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 checked the src folder (inside the same folder that I have my eclipse folder in) to make sure all the class files were there. There were none, in fact it looked completely different and out of sync from my project.
Is there some other folder or place where eclipse keeps my code ?
By the way, I use Mac. Also, don't think it should be a problem but I keep my eclipse application on a flash drive (the actual install location for eclipse is on my computer, though).
Right click on your code base in eclipse & select properties. In the properties tab you will find the disc location of your project.
When you first setup eclipse you are asked to choose a workspace. The workspace is where your code is saved. If you right click on your project and click properties, in the resource section there is a spot labeled Location: The file path there is where that project is saved. (It will be under your workspace folder)
I'm working with LibGdx and Eclipse, I used the latest version and the setup tool that creates the project for Android, desktop and another one named "core", I imported in Eclipse, but I keep getting this error in both desktop and android projects:
The declared package "com.mygdx" does not match the expected package ""
Could you help me out please? Thanks in advanced!
Just in case someone might find it useful, the actual problem was to add numbers in the project's name, that's why the package was splitted after com.mygdx, then the separate folders were created and gave me errors. I deleted this project, created another without numbers and that did the trick.
Thanks a lot for the help, still learning this libgdx + gradle!
Right click on the src folder and select Build Path -> Use as Source Folder. Then restart Eclipse.
EDIT:
right click project -> Properties -> java Build Path -> Source -> Add Folder -> select src/
Basically eclipse is not able to descend your package tree correctly. After this refresh the project try a clean build.
I am going through the Android app tutorial here:
http://developer.android.com/training/basics/actionbar/styling.html
As part of what I am doing I added in the appcompat library as part of adding in the themes. Not sure how I got to this point but when I try to run the app I get the error :
"The container 'Android Dependencies' references non existing library 'D:\eclipse-bundle\sdk\extras\android\support\v7\appcompat\bin\android-support-v7-appcompat.jar'"
The library DOES exist, just not at this location. It is located at:
D:\eclipse-bundle\sdk\extras\android\support\v7\appcompat\libs\android-support-v7-appcompat.jar
There does not appear to be any way to edit this property. How do you fix this problem? what is causing it?
Thanks in advance for any help.
Make sure you follow this step to add .jar files.
In the new library project, expand the libs/ folder, right-click
each .jar file and select Build Path > Add to Build Path. For
example, when creating the the v7 appcompat project, add both the
android-support-v4.jar and android-support-v7-appcompat.jar files to
the build path.
I had the same issue so I CMD+Q'd Eclipse and re-opened it.... magically worked. I guess "turning it off an on again" works sometimes :D
You can select your project on eclipse, then right-click...
A menu should appear, you can click on "properties".
A flying screen should appear, you can click on "Java Build Path"
Another flying screen should appear, you can click on the tab "Libraries"
This tab actually hold references to what is in the "libs" folder, and you can delete your old lib and insert your new lib (with the correct path) there.
Would not recommend any of it, actually... Please just import the "support lib project" into your eclipse workspace and make your project reference the imported project as a "lib project".
That is way more handy, and will actually give you a better flexibility for doing more stuff with compatibility lib.
And also, since it is on your workspace, you are the one that compiles it. No future lib reference problems \o/
I have just got a new computer and installed Eclipse Indigo and all of the plugins that I use. But when I open my workspace from my old computer some projects have an exclamation mark.
What does a red exclamation mark mean on a project folder?
The red exclamation mark usually means there is a problem with the Build Path.
Do you see any alerts in the "Problem" View?
It means that there is an error on that project..
You can look at all the errors in the Problems tab. press ALT SHIFT Q followed by X to
show this tab.
It means that there are two things happened.........
What ever jar file or project setup jar file for your application
are not located at that point where it was earlier in your computer.
So that First you have to setup your project with all the jar files
and refresh it.
Check syntax in your project might be some mistake in that.
The red exclamation mark in eclipse is because of the problem/issue with the build path.
To find the specific issue look at the problems tab of the eclipse.
Window -> Show View -> Problems (or) Alt+Shift+Q,X
If you didn't find any error on the project files, usually it means your build path has some issue. First Check your jar file and jar file locations.
On eclispe, right click on your project, Go to build path and go to Configure build path. Check any errors under libraries. Configure it correctly and refresh the project.
It appears mostly because of "build path" only. But just in case you are working on a MAVEN project, here is the solution.
Solution
Step 1. Expand your project in Eclipse > Right click on "JRE System Library" > "Build Path" > "Remove From Build path"
Step 2. Expand your project in Eclipse > Right click on "Maven Dependencies" > "Build Path" > "Remove From Build path"
Step 3. Reach out to your local repository and follow below path "C:\Users\userName\.m2\repository" and delete everything inside repository folder
Step 4. Refresh your project in Eclipse
Step 5. Right Click on your project > "Maven" > "Update Project"
Step 6. Just refresh your project and now we are Ready to GO..
In my case show hidden files was enabled and i had added hidden jar file extensions along with the original jars. Adding only the jar files except the hidden files solved the problem
It can appear when any other file other than .jar is added in the jar library. To fix this, remove the file and clean the project.
If it is maven project and your project view having no error. Then try the following steps
Right click the project ---> maven --> update maven
It works for me.
What the error means is that the Java (JDK) version installed needs an update, as the older version could not be read. To rectify the issue, uninstall your Java (JDK) and install the latest version. Restart eclipse and the would be seen resolved.
This may help in case your build path is correct and you have put the right signature and access specifier for main, so maybe used as a hook to try before you make any modifications to your build path.
Just go to your problems bar and delete the problem given for the project, clean the project and build it. It should solve the problem, if these steps cause the red exclamation to go away.
