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 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 am just trying to compile and run a simple java program. When I go to run my tester class it says select what to run and it gives me Ant Build which when highlighted says "Launches an Ant build with default settings" or Ant Build... that says "Launches an Ant build and allows it to be configured". When I try to select either of these it prompts Build failed. Reason: Unable to find ant file to run. I honestly don't know what these ant builds and files are. This is definitely a dumb question but have no idea what to do.
Make a project to put the files in.
File -> New -> Java Project
Make note of where that project was created (where your "workspace" is)
Move your java files into the src folder which is immediately inside the project's folder.
Find the project INSIDE Eclipse's Package Explorer (Window -> Show View -> Package Explorer)
Double-click on the project, then double-click on the 'src' folder, and finally double-click on one of the java files inside the 'src' folder (they should look familiar!)
Now you can run the files as expected.
Note the hollow 'J' in the image. That indicates that the file is not part of a project.
I was also in the same problem, check your build path in eclipse by Right Click on Project > build path > configure build path
Now check for Excluded Files, it should not have your file specified there by any means or by regex.
Cheers!
right click somewhere on the file or in project explorer and choose 'run as'->'java application'
This worked for me:
Create a new project
Create a class in it
Add erroneous code, let error come
Now go to your project
Go to Problems window
Double click on a error
It starts showing compilation errors in the code.
Your project has to have a builder set for it. If there is not one Eclipse will default to Ant. Which you can use you have to create an Ant build file, which you can Google how to do. It is rather involved though. This is not required to run locally in Eclipse though. If your class is run-able. It looks like yours is, but we can not see all of it.
If you look at your project build path do you have an output folder selected? If you check that folder have the compiled class files been put there? If not the something is not set in Eclpise for it to know to compile. You might check to see if auto build is set for your project.
What I did was I created a new project and opened the file location from my old project and new one. Then I copied everything from the old project besides the run file, and ran it on the new project and now it works fine.
the file is probably located in your project package but is not yet compiled so you are able to open it as a java file in your eclipse java project, here is what I did in my case: in eclipse, goto terminal window, cd to your project directory, then cd to your project package, then run javac yourFileName.java, finally right click your java project or project package in the project explorer and... you should see the file there, and it should now run for you as a java file... hope this helps!!!
My directory structure in the Project seems to have disappeared. The first picture is the "bad". I recently upgraded to 12.1 and the vim emulator at about the same time. I don't know if I missed a dialog that reset something? I can't figure out how to get it back like the second picture.
I've tried to re-import the project but it has not helped. I keep the project on Dropbox and have another PC where I have not reloaded project. Is there a way to get my view from that machine?
The picture is the "good" and how I want it to look.
I've come across this problem a few times myself. What happened is that intellij lost the module in my project settings. Here's my steps to fix it:
File -> Project Structure -> Click on modules (notice empty list) ->
Click on '+' -> Click on import module -> Find existing myProj.iml
I also have quite a few IntelliJ projects and also git folders of text files. I found IntelliJ does not always reconstruct the .idea files correctly. However the following methods work for me.
Open IntelliJ in the top folder where there is no .idea folder. Often IntelliJ will just construct a new .idea folder and works.
Copy an .idea folder from a similar project and modify to fit. The xml files in the .idea are reasonable to modify.
Open IntelliJ in the root project level works for me.
I have a mixed project folder tree like the following:
git_root
- proj_android
- proj_ios
- proj_react
- lib
- src
My problem is that when I open IntelliJ on my proj_react folder, I could not see my src folder or lib folder. (My proj_react is one level down from my git_root.)
Then I open IntelliJ on git_root, I could see everything. The problem is solved.
If you are working on a software development project where you are using Maven, Gradle, Flash Builder etc., the below mentioned steps should restore the project structure:
Ctrl+Alt+Shift+S (or) File>>Project Structure
Select 'Modules' in 'Project Settings'
Alt+Insert (or) Select '+' to add a new module
Select 'Import Module'
Select the folder you want to import the module from(Generally the parent folder)
Select 'Import module from external model' and the corresponding external model
This resets your project structure.
You can sometimes rescue projects like these by going and resetting their content root in the module settings. Or even recreate the module as another answer suggests.
This is something that would happen to me if I opened an IntelliJ project in PhPStorm, then tried to open it in IntelliJ again.
However as was mentioned the project format changed recently, so you should use the same version of intelliJ to work on your project.
If you have a content root for a project module that intersects with another content root, then this problem will occur. For example:
Project A (content root)
- source for A
- module B (content root)
- source for B
If you have a project that has a source root for "Project A" and you add a source root for "module B" you will end up with missing structure, such as your first picture. This happens because the content root for module B is within project A structure.
This worked at one time, as I have the setup above with multiple modules. When I upgraded to 12.1.6 this stopped working. If you have overlapping source roots you will see this problem.
I'm using 12.1.6 on windows 7.
On Mac:
Preferences
search for Project Structure or go directly to:
Project: Your_Project_Name / Project Structure
Mark all as Sources (mine was marked as "Excluded")
What did you update from? If you did a few major versions update, intellij really changed how their projects are laid out. You probably need to edit the projuct structure and add a new java module.
This issue is 8 years old and the problem still exists in IntelliJ. For projects with many modules, it can be a real pain reconstructing them after each time this occurs. I suggest that once you reconstruct the modules, back up the .idea folder so you can easily restore it next time
In the bottom left corner of IntellIJ you'll find an icon, using which you can fetch project structure, etc..,
This is the quick fix that i have done:
Close the IDE and open the project folder in file manager
Delete the .idea folder and reopen the project in IDE.
To view the hidden folder and files:
Open the folder and press cntrl+H (in linux), And in windows Go to folder options and check view hidden files option.
I have just started playing with Java, and I really like the language. I am using the NetBeans IDE, and I find one odd oversight. I can create a new class in a project, but NetBeans doesn't appear to support any way to import an existing class into a project.
I manage to get it done by going to some other project where the desired class already occurs, and then I copy/paste it into the source code folder of the new project, then change the package name at the top of the pasted file to match the package name of the new project.
Is there a nice direct way to do this from the NetBeans interface?
Thanks for any help on this.
In the Projects window you can expand the project that you are working on. Right Click on Libraries and select Add Project.... You will get a dialog allowing you to select another Netbeans Project with the Java classes that you wish to use.
You have to just make the .jar file of that/those java files which you want to use in another project.
right click on file->export->java->.jar then finish.
Now you can use these jar into your another project.
When you build the java project in netbeans it creates a jar file on the dist folder in the current project directory.
You can use this jar file for the other project as a package by adding this as ADD jar in the next project.I have tried this ,i am using my old project jar file for new project development.
Use the 'Clean and build' your project option from the netbeans application, that creates the 'dist' folder which you are looking for (and obviously can't find because you havn't cleaned&buld)
The netbeans itself creates .jar files and you can add the jar file to the current project you are working on.
