I am using eclipse and I moved some projects(Projects with the name Mc Bot) in my workspace to another folder. However, when I open eclipse with my workspace, projects still appear like this in package explorer.
How can I fix that?
You cannot move project folders on your hard drive and expect Eclipse to update automatically. The folders contain metafiles that Eclipse needs to properly load the workspace on startup.
It is better to either rename/move the projects within Eclipse.
Or to remove and then re-add them to Eclipse's project management.
However, make sure to not accidentally delete the files from disk, when removing the old project from Eclipse. There is a checkbox within the confirmation dialog that - in this case - you should not check.
Especially when you are working with a code versioning system (such as Git or SVN), it is important to rename your files and folders within the code editor. Otherwise your repository might get out of sync.
I would just delete it here in eclipse (don't mark the checkbox to delete on disk) and then reimport it. So in this view from the screenshot just open the context-menu, say import and chose your projects again.
I am trying to import a project that me and my co-worker have been working on.. and keep getting this error after I select-- "import" then "import existing project" then click archive file, and then I click next, and this error comes up:
Some projects cannot be imported because they already exist in the
workspace
Uncheck the "copy projects into workspace" checkbox, and then click "refresh" button, you will be able to import the project
go to .project file in your project and change the name of the project in name tag
It has just happened to me too. Finally I realized that the project was already open in my workspace but it was not visible because of the selected working set. You have just to deselect the active working set and all opened projects will become visible.
This usually happens when you change the project directory physically without first delete in Eclipse.
You can view and delete these hidden projects in the following view:
Window -> Show View -> Other -> General -> Navigator
Then simply just continue with the process of import existing project.
In my case, I copied one of the projects (say 'Project1') from the workspace and pasted it to the same workspace. After that I modified the name of the pasted project (say to 'Project2'). I could not see it in the repository.
The main reason was .project file from the new project still had:
<name>Project1</name> instead of <name>Project2</name>.
So, I did following things in order to get the issue fixed:
Cut and paste Project2 outside the workspace
Change .project file to have <name>Project2</name>
Try importing Project2 again.
It worked for me.
You may have a project with same name in your workspace. Try to refresh (file->refresh) your workspace after deleting the another one with same name.
A typical situation occurs when you want to re-import a deleted project.
Projects in the Eclipse workspace must be unique. Note though that the project name need not be the same as the directory/folder name of the project, so you can either delete any existing project with the same name or alternatively rename the existing projects.
You have one occult directory named ".metadata" in workspace directory. Close Eclipse, delete ".metadata" and open Eclipse. When eclipse ask you about workspace make sure that ".metadata" isn't in workspace directory and click "ok" button to select default workspace.
Maybe you get the same project name in your '.project' file,check it,if yes, rename another name.than import again
If you've arrived at this because you have cloned a git project into the existing workspace and now you want to promote that workspace to a full fledged project then you should use the 'Git Repositories' view -> select 'Working Directory' -> Import Projects -> Existing projects.
Check if you have configured Eclipse to show ALL the working set. I once encountered exactly the same problem and it turned out I accidentally imported the project into the Other Projects working set. And my Eclipse configuration didn't show that working set in the package explorer, which lead me to believe that the project was not imported yet.
Updated for #Mawg:
First, click the Select Working Set...:
Then, choose No Working Sets:
This will effectively disable the working set and show all projects.
Try to rename the value of <name> tag which inside ".project" file of your project.
<?xml version="1.0" encoding="UTF-8"?>
<projectDescription>
<name>Rename this value</name>
<comment></comment>
<projects>
This will work for sure. Here you are just renaming your project.
EASIEST WAY: Right click on the project (folder that reads "MainActivity") go to Refactor -> Rename and you will get a text field allowing you to rename your project.
If you get an alert saying your project is out of sync with the filesystem press F5 (refresh) and try again.
Take a look in your workspace folder, you may have an old project there with the same name as the one you are importing (even though it's not being shown on eclipse).
When you delete a project on Eclipse, if you don't check the checkbox on the dialog, it just removes it from the view and doesn't delete the folder on the workspace directory.
In my case i had deleted the resources directory from my .metadata.plugins:
Go to your workspace
Enter .metadata.plugins
Delete : org.eclipse.core.resources directory
Another way I just found!
MOVE the project to some other folder and then import and if required copy to workspace
I had this issue when I deleted a project and tried to import the code again. Eclipse never really deleted the project and still held a reference to the project name/folder in the workspace. I had to created a new project with the same name and my code appeared as it was. I believe this only worked because the project path was never changed.
It was happened to me when
I delete project from eclipse Project Explorer and not checked the
remove content from disk.
Next time when I tried to import same project in workspace then got same problem.
To solve I just did FYI work that every kid can do :)
So How I solved it:
Cut Ctrl + x myProject folder from eclipse workspace to other location ie Desktop
Right Click Navigator (you can get it from Window > Show View > Navigator) and Refresh (it will prompt following dialog)
Just click Yes button and move your project folder back to eclipse workspace directory
Import again!
Now Rock 'n' Role
This warning means you just deleted project from navigator, but the project is present in the working set. Or else your working set has project with same name, so go to work-space directory and delete the project which has the same name and import again.
This worked for me.
File > New > Android Project > Create project from existing source
Location = the location of the project you want to import.
You will get a warning "An Eclipse project already exists in this directory.
Consider using File > Import > Existing Project instead." But you will be able to click "Next" and the project should in effect be imported.
In eclipse click file then select switch workspace then browse and select another folder. Now repeat the same process and this time there will be no error :)
I had a similar problem, I have the same repository I wanted to import twice. I renamed the existing project by right clicking on the project > refactor > rename then imported it again.
My problem was a little bit different.
For example, the project name (what I see) was FooProject and in the imported project, I was looking for the FooProject but I could not. However, Eclipse does not let me import that project because he claims that it is already imported. And then, I have looked at the .project file of the project and I have seen that the actual name of the project was not what I see (FooProject).
The conclusion;
The name of the project (what you see in Eclipse) may be different than the actual name of the project (what maven see). Because of this reason. Please be sure that they are the same name by checking .project file of the project.
Nothing about could not solve my situation. This is how I solved.
Close the IDE
Remove the same name project form workspace
Start the IDE
Clean all project (not sure this helped)
File > Import > Existing Project
click refresh button
import project
Done..
At least on Eclipse Juno, you can toggle on Advanced. Then select [groupid].[artifactid] from the Name Template dropdown. That should make your project uniquely named. (If you keep multiple versions of a given artifact, you can select [groupid].[artifactid].[version] instead). Be sure to click the Refresh button so the changes are visible. Wash, rinse, repeat as needed.
delete it from eclipse......u might have closed the project in eclipse by "(Rightclick)-->close project".....so even if you delete this project from workspace folder....it stays there in eclipse IDE as closed project.....you should delete it from Eclipse IDE...!!!
I have a slightly different situation whereby my eclipse stops responding and I have had to kill the session. After restarting Juno, then the particular project I was working on disappeared although .project file exists. Trying to import back into Eclipse would yield the same "Some projects cannot be imported .." or "A project with this name already exists" if trying to create a new project.
In the end, since I was using Working Sets, I managed to find this file .metadata.plugins\org.eclipse.ui.workbench\workingsets.xml. Manually added the missing entry and restarted eclipse and voila, it came back.
I had the same error because there was one more project under svn in workspace but with another name. So I've removed it.
This is what i have noticed for the above issue :- If the checkout folder (folder where your pom project resides) is same as the eclipse workspace folder then i am getting this issue
SOLUTION
when i used a separate workspace folder for importing the project, eclipse did worked smoothly :)
In case you are using Maven, make sure that your artifactId in pom.xml does not have the same name as any existing project name in your Eclipse project explorer.
I am currently following this tutorial on how to make a Minecraft mod. I have done everything that he has done, but when I open Eclipse and try to open the Minecraft project it give me an error saying:
'Open Project' has encountered a problem.
The project description file(.project) for 'Minecraft' is
missing. This file contains important information about
the project. The project will not function properly until
this file is restored.
How can I fix this error so I can make my mod?
Edit: Here is the errors that I am having...
You need to execute the command:
gradlew setupDecompWorkspace eclipse
from the commandline before you can use eclipse.
go to your start menu
type in cmd
then navigate in the command prompt to your folder where you extracted the mdk
then execute in that folder the abovementioned command.
Then open eclipse and point it to the working directory(eclipse in the mdk folder)
I'm not familiar with modding Minecraft, but from the information you've provided there are a few possible solutions. First you need to check if the .project file actually exists or if it is really missing. Go to the workspace folder as per the video and it should be in the root folder of the project in there.
If it does exist check that you have selected the correct folder for your workspace and the project. If these are wrong Eclipse might not know where to look to find the .project file.
If it does not exist you will need to create one in order to load the project. The easiest way to do this is:
Open Eclipse at the workspace specified in the video. I'm assuming here that you have already downloaded and extracted everything. I think the workspace is a folder named eclipse
Create a new project (File->New->Project). Don't try to open the broken project.
Navigate to the workspace in windows explorer. In here you will see a folder for the broken project and one for the new one you have just created.
Open the folder for the broken project and copy the entire contents.
Go back and open the folder for the new project. Paste everything here. Some things may be overwritten but there shouldn't be anything that causes a problem.
Go back to Eclipse and refresh the new project (Right click on project in left pane->Refresh)
You may want to rename the new project to have the same name as the old project. If you want to do that you'll have to delete the broken project.
Did you move the anything in the Eclipse project folder after creating it?
I used to teach modding to kids and this was the most common error. If you start moving things around without right-click -> Refactor -> Move then Eclipse will become confused and could cause this error.
Another error I'd often run into is if the kid was using a parent's machine and they did not have administrative permissions OR if the internet connection was particularly slow. This caused certain files to be lost when downloaded during those cmd line commands.
Here's how I set my project up assuming you're also on windows:
download forge src (looks like you're using 1.7.2)
extract the contents into an empty folder
point a cmd prompt to this location
run "gradlew setupDecompWorkspace" (will take a while, should exit with "BUILD SUCCESS")
run "gradlew eclipse" (will take a much shorter, should exit with "BUILD SUCCESS")
open eclipse and switch your workspace to the "eclipse/" directory in the same folder you extracted forge into. (e.g. C:\Users\ME\Desktop\FORGE_FOLDER\eclipse)
If follow these slowly and carefully there should not be any issues. If there is then that means you may not have admin privileges or may be on a restrictive internet connection.
Edit: the package declaration issue on line one is because in your project explorer it says src/main/java/com...etc when it should be src/main/java and then that contains the package starting with "com"
To do this, right-click src/main/java/com... -> Build Path -> "Remove from build path".
After this you must drop down src, drop down main, drop down java. right-click java -> Build Path -> "Use as source folder"
Edit: easy way to access cmd in right folder is to open the folder where you extracted Forge and click in the address bar at the top of file explorer and delete what's there, type "cmd" hit enter.
I have an android project running in Eclipse IDE. Lets say it is 'ABC Project'. Some of my collieges have made number of copies of this project, so the project files can be seen in desktop, C://, D:// and even in eclipse work space. Now I don't know project in which location I am running because they have deleted and imported the project folder to eclipse using this copies and they can't remember whether they selected the option 'make a copy to the workspace'.. How can I get this location? I tried to right click on the project and see any option is there but no. Manually finding it using java code (getAbsolutePath()) will return no good, it will return the path in the phone.
Please help.
Did you try right click on project ->Properties->Resources ? You will be able to see the Project path there.
Right Click on project and click on Resources.
In that it shows the location where it is .
Find it out dude :)
Properties -> Resource -> Linked Resources -> PROJECT_LOC
Use Alt+Enter on the project Name in Eclipse to see the complete path of the project directory where it resides.
I have recently returned to a project after not using it for a couple of weeks. The project was not created in Eclipse it was imported, and there is no '.classpath' file in the project workspace.
I am sure that previously I successfully added new .jar files by simply right clicking them and going to 'Add to build path', but thanks to an unrelated error I had to re-add the files to the build path, and now whenever I try to add a new .jar file I get the following error:
Error while adding a library
Reason:
Could not write file C:\Users\Charles\workspace\hive\.classpath
Or, if I try to add a file using Configure build path, I get the following error:
'Setting build path' has encountered a problem.
Could not write file:
C:\Users\Charles\workspace\hive\.classpath
I have earlier versions of this project prior to adding .jar files, and there is no .classpath file for any of them either, so I haven't accidentally deleted it at any point.
If anyone can help me out at all, I'd be ever so grateful (I desperately need to add these .jar files so I can do some actual work).
The thing that annoys me the most is I'm sure it worked before, but I have tried to do the same in earlier versions of the project and I am always getting the same error now.
I had the same problem. I had just setup a new PC, I transferred my projects to the new PC, clicked on the workspace directory, and changed the permission so that I (the 'me' on my new PC) owned all the files in all all sub-directories. However, even after doing this, eclipse couldn't write to the .classpath files. I verified that I could write to them using notepad, and that worked fine. I also verified that the O/S knew I was really the owner, but it didn't help. I also tried running as admin, but that didn't help either.
Then I found this link: http://blog.ryanrampersad.com/2010/03/03/setting-build-path-has-encountered-a-problem-in-eclipse/, which indicates that when you copy files to a windows7 machine, windows may set the 'hidden' attribute on the file, and when this happens, eclipse can't work with it. I did a find files from the workspace directory, looking for '.project' (and subsequently '.classpath'), and selected all the files, right-clicked, and un-checked the 'hidden' attribute. This fixed my problem.
The .classpath file in eclipse is a configuration file (in XML) which stores the project classpath properties. If it can't be written, perhaps it's an access problem. Right-click the file in windows explorer and check under the security tab to see if you have write permissions. You may have to run Eclipse as administrator.
Go to your Project in WorkSpace.
And then change your files' attribute from hidden.
Also, then close-open your project and then clean it.
This should work.
Right click Project >> Source >> Format - worked for me!
Go to the project folder and remove hidden property for the ".classpath" file. Hope this helps. Thanks.
The below solution worked for me.
Go to your project folder --> Right click folder --> Properties --> In general tab, Uncheck the attribute(last field), Read-only (Only applies to this folder) option.
Then try adding jars in eclipse.
Hope this helps
As doc_180 mentioned, the .Classpath would be hidden. Right click > Properties and Unhide the file, you should be ok.
Just had the same issue after trying to create my view on a new PC. The cause of the issue for me was that .classpath file was marked as read-only, for whatever reason. To resolve this I did the following:
Go to workspace directory --> Java Source folder --> Project Directory --> right click on .classpath and select Properties from the list --> uncheck 'Read-only' and/or 'Hidden' attribute checkbox(es) --> Click 'Apply' button.
I had a similar problem after changing my project to Gradle. When I right-clicked on javaw.exe->Properties in the 'debug' view, I saw the classpath was (mostly) missing, for instance the 'bin' directory containing the classes wasn't there.
Solution for me was just to delete the 'run debug configuration' and create a new one. After that the classpath was included and I could run it from Eclipse again.
Hope this helps someone out there.
An intern here just had this problem. He put the project on the user Document folder. I moved his project to the Eclipse workspace folder, removed the project from Eclipse and imported it again. Then the .classpath file was generated.
