For unknown reason, files of some types become not open-able in Eclipse IDE, for examples, *.txt, *.am, *.mak. When i right-click on files of those types in Project Explorer view, there is no "Open" or "Open With" menu options shown up like *.cc and *.hh. Those files types were use to be open-able within the same projects.
I confirm that the unopenable file types are associated with respective editors.
What may be wrong with my project or workspace settings?
[2013-09-30-update]
Still find no clue on why all non-c/c++ files cannot be opened by Eclipse IDE running on my Macbook :(
I imported the directories containing the files to create a project on Eclipse. The directories are mounted via Samba.
Any answer will be appreciated!!
Go to windows > preferences > general tab > editors > file associations and check your file type if its not present add them. It will be done.
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 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.
Is there a shortcut to copy the current path/file to the clipboard?
Just select the file tab and hit Ctrl+C to copy file basename into clipboard.
Hit Alt+Enter to bring up the file properties with absolute path and copy it manually.
Additionally you can use an Eclipse macro plugin that can do the steps in one go:
http://sourceforge.net/projects/practicalmacro/files/
There is Copy Qualified Name function in Eclipse, it will copy the full name of the element you select (or element on cursor).
For example :
/MyProject/src/app/Application.java : when you select Application.java in Package Explorer
java.util.HashSet<String> : when you copy while cursor at HashSet<String>
However, it required you to select the element you want.
So, here is what I do.
Make your Package Explorer link with editor, you can active this by click the double-arrow icon at top-right corner.
Set up a hot-key for Show View (Package Explorer) ex : Alt + 1
Set up a hot-key for Copy Qualified Name ex : Alt + Ctrl + Shift + c
Whenever I need these information in current file, I just press the hot-key to call my Package Explorer Since it links with editor and will always select the file in current editor, you can just copy with the hot-key. Then you can use F12 back to your editor, or simply ESC if you use fast view.
Not perfect, but it works :D
There is yet another plugin that supports copying the path along with a number of other related functions:
http://code.google.com/p/pathtools/
Just search Eclipse Marketplace within Eclipse for 'pathtools'.
You can do it with a single keystroke by configuring an Eclipse external tool (a much underused tool in my opinion). Takes about a minute to configure the first time you use it but then it's always available. Here's a YouTube video demonstrating the technique.
An alternative to the answer of Rangi Lin, which provides some additional functionality: The StartExplorer plugin for Eclipse. The solution mentioned by Rangi Lin doesn't work in all cases. It doesn't work in my case e.g. in the Team Synchronizing perspective in the Synchronize view. However, the StartExplorer's context menu command "Copy Resource Path To Clipboard", as well as the default keyboard shortcut for it (Ctrl+Alt+C) works also there.
The advantage of this plugin is that it additionally allows you to open the file manager at the location of the selected file etc.
Another option is EasyShell. It has a single entry in the context menu, under which you'll find copying of the path, opening explorer, a dos box and others (configurable).
Alt+Enter - open properties
Alt+L - go to path location
Shift+End - select path
Ctrl+C - copy
Go to Project Explorer View in Eclipse which is at the left panel.
Click on link with editor.
After linking, your opened file will get selected.
Right-click on the selected file. You will get the option 'Copy Qualified Name' which is just below 'Copy' option.
Open the directory where your project resides. e.g. if your project is 'abc' and it's in the directory 'project', go to the 'project' directory.
In the folders address bar, the address will be like this: D:\project.
Paste in front of this address like: D:\project/abc/source/com/connect.java
Delete the java file name(connect.java) and press enter.
You will be in folder 'com'.
The video demonstrating the technique was prepared for Eclipse in Windows. In Linux you have to change:
External Tools Configurations - Location: /home/username/path/to/script.sh
External Tools Configurations - Arguments: ${selected_resource_loc}
External Tools Configurations - Standard Input and Output - CHECK "Allocate console (necessary for input)"
Create a script /home/username/path/to/script.sh as follows
echo $1
echo $1 > /home/username/clipboard_tmp.txt
xclip -in -selection clipboard /home/username/clipboard_tmp.txt
xclip -selection clipboard -o
I don't know why, but following command echo $1 | xsel --clipboard doesn't work in the script.
It was checked in Ubuntu 12.04 LTS and Eclipse IDE for C/C++ Developers (Version: Kepler Service Release 2, Build id: 20140224-0627)
In Eclipse Version: 2020-03 (4.15.0)
In Project Explorer
Select your file> right Click> Copy Qualified Name
In NetBeans when you go to Navigate -> Go to File you can search for files by filename. Is there a way to instruct NetBeans to ignore some files. It's picking lots of files from a tmp directory in my project which I never intend to open and it's just noise.
You can also add folders to the "Files ignored by the IDE" configuration.
Select Tools|Options and add the folder names to the regex.
NB: I have not yet confirmed that this achieves what is described.
In NetBeans 7 you go to "Project Properties" then to "Ignored Folders" and you just add your folders there.
You can configure include/exclude file patterns on a project by project basis. This feature will allow you to add an exclude pattern for your 'tmp' directory, which will stop 'Go to File' suggesting files contained in this directory.
To configure bring up the project properties (File -> Project Properties), select sources, and click 'includes/excludes' button. I.e.:
In my version of Netbeans (6.9.1 on Win 7), there is no button under Project Properties -> Source in which to enter exclusion patterns.
You have to go to Tools -> Options -> Miscellaneous -> Files and add the necessary file names or extensions under "files ignored by the IDE" in the Ignored Files Pattern field regexp.
For ignoring an entire folder, it is (in my version) on the project properties screen, but not under Sources; instead look at the "Ignored Folders" category.
