I was trying to clone a project in Eclipse and after copying it into the same directory, I got a lot of build path errors, even after deleting the copy of the project. So, I decided to back up the original project, delete it from the directory and try importing it again. However, when I try to import it I get a "Gradle build daemon disappeared unexpectedly" error. I have looked extensively on this and other sites and found no solution, I tried deleting the .gradle folder as well as several others, to no avail. Can someone please help me?
It didn't fix the problem, but I managed to find a workaround by creating a new LibGDX project with the same name and then copying the 'src' folders from each subproject into their respective folders in the new project. Their were still a few problems with the android version, but once I picked an android target and added 'gen' to the source folders in the build path, it worked.

I installed unity 2021.3.6f with android build support (NDK and SKD) using unity hub.
Going into a project and attempting to build it on android platform , I get this error :
FileNotFoundException: Failed to find $C:/ProgramFiles/Unity/Hub/Editor/2021.3.6f1/Editor/Data/PlaybackEngines/AndroidPlayer/Tools\GradleTemplates\mainTemplate.gradle
I looked up in the directory and I don't even have the /Tools folder inside /AndroidPlayer.
Tried to reinstall unity and android module again but even after 2 times of reinstallation I still receive this weird error.
In unity Edit>Preferences>External-Tools>Gradle Installed With Unity is Ticked and marked to the /Tools folder which doesn't even exists
(there is also a warning below that saying I'm missing the recommended Gradle and I should install the recommended version using unity hub. but I already tried reinstalling everything)
I have used the unity android build before and it was always fine, perhaps this happens with the 2021.3.6f version that was released this week.
Can't find any solution to this anywhere, hope you can help.
Found the solution.
looks like the gradle folder has changed from AndroidPlayer\SDK\Tools to AndroidPlayer\SDK\cmdline-tools but the path still the old one inside Unity preferences.
Copy all folders and files inside cmdline-tools, create a new folder called Tools inside AndroidPlayer folder and paste there.
You can consider it as Unity Bug which will be fix in next update.
But for now please do the below workaround to fix this issue.
Go to the below location in the Unity installed folder
/Applications/Unity/Hub/Editor/2021.3.6f1/PlaybackEngines/AndroidPlayer/SDK/cmdline-tools/2.1
Now copy all the files and folders in this folder
Now Go back to the AndroidPlayer folder and create a folder Tools
Now paste copied files/folders in it and click on build and run.
Hope it will fix this issue.
I deleted the release folder which was generated by eclipse (CDT) when I first built my project; but now when I try rebuilding the sources, eclipse does not regenerate the complete release folder along with the make files. Rather, it reports the following error:
Errors occurred during the build.
Errors running builder 'CDT Builder' on project '<project name>'.
Resource '/<project name>/Release/objects.mk' does not exist.
Resource '/<project name>/Release/objects.mk' does not exist.
I'm using eclipse neon2 with cdt. I tried searching for a solution online, but I couldn't find any. How do I solve this problem and regenerate the release file?
I tried refreshing the project, by right clicking the project in the project explorer and then clicking refresh before building the project. The project now builds without any problems and the release folder got regenerated.
It would have been nice if Eclipse did that automatically.
The subfolder myproject/wp-content has dissapeared from the project explorer (of course the files are still there, I can see them on windows explorer).
All the other folders and files are still showing up.
I tried deleting the project files (.settings .buildpath .project) and deleting the project on eclipse and also deleting the index on .metadata/.plugins/org.eclipse.dltk.core.index.sql.h2
What else can I do?

[EDIT] I forgot to mention I've also tried to rebuild the project with the same results, and I've also checked explorer view filters in case something weird had happened but there are no filters set.
[EDIT 2] I deleted the Eclipse project files and the whole .metadata folder on the workspace and recreated the project. I had no problem at first, but it has happened again. I haven't touch any settings, just closed and reopened the project.
[EDIT 3] The less invasive fix by now seems to be a combination of deleting h2 database (.metadata/.plugins/org.eclipse.dltk.core.index.sql.h2 workspace folder) and deleting also the project without deleting its files which doesn't delete .build or .settings or .buildpath either, so it can be recreated without much hussle. I can avoid the problem by not closing the project (I can still close Eclipse without loosing the folder), but I still don't know what's causing it.
[EDIT 4] I updated Eclipse and plugins today to their latest versions (Now runnning Kepler 4.3.2) and the problem persists (even if I delete org.eclipse.dltk.core.index.sql.h2 and .settings, .buildpath, .project before importing the project's folder contents as a new project): I just close the project after eclipse finishes indexing it and when I reopen it wp-content doesn't show up any more (unless I force reindexing by deleting org.eclipse.dltk.core.index.sql.h2 again). I do believe this is WordPress related, since it only happens when indexing this particular WordPress deployment (maybe it's one of the plugins/theme files installed inside wp-content or something related to one of the xml files in the root folder, like sitemap.xml?).
For me this happened multiple times, on different project and different folders. Opening+closing or refreshing the project yield no success.
In my case, I have found out that this is related to the Working sets. It seems by default new subfolders and files of a project are not marked belonging to the set, so the project has a mix of old folders (included) and new folders (excluded).
There are two fixes I am aware of:
disable the working sets
Moreover, on large projects, having this mixed state working set made opening the folder structure (and other operations) very slow (3-5 seconds per level). Turning off the working set filter made it instantaneous.
edit the active working set and check the project's checkbox (which will check all subfolders).
This happens to me all the time. I'm on OSX and my projects are accessed from a mounted samba volume. I've found that if I:
open the project in eclipse
eject the samba volume
refresh the project (it will say it cant find it and ask if you want to delete
it... click no)
remount the samba volume
refresh the eclipse project
And the missing files/folders show up. If your folders are local, maybe just moving the project folder would do the same. Unfortunately, this happens very often, and seemingly more often for wordpress projects for some reason.
I'm working with a UI project (Dynamic Web Project) and my web folder keeps dissapearing too. I didn't knew what causes that.
The only thing I knew was how to reset my projet; deleting it from workpsace and reimporting it.
I know now what causes that but I have no answer on why it actually does it. I keep refreshing my workspace because I have some compressing that is done outside eclipse and for my workspace to update them I need to refresh... somehow, the freaking Close Project option is right under the Refresh option, without prompting... and this is when my folder dissapear; when I reopen it.
Try the Import Existing Project would be my guess!
Maybe that can help you find the how of it !
Hi i solve this problem by unchecking "Group by Namespaces" in the little triangle on the top-right of the php explorer.
Issue:
My app directory in my cake php application became invisible after some time. This is bad since all of my non-cakephp framework files reside therein!
My environment:
Macosx
Eclipse Kepler
WebServer: built in macosx in Library/WebServer/Documents which is symlinked to a dir in my home directory.
PHP plugin
What I tried first:
Deleted old project from UI ( retaining files on the file system )
cd'ed to root project directory and deleted eclipse artifacts like .settings, .project, etc
Recreated php project to find that the app directory is still missing!
What worked for me:
I renamed the directory from app to app_back using the terminal/linux command rn.
Eclipse immediate saw the new dir after a clean rebuild.
I renamed the dir back to app and performed another clean rebuild.
Et Voila
It seems that by upgrading Eclipse to last version (Luna), removing the project files (.settings, .classpath and .project) and creating a new project on a new workspace, I can close and reopen the project without having the folder missing from the project explorer.
It's not the solution I wanted (and don't need any more) but it's also a solution, so I'm posting it :-)
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
delete that, restart the IDE and you're good to go.
I am using Eclipse PDT 3.5 on Vista (32 bit). It works, though eclipse needs admin rights to execute. This annoys me, but I accept it.
But: every now and then (I am not sure, it may even be everytime I want to open a project), I get the error message "The project description file (.project) for my project is missing.".
It is NOT missing, it is in the main folder of the project. It has no special flags set (it is not hidden, nor system file, nor write-protected).
This is for ALL projects I have in my list. The only solution I have found so far is to delete the project from eclipse an re-add it. This is somewhat annoying.
What can I do?
EDIT: The workspaces are on a server volume. Can this be the problem? I used Eclipse 3.3 before, and there it was no problem with the server paths. And the server volume is mapped to a drive letter.
I've found this solution by googling. I have just had this problem and it solved it.
My mistake was to put a project in other location out of the workspace, and share this workspace between several computers, where the paths differ. I learned that, when a project is out of workspace, its location is saved in workspace/.metadata/.plugins/org.eclipse.core.resources/.projects/PROJECTNAME/.location
Deleting .location and reimporting the project into workspace solved the issue.
I had the same problem and in my case .project file was also present in the project directory and had correct permissions.
This problem happened to me after I closed and reopened multiple projects quickly one after another and Eclipse tried to rebuild them at the same time.
In my case Eclipse lost .location file in the workspace directory for 2 out of 5 projects: <workspace>/.metadata/.plugins/org.eclipse.core.resources/.projects/<project name>/.location
I've followed instructions on How to get project list if delete .metadata accidentally and imported the project in the workspace manually via File :: Import :: Other :: General :: Existing Projects. After that .location file was created again and Eclipse stopped complaining.
I had the same problem, and I haven't gotten that error since I close the project before I close myEclipse and don't tidy up the default location.
My project source and compiled files are outside the default workspace but there are stubb folders created by default by myEclipse in the default workspace. When I setup the project, there are two .project files - one in the default workspace that points to the working dir, and one .project in my chosen directory.
If you move the files for whatever reason manually, then Elipse lost the reference and output a missing project file error, but the reason is thaty you move manually the files and Eclipse lost the reference
I am using Eclipse 3.5.1 on Ubuntu. After rebooting my machine my projects in PHP Explorer view were giving the warning that the .project file was missing. The problem was that the external directory where my projects are hosted was not mounted on reboot. So I did a mount -a from the command line and the Eclipse recognized the files.
If you only want to checkout and you delete the folder from the workspace you also need to delete the reference to it in the Java view. Then it should checkout as if it were checking out for the first time.

in the name tag give the name of the project folder
and save this file with .project extension
& paste it in the project folder.
this worked for me.
In my case i have changed the root folder in which the Eclipse project were stored. I have discovered tha when i have runned :
cat .plugins/org.eclip.resources/.projects/<projectname>/.location
Martin Encountered the same issue with a Minecraft Mod project when I changed the Main folder location.
Normally I would open the project like this
This is how my path looked when I started the project
I got the same "The project description file (.project) for my project is missing." Error.
I later found the .project file in the main folder like this.
This is the location where I found the .project file
I found that going eclipse to "File->Open Project from File System or Archive" and navigate to your main project folder with the .project file solved the problem.
My project is already included
This is my first post in here hoping it can help you out, Martin.
I created a new workspace and imported old projects. I just didn’t open this workspace for a long time, I don’t know why this problem happened
In my case it happened cause I accidentally removed eclipse metadata files.
So I fixed it by removing the project from eclipse, but without deleting files from disck.
And then reimport.
If you keep a backup of your worskpace folder, then all you need to do is restore the following folder from the backup:
workspace/.metadata/.plugins/org.eclipse.core.resources
It worked for me after I created and switched to a new workspace and copied my codebase there.
