I am trying to map my Visual Studio experience onto Eclipse. Right now, I wish to add a file existing somewhere on the file system into a project in Eclipse. I expect it to be copied to the project source folder.
Currently, I see only one way - switch to the windows explorer (total commander, in my case) and copy the file myself, after which to refresh the project.
Can I do the same without leaving the Eclipse IDE?
Thanks.
I had the same problem, but found yet another solution.
Let me state my problem so that we're sure we're talking about the same thing.
I had a file in a directory where a bunch of code files were and some of the files in that directory were shown as "in my project" and some of the files were missing. I wanted the missing files to appear in my project.
I simply selected the folder in my project and pressed 'F5' or right-clicked and selected 'refresh' and the files appeared in my project. It looks like that is the intended way of doing this.
File->Import->General->File System should do it.
There you can select the file(s) from some file system folder to your project (into folder).
Even easier. Just drag and drop the file from explorer into the correct package in Eclipse. It will ask you if you want to copy or link the file(s).
I am a newbie to Eclipse Luna (the 64 bit latest version on Windows 7) but this worked for me:
Copy the preexisting source files you which add to your project.
In Project Explorer, right click your project and select New > File
In the "New File" dialog box, your project's name / folder should be displayed as the parent folder for your new (existing) source file.
Click on the "Advanced" button at the bottom of the "New File" dialog box.
Check the "Link to file in the file system" checkbox.
Click the "Browse" and browse to your preexisting source.
Click the "Finish" button at the bottom of the dialog box.
In my case, I had to:
right-click the project's name
choose "Close Project"
right-click the (now closed) project's name again
choose "Open Project"
Refreshing didn't work for me. :(
Hopefully this helps someone else...
Just found the quickest way to add files:
Copy-paste your file into your project disk directory using your file browser.
In Eclipse project browser select your project.
Click [right mouse button]->Refresh (or press F5 on Windows machine).
Voila
(worked on Neon-4.6.2)
I just got this to work. YMMV
I don't suppose it has to be there, but I put my file, xyz.cpp, into my project's source directory. My project has a source subdir named src, as in ProjName/src.
Right Click on project name (my project was open and the only one open).
NEW->FILE. Put in the filename, xyz.cpp. Click OK or press enter.
The file will open in the editor and complain that it is empty. Close it WITHOUT SAVING.
Reopen the file. It now has its contents.
It turns out that just simply dragging the files into the src folder would work!
Right-click on the file after you have copied it into the project directory. Select Properties... in the left hand pane select C/C++ Build. There will be a checkbox "Exclude resource from build" uncheck that check box.

Current setup:
MainProject which is a Library Project
BranchProject which is a new projects and has MainProject as a Reference
Whenever I debug and a file from MainProject is on focus (actually BranchProject has only graphic and xml layout changes) the Debug window opens a .class file which is read only. I want it to open the .java file so I can edit it directly.
Skyler's answer from this post worked for me:
Opening source code from debug view edits .class after Android R18 update
Here is a summary:
The fix is to right click the Project name in the debug view, and select "Edit Source Lookup..." from the menu. From there, remove the Default lookup path. After that, manually add the associated projects (not jars) that your project references. This is done by clicking Add, selecting Java Project, then checking the appropriate projects.
When you're using a Library project one of the things you're in fact doing is compiling your Library project into a jar and then referencing that jar in your calling Project.
If you right click the Project, and select "Configure Build Path" you'll see a tab called "Libraries", if you look inside "Android Dependencies" you'll notice a list of jar's corresponding to your Library projects.
These jars are expandable, showing you that they have a slot for a source attachment. Usually this would be editable allowing you to directly link the source but in terms of ADT these are already filled and are uneditable.
When debugging these files you're linked to a read-only class file with this attached source. This is because you're not running against source files directly, you're running against a pre-compiled class file. Until the ADT team get this functionality in place, you're pretty much forced to jump to the direct source code and rebuild everything.
EDIT
See #Steven linked answer :)
I faced the same issue while debugging the a .java file using Eclipse IDE. As per my understanding this issue comes when we put the xyz.class file of xyz.java file or JAR at the project build path. Delete the .class or JAR file from the project class path and rerun .java file in the debug mode. This time you see a source not found window. Click on "Source not found" button and check "Find duplicates..." at the bottom of the window. Done your problem is solved :)
The problem is that the class file is preferred over the java (by default), here is how you can change that for Eclipse (tested on NEON 2):
Right-click on the Project in the Project-Explorer, click Properties
On the new window select: Run/Debug Settings
Create a new configuration (or duplicate another one)
Select the new config and click Edit...
Go to the tab Source
Select the Default and Remove
Create a new path with Add..., select Java Library, then JRE System Library
Create a new path with Add..., select the location where the sourcecode is by Workspace folder (if it is a project in the same workspace) or File System directory (it it is not)
I think this depends on, how you set up the dependency in eclipse. You should set up your BranchProject to depend on the source-Files of your MainProject. If you depend on compiles Class-Files is obvious that the debugger opens the class files, because it does not know about the source files.
I found a good solution for me here:
Using Android library in eclipse and jumping to class files instead of source file that is within eclipse workspace
Simply, select each library project your project depends on, and use Top or Up to move it above the projects outputs. Eg. move all library projects to the top.
Open main project properties -> Java Build Path -> Projects tab and add there projects the main project depend on.
Switch to Order and Export tab and uncheck Android Dependencies
Enjoy
If you tried all above hints and it still doesn't work try this solution, it worked form me:
Right-click on the Project in the Package-Explorer, click Build Path -> Configure Build Path...
Select tab Order and Export
select library that you can't reach code and then click on button Bottom
Then click on Apply and Close
hope this can help you
Most of the time it happens when specific source folder are not added in build path Sources tab.
Right-click on the Project in the Package-Explorer, click Build Path -> Configure Build Path -> Source Tab
Add the source folder if your project source folder is not there.
Select Add folder -> select your project source folder specifically. Eg: project_name/src . Then Apply it and restart server.
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 imported an Eclipse project into workspace and after some time I deleted it in Eclipse (from project explorer but not from workspace). Now, I want to reopen it, or import it again, but I cannot import it because such a project already exists in the workspace and when I try to open it, in tab Project -> Open Project, it is disabled. Of course, I can delete the project from workspace and import it again, but this is not what I want. So the question is: how can I open the project, which is in Eclipse's workspace, but has been deleted from the Eclipse's project explorer?
This is exactly what I just ran into. The 'Finish' button is greyed out, as is the check box and project name in the project window. If you try to check that check box the project will not be greyed now, but it won't check. Refresh does nothing.
The trick (or is it a bug) is to uncheck 'copy projects into workspace' hit the refresh button and it will now be checked and you can hit the finish button. Project will now once again be available in the Package Explorer.
(I'm using Eclipse 3.8 and ADT 21.0.1)
These Steps You Have to Follow
Click File menu
In file menu click Import
A window is open Now click General Folder
Now click Existing project into workspace
Then click the select from root directory
Now import project which you want......
You have to choose the project in the workspace, not the zip file with your project. Your project is still in your workspace, and because Eclipse wants to copy the project from the zip file you chose (look at the checked check box "Copy projects into workspace"), you get that warning.
Just select "Select root directory" and choose your workspace as your root directory and choose the project you want to reimport (and make sure, that the checkbox "Copy projects into workspace" is not checked).
Go to “%ECLIPSE_HOME%\configuration.settings” and delete the workspace listed at the key RECENT_WORKSPACES
Restart Eclipse, go to File>Switch Workspace>Other… and select your workspace dir again
Now I could create new projects as always
One simple trick is to delete the project from your work-space directory manually and than try to import project again. That's it...
I've experienced this same problem. It was a deleted workspace which I re-imported. When I tried to work with junit tests in the directory, it said that parts of if were not in the "project" In order to fix this, I had to check the "SEARCH FOR NESTED PROJECTS" and that corrected the issue.
I know that this is a really old question, possibly the solution was not available back then, but on my system (Eclipse Photon 4.8.0) it works like this:
File menu
Open Projects from File System...
Here you can give Eclipse a path to a directory (in this case your own, currently used workspace directory) where it will search for possible projects, list them and let you choose which one to import into the workspace. It will show already imported (aka. existing inside Eclipse) projects grayed out and unselectable, but has an option to hide these as well.
After selecting the project you'd like to import just click the Finish button and voila.
Make sure that your project is included in current workspace, then you have to see the project under "Project Explorer".
Note: you can view this from: Window->Show View->Project Explorer.
If you are facing this:
Some projects cannot be imported because they already exist in the workspace --> "Finish" button is grayed --> hence, no way to open the project(s)
Solution:
Go to File -> Open File...
Choose any one file of your project, and the entire project folder will open in your present workspace.
When we create a (PHP) project in Netbeans 7, it somehow saves the directory in its own format, and later we can open the project in Netbeans. However, I have a project which I created without Netbeans, now I want to open it with Netbeans, but seems that I can not. When I "Open Project" in Netbeans, and browse to the directory, it does not not recognize the directory. So how can I open a Non-Netbeans project in it?
Thanks.
In NetBeans IDE 8.0.1
File->New Project
Select PHP-> PHP Existing Sources, Click Next
Browse Source Folder and Select it
Give project a name
If you want you can keep a backup in a separate directory, Click Next
And select your Server
Click Finish
Select "File" > "New Project"
Under "Categories" select "Java"
Under "Projects" select "Java Project with Existing Sources"
You'll then need to tell it which directory contains your sources and which directory contains your JUnit tests.
Go to the window menu and select favorites. Then a tab include beside projects, files...then drag a folder from file explorer and put it into favorites.
You can either use the "Import Project" from the File menu, which can transform an Eclipse project to a Netbeans one for example (there might be other transformations available as plugins, don't know), or just create a new Netbeans project with your existing code.
Go to File Then New Project
Under "Categories" Select PHP.
Under "Projects" Select PHP Application with Existing Sources, Click Next.
Browse Source Folder and Select it.
Give project a name.
If you want you can choose PHP Version, Click Next
And select your Server
Enter project url or link. (i.e http://localhost/onlinevoting).
Choose index file This file is mostly index.php file or the default file for your website.
Click Finish.

Just copy this template nbproject folder from the archive nbproject.7z to your target folder. After it, you can open folder as NB project. It is just minified NetBeans 8 project definition.
Base64 7z data uri copy
I deployed an application using this method and it worked very good. However, there are 2 missing things that I been trying to find but can't:
1) How do I include resource files in the installation? I have a folder with files that have some user data, and those need to be there after the installation so the application can run, this is an oversimplified example I'm working on (I need to include NecessaryFile1.xml, NecessaryFile2.xml and NecessaryFile3.xml and the folder they're in):
alt text http://img193.imageshack.us/img193/7782/resources.png
2) How can I put the application in the start -> programs menu? It doesn't seem to do that either. It just puts it in the C:\Program Files\My Company Name\ApplicationName\ directory.
Thanks for any suggestion!
Go to your Setup project in Visual Studio. In the "File System" tab, locate "Application Folder". Right-click and then click Add | Folder. Name the new folder "Data". Right-click on the new "Data" folder and click Add File, then add the needed XML files. Repeat for as many different folders and/or files as required by your application.
When you compile and run your setup project, the "Data" folder and its contents will be deployed along with the application.
Click on each XML file in the Solution Explorer and then in the Properties window below (see your screenshot) you click and change "Build Action" to "Copy" and "Copy to Output Directory" to "Copy If Newer". That does the trick for me, at least with ClickOnce...
