and open it. Then delete the ones in there that are causing problems. You can then create your project.
Note: I had moved my wordpress folder to my desktop trying to figure this out, so I dropped it back into the origional location and it works fine. So if you did this, just replace the wordpress folder after deleting the problem projects from the netbeansprojects folder and its contents back to the original installation folder.
Hope this helps...:)
This is what I did to solve this error:
1) I copied a folder named "folder1" (and I called the new folder "folder2"). "folder1" was a Netbeans project so it had a folder called "nbproject" inside it.
2) When I tried to create a project out of the "folder2", Netbeans threw an error "Sources directory is already netbeans project (maybe only in memory)."
3) Inside Netbeans delete the project of "folder1". Then, delete the two folders named "nbproject" (one is inside "folder1" and the other is inside "folder2").
4) Inside Netbeans, create two new projects: one for "folder1" and another for "folder2". The error should not appear anymore.
copy an existing netbeans project folder in to your new project and manually edit the xml project name.
reinstall netbeans
copy/move all files/folders (except nbproject/ folder) to a new folder for your project, with a new name.
Try to create a new empty project; then you can copy the public_html to the new project folder and it will appear .
I faced the same issue:
Sources directory is already NetBeans project (maybe only in memory).
The solution is:
Netbeans creates a folder in your project named "nbproject". Once you

In Eclipse, how can I move all my source files to a different folder without screwing up the project?

I have created my ActionScript source files in a folder on a Mac (I normally use Windows), and somehow managed to make an Eclipse/FDT project that can see them.
I now need to move them into a svn checkout of an existing project to get them under source control.
I just can't work out how you do this without losing all references in the project.
I'm new to Eclipse and don't really understand any of the terminology (e.g. workspace). Does Eclipse have project files or are they all hidden? Can the project file be moved?
Help me stackoverflow, you're my only hope.
Update:
From the FDT Flash Explorer window I can only seem to be able to move files/folders within projects that exist. Should I create a new project in the place I want first?
Should I move them from within Eclipse or from the file system? Do I need to setup a new workspace afterwards?
The project folder has 2 hidden files: .project and .classpath that have all the info of the project. You just need to copy those files along with your project files.
For instance, you have a project folder in workspace/myproject/, and you want to add it to a checkout svn folder, you just need to copy the complete folder content to the checkout and then add all the files to the svn (including the project hidden ones) and finally commit.
From now on, when you checkout from that svn, you will have the eclipse project files, so all you need to do is create new project, and select the option that says that you already have a project folder with the source files (I'm not near an eclipse IDE to tell exactly the steps, but it's something like this). Eclipse will then import the project with all the settings you had previously defined.
I hope that this answers your question.
Try refactoring your project. Rightclick on the folder to move and then choose Refactor->Move. Don't know if this will solve your problem but it will try to change the references in all projects according to the move.
