Opening existing project from source control - eclipse

I've been pushing my source to a Mercurial repository. Today I needed to delete my local copy and re-clone. I did this by simply moving my local copy somewhere else (just in case) and typing "hg clone url".
This part has worked just fine.
However, when I try to pull the newly cloned local copy into Eclipse, I get the following error:
/Users/Andrew/Dev/Workspace/Android/MyProject overlaps the location of another project: 'MyProject'
My guess is that I have been committing some meta file or something that I shouldn't have. Does anyone have any ideas? Here is my .hgignore:
syntax: regexp
\.DS_Store
.swo
.swp
.metadata/
/bin/
Note: Looks like my hgignore is not blocking the gen folder. Could this be part of the problem?

There is a bug in Eclipse what won't let you create an Android project from existing sources:
http://code.google.com/p/android/issues/detail?id=8431
You have to move MyProject to a folder that doesn't have any other projects in its sub-directories. You can then make a new project from existing source with MyProject. Remove the new project from the workspace without deleting the contents on disk and move it back to your Android folder. Now do an Import -> General -> Existing Project into Workspace, and MyProject should be available to import.
This is the only way I've been able to do it.

Ok, I'll try to sum it up, after I faced similar problems and wasted some time:
Eclipse Juno /4.2 SR1
(however I think it is a general misunderstanding of how eclipse imports projects)
If you want your new project "connected" to git/mercurial, you'll have to clone and import via "Import/Git/Import from Git"
It will fail if your "workspace dir" equals the "local destination dir".
A git clone via egit MUST NOT be placed! in the "eclipse workspace dir"!
The project import will fail because the projectname in the cloned ".project file" already exists in the eclipse workspace dir when the import occurs.

I think the problem is that you moved your local copy away and then you try to add another project into Eclipse at the same location as what you had before and you are just confusing Eclipse...
I would recommend to try to use command line commands for Mercurial and when you get into Eclipse, first clean up existing projects before adding another one.

My sollution was just to import as general project not an android one.

I ran into this problem when trying to import a git repo project and it's submodules. I ended up using import -> git -> Projects from Git (git plugin). This understood the concept of a project within a project just fine. The project is now monitored by that plugin. It's a good enough tradeoff for me.

Target location for project " " already exists, can not move project

when I am trying to share my project with git repository getting exception like this
"Target location for project " " already exists, can not move project"
Writing an answer because I tried many options suggested in many similar questions but none worked. Then I did it manually with following steps that worked, and these steps will work for any Eclipse version:
Goto the Eclipse workspace in the file system and copy the project from there and paste it in some other location in your file system. This will serve as a backup.
Goto your Eclipse and then right click on the project and click delete. You can say delete from the file system because you've already taken a backup in step1.
Goto your Git repo in the file system and paste the project folder at the location you want (may be inside another folder with .project file doesn't matter).
Then come back to your Eclipse and then File->Import -> Import from Git -> Local repo -> Select the Git local repo where you've pasted the project in step 3 and then import it as usual.
As I said earlier, this will work for any Eclipse version.
This situation will happen if you already have a Project of the same name in your local git repository. Sharing a project means steps to commit your project into your local git repository and from there it as ORIGIN will be pushed to Master (Remote). (You are creating again with a new eclipse IDE, or that project was deleted from IDE but committed to local repository in the past).
Solution is simple:
Remove the project from your local git repository.
C:\Users\username\git on windows operating system. (If this not possible then next step)
Rename the project in your IDE (Better recreate a project with same code but with new Project name) that you want to share: repeat the process of sharing on Eclipse IDE.
You may optionally want to recreate after dropping the remote repository(master), if something is already pushed from last push of project, so that everything is clean. You may visit the git repository to confirm it.
In my case this was caused by an extraneous .project and related Eclipse files at the top of the git repository folder. The files were created by Eclipse due to incorrect folder specified on Import of the other projects in the repo.

spliting git repository from eclipse project - egit

I'm more or less a git newbie, trying to get a good Setup to work in Eclipse with egit. I'm running Kepler with latest updates.
Originally I Setup the structure inside the Workspace Directory.
+Workspace/.git
+Workspace/TheProject
Using this Setup (admittedly with Juno) commits were taking forever. For this and other reasons I'd like to move git outside the Workspace Directory, outside eclipse in a parallel Directory.
+OtherDirectory/.git
+Workspace/TheProject
But I'm not getting very far. There seems to be no easy way to split the EXISTING git to another Location without having the Project move there too(!?)
I've tried e.g. Cloning the existing git (in the git repository perspective) and having it Import the Project in the same move.
I've tried just Cloning the existing git, without selection of "Import Project" at the same time.
Then I right clicked the cloned repository and went through the Import Existing Project dialog. I don't get a Chance to say where the Project should be loaded to.
In both cases the Project Ends up in the same Directory as the .git Directory (now outside the Workspace)
+OtherDirectory/.git
+OtherDirectory/TheProject
and not as I wish - to have the Project in the Workspace Directory.
This must be possible (?), but how?
Simply copy the .classpath and .project from Workspace/TheProject or OtherDirectory/TheProject, to otherDirectory (where the .git folder is).
Then import your project into the workspace, as in "Eclipse - Import an existing project?"
Everything will remain in OtherDirectory/ (outside your Eclipse workspace folder), but will be visible in your Eclipse workspace.

Importing with EGit clones repository but doesn't let me import project

I just started my third repository on Github. I initialized the repository on the website with a README file and tried importing it into Eclipse with Egit. Like my other projects from Github, the import dialog worked fine and the repository was cloned. In my file explorer, I can see the folder Egit created, as well as the .git folder and the README from the repository.
However, when I get to the point where Eclipse wants me to choose a wizard for project import, everything stops working. I can't import an existing project, because none exists yet. If I try to import it as a general project, it doesn't let me go further because it claims:
/path/to/my/folder overlaps the location of another project: 'gnu_magic'
This is indeed the name of the project I'm trying to import, but as I just imported it for the first time that shouldn't be a problem.
If I use the new project wizard, it doesn't let me use the same folder name as the project, claiming that the folder is not empty (which is true, but strange when I'm using the wizard to create an entirely new project). If I give the folder another name, it creates a project but the project isn't connected to the repository - I have no way of committing my changes back to Github.
Deleting the gnu_magic folder and starting all over again brings the same results.
Is there a way to remove the metadata over that specific project from Eclipse's configuration? I don't want to lose my other projects but I would like to work with Egit on that project.
Another interesting fact: If I clone the repository manually and then try to import it into Eclipse, as a project from my file system, it doesn't let me becasue the source is in the heirarchy of the destination.
Or am I missing the point here completely? I'm just surprised that I was able to clone the other repositories without any problems. Working with them over the past few days has been quite easy.
The solution was a bit strange. Here's the steps to solve it:
Clone repository using EGit
Eclipse refuses to import project, claiming it already exists. Exit import dialog.
Create new project using existing code, using cloned repository
Share project with old repository
Now the project is once again connected to the repository. Be careful with this method because if something goes wrong you might commit over your old code. This solution works with Indigo and Juno.
I'm using Eclipse 4.2 Indigo, and I've been struggling with these same problems for a while now.
If you have already cloned a repository on your machine somewhere, using EGit or whatever, you can:
1) Create a new Eclipse project.
2) File -> Import -> General -> File System Choose the cloned repository location. This will import everything, including the .git folder within the repository, into your Eclipse project in your workspace. For this it doesn't matter whether there's .project files anywhere in the imported files or not.
3) Team -> Share Project -> Git The EGit plugin should detect the .git folder within your project and suggest settings accordingly. You will have a new local repository location addded to EGit's repositories which will point to the .git folder under your project's directory.

Eclipse + EGit: clone project into workspace

I'm a little confused about how EGit workes.
I have an existing git repository on Github and want to clone it into my workspace.
My goal is to have the local repository directly stored inside my workspace-folder but I don't get it working with EGit.
When I want to clone the github repo with EGit, I have to choose a directory as destination. The suggested directory is in my homedir (not in my workspace). When I choose this directory I can see the project in Eclipse but it is not stored in my workspace-folder. Instead it is stored in my home dir.
When I choose a directory directly inside my workspace, later when it comes to import the project it says that there is already a directory with this name.
I don't know how to solve this. I thought this would be a common scenario. In the past I have used hgEclipse (Mercurial) and it was working exactly the way I thought it should be so I'm confused EGit doesn't. Maybe I misunderstood something.
Probably this is important to know: In the github repository there are no .project or .settings files from eclipse. I have them on my .gitignore and so in the import-dialog I have to choose "Import as General Project" and not "Import Existing Projects". But I think this shouldn't matter?
I hope someone can help me or explain me why the EGit plugin doesn't clone the repository directly into the workspace by default.
My Eclipseversion is 3.6, I have installed EGit over the markedplace.
As mentioned in this EGit tutorial, the destination directory you mention when importing (cloning) a Git repo is any directory you want, in which the .git will be created:
You don't have to select the workspace itself (at least, you should select the workspace/myproject subdirectory, in order to not make the all Eclipse workspace a Git repo.
And you can select any other directory outside the workspace: the Eclipse workspace should only contain meta-data about Eclipse projects and settings.
When declaring a new project, you will be able to select the project directory, making that directory the parent for .classpath and .project.
Your workspace will list that new project, even though it lives outside the workspace.
To import a project from GitHub you should use the Import Git Repository as New Project dialogue (right click -> Import -> Git -> Git Repository as New Project). This way you can select the destination of the clone repository, including the Workspace.
If you want to edit the sources in the IDE and also want the changes to be reflected in the Git repository, delete the original source file in the project and link the source file in the git repo to the project. That way, you can directly make changes to the git repo and you can commit them when needed. Be careful not to delete the files when deleting the project in the IDE though.
Steps to have git project in workspace (with egit):
On GIT perspective choose "Clone a Git Repository and add it to this view"
As a destination choose folder inside a workspace (for example ".../workspace/myproject")
Wait until cloned
File -> New -> Project
General -> project
As a project name type name of a folder in workspace where project has been cloned (for example "myproject")
Nope. There's no way to get this to work. You can't use egit to checkout a git project into the workspace and if you check it out elsewhere and try to copy it into the workspace, you will lose your connection to the remote repository. If you want VCS that works, use svn or mercurial.
In the "Configure Local Storage Location" dialog,
choose .../workspace/projectname.
Then in the next dialog,
we get the wizard selection menu. Normally you should select "Import existing project".
(But see below).
Finally, there is the "Import Projects" dialog.
For various unexplained reasons, sometimes this dialog is empty and won't
let you finish. In that case, you need to cancel, and then outside of Eclipse completely delete the working directory that was cloned into, and then start again.
But if there is the project there, press finish. If it complains about the project already existing, go back to the wizard menu and change it to use a wizard. Select a Java wizard and then finish. Often this will work, but only if you first got the "Import Projects" menu to recognize the project in the first place.
It may take several attempts to get this to work! But once it is set up, it works fine.
So, in summary: is is possible to get EGit to use the default project location for the git clone, but in my experience it may inexplicably require several attempts.

How do I create a git repository over an eclipse project or vice versa?

I have a git repository that is just a directory tree (/myprogram/src/com/mycompany/test) with some source files. I wish to create an eclipse project around this repository. Both orders of create project in eclipse and git clone <url> <myprogram> from the command line give me a "folder already exists" error from whatever tool I use last. I could move the files manually to merge them, but it feels messy and I'm not 100% confident I know which files to touch.
How is this supposed to be done properly?
You could do it by selecting Import -> Existing Projects into Workspace, select the directory containing your project (the parent of myprgram), and check the checkbox next to your project (myprogram).
To have Git support in Eclipse, install eGit and then right-click your project, select Team -> Share Project -> Git, expand the triangle to select the existing repository and click Finish. This should give you Git annotations on your project.
Another option might be to just select Import -> Git -> Git Repository (after eGit is installed) and import your repository (but I've never done that with a local repository). See also the eGit user guide.
To resolve this I just ended up copying the git repository into a newly created project, but upon revisiting the issue I found a link here that suggests something slightly more elegant (but functionally similar).
After creating a new project, use Import -> Filesystem and Select All. In my case, my repository already had a proper /src/com/... directory structure which merged nicely into the one set up by the new eclipse project.
