I have a project called card server2. It disappeared from my package Explore and I can no longer work on it. The files are still there. I try to use import to get it back. But there was a message saying project already existed in workspace.
his happen after I imported a project called chat server, which is working fine.
I was thinking about creating a new workspace and importing the project into this, but then I would have one work space with all my projects and one for just that project.
any ideas would be great!
You can reimport your project after moving it to another location ;)
Cut and paste the project from your workspace to another location and import it back. It should work fine.
navigate to window-show view-others-java-project explorer. if it already open close it and re-open it and you will find it .Hope that help.

My Eclipse installation suddenly stopped showing import suggestions. If I type a class name that isn't in the current package, autocomplete works fine and shows the class, but after picking from the drop-down, the class name is highlighted as an error with the message "MyClass cannot be resolved to a variable". This error shows no Quick Fix suggestions. However, if I manually add the relevant import statement at the top of the file, the code compiles and runs fine.
I've checked my build path and everything appears to be in order -- and like I said, the code runs when I hand-jam the import statement -- but losing automatic importing is really slowing me down. Any idea what could have gone wrong? It worked fine last week!
ETA: Another note, if it helps: F3 still opens the class declaration, so Eclipse clearly knows what I "mean", even without the import statement.
Also also: Things that have not helped:
Clean all projects
Restarting Eclipse
Restart computer
Delete .metadata from workspace, re-import project
Start new Java project, re-link source folder, re-add dependencies (not using Maven, but that's not my choice)
Thanks for all the help, everybody, but this turns out to have been a case of a broken Eclipse install.
I still haven't figured out exactly how or what was broken, but I tried to make a new project with a single "Hello World" class. The New Class wizard errored out with "Creation of element failed" in the class org.eclipse.wst.jsdt.internal.core.dom.rewrite.ImportRewriteAnalyzer. Once I hit "internal errors" in Eclipse, I gave up and installed a fresh Eclipse from a new download.
With a new Eclipse, I got my Quick Fix suggestions back, as well as automatic imports. I guess in future I'll try reinstalling Eclipse before I go looking for solutions to obscure errors like this :-/
These kind of situations can occur if your workspace went into a bad state or eclipse was unable to properly save state during last exit of workspace.
Try Project > Clean and clean all projects and rebuild all. See if this helps.
Clean all your projects. Then update Eclipse. Then restart of Eclipse. Then restart your development PC.
This happens to me sometimes too, I follow these steps and the problem always goes away.
If none of the other answers works, one brute force suggestion which sometimes resolves weird issues like this would be:
Close your Eclipse
Delete the .metadata folder inside your Workspace folder
Restart Eclipse
Note: This way you're going to lose all your workspace configuration. I advise you to backup it first in case it doesn't works.
I'm creating a clean project on ADT and I noticed that the gen folder is empty (with no R.java in it), not letting me run the project. I'm running ADT with all stuff up-to-date (as you can see here)
I already cleaned and built it in every possible way. I also tried to reimport the project, and nothing. There are no errors in the XML files.
I searched for a solution and I found a lot of people with the same problem, and in most cases the solution was to update the SDK tools, but it didn't work for me.
Is there a reason for this?
at the top of screen, click build -> rebuild project
Give it a few seconds. it worked for me, i hope it save you aswell
im using Android Studio(beta) 0.8.9
My R disappeared after i fiddled with sound files in my res/raw directory(converted them to different formats, figuring out how SoundPool class works...and suddenly there is red "R"'s everywhere!
Try right clicking on the project, then going to Android Tools > Fix Project Properties.
If that doesn't work, then try cleaning it before and possibly after that.
If R.java disappears, you usually have to recreate the project from scratch again.
There are many reasons for R.java missing issue, i use to face this issue frequently, some of my thoughts to debug this issue.
Try creating another test project using File->New->Project->Android->Android Application Project. After creating the project run the project in emulator. If every thing works then your setup is perfect.
Check your imports section of your java files, some times default R.java gets included which is from android package. In this case Remove that import and add correct import statement.
Check your "res" folder all the xml's should be well formed and valid.
Hope these debugging steps may help to find the root cause.
try deleting the r.java file in gen folder. when you run again after cleaning and building the project. It should recreate those files and it should work after that. Try that.
Other wise you might have to reinstall Eclipse as you have tried in so many different projects
Something I just noticed was that after I removed the auto-generated code for the menus (which I wasn't using) it started causing errors. Eventually when I cleaned with the menu xml's still in the file structure, my R file disappeared. I removed all entries in the menu folder and then cleaned again. This worked for my specific instance. Hope this helps others as well.
I am using Intellij IDEA as an IDE for running Java programs. Dues to power fluctuation computer got restarted. Now when I launch the IDE after reboot i am getting the error Cannot convert project: /home/aniket/IdeaProjects/JavaDemoCodes/.idea/workspace.xml: Error on line -1: Premature end of file.
Has anyone encountered this situation before? What can I do to view my project back again?
I also had this after a power failure, I simply deleted the workspace.xml file from the projects .idea folder, restarted IntelliJ and it seemed to be OK apart from loosing which files were open.
Cheers,
Nick
I had this exact error when my laptop bluescreened. I solved it by:
Exit IntelliJ IDEA
Rename .idea folder
Start IntelliJ IDEA
Create new project from existing sources
Exit IntelliJ IDEA
Copy all files from old .idea folder to newly created one.
Restart IntelliJ IDEA
Finally solved the problem. Hers is the solution. First of all I had two Intellij IDEA projects open in two separate windows.
One was the project which had corresponding subversion repository. This was a file-based format project. Files that define a project are .iws, .ipr and .iml. .iws is the one corresponding to the workspace configuration. I just reverted back this file with svn revert project.iws and I could launch my project again.
But the problem in second project JavaDemoCodes still persisted as it was custom project I created and it looks by default we get a directory-based format project instead of file-based format project. This has all its configurations in /home/aniket/.IdeaIC12 directory. As many of you suggested i searched for workspace.xml here but could not find it. I tried find . -name *.xml but i still could not find it(Also as the error suggests there is no file /home/aniket/IdeaProjects/JavaDemoCodes/.idea/workspace.xml ).Finally I did import project from my first project(the one with svn repo) it detected my JavaDemoCodes project as Intellij IDEA project and let me open it in new window.
Not sure if this is the perfect answer but it solved my problem and yes as someone suggested I deleted .iws file from my 1st svn repo based project and tried to restart but was of no help. New .iws file was created but it still gave me the same error.
I have experienced this same problem. It happens to me when I have IntelliJ open and for whatever reason (usually problems with having multiple VPN connections open), my computer freezes and I have to do a forced re-boot.
My solution is to use Windows 7 restore. I'll go to the folder it is complaining about, right click on it, and do a restore. If I'm lucky, I have a restore point only a few days old.
For me, rebuilding my configuration on several projects from scratch is too time consuming. Using a restore point from a few days or even a week makes more sense.
Good luck.
I solved it just by creating a new project, then starting it and then reopening the old project..
So I'm having some problems with importing an existing project, everytime I import it and try to run it, the app crashes. I already did my research and people say that it usually helps to create a new project and then paste the existing one over the new one. I tried doing that, I simply created a new android project, and then pasted and overwritten it with my existing project. But that gave me a whole lot of errors so I probably did something wrong.
Could someone tell me what people usually mean by saying to create a new project and then paste the existing one over? My existing project that I'm having trouble importing us using 3 library projects and a few external jars. Thank you for any kind of help!
1st Alternative:
Create a new Project, but when you chose to create a new project, Choose --> Create Project from existing Code, and move on with the settings. You should be good.
2nd Alternative:
Put all source files into one directory named after your project. i.e. "ProjectName" You can keep this directory in your workspace or it can be somewhere else.
Start a new project in eclipse and name it using that same project name.
Uncheck the "use default location" box and find the directory where your project is unless your project is already in the workspace - then you must not uncheck the "use default location" box
Click 'next'.
Let me know, if it helped.
Import for Existing Project into Workspace ?
I got a new laptop and copied all my eclipse stuff from my old laptop to new one.
It was actually the same laptop model just upgraded a few things (mem, drive size, etc)
So the drive letters are the same as the old laptop.
When i originally opened eclipse i got an error message and read on this site to delete the "org.eclipse.core.resources" folder in .metedata/.plugins folder.
So that go eclipse to open.
After opening i dont see any of my projects even though the workspace is already set correctly.
So i tried importing android project and eclipse project but i get errors saying the packages are already there. even though i dont see them in the project explorer.
Whats the easiest way to get my projects back?
If you want your projects on your workspace again, you can go on File -> Import. It will open a modal, then you select General -> Existing Projects In Workspace. Now just select your root directory and it will list all of your projects to be imported.
One important thing is that this method does not import things like Working Sets. If you had your workspace customized, it won't bring any of these customizations back. Still, it is better have your projects back than nothing.
EDIT:
As it didn't work, you also can delete the .metadata folder and it will be like you never had this workspace. After that, you can try to import the projects again.
