How to check out multiple maven projects from remote git repository - eclipse

after a couple of hours trying and reading a number of tutorials, I can't fix the following problem: I have a remote server running a git repository. From eclipse (neon.2 and egit) I pushed several maven projects, each with its own pom.xml to this repository. When a friend of mine, who wants to co-develop tries to setup his environment, also using Eclipse Neon.2 and egit, we are not able to reproduce the setup in the Package Explorer. We get all the sources but in one project. The original maven projects are all nested in this one project. This wrong setup results in a couple of problems when trying to compile or run the projects.
We used File-> Import-> Git-> Projects from Git-> Clone URI. In Source Git Repository we pointed the Repository path to /home/git/workspace.git. In the Branch Selection dialog we can then only see the master. In the following Local Destination dialog we checked the Clone submodules checkbox. We played around with the following options to run wizards which were all failing, so we ended up with this one project option in the bottom of the three options in the dialog.
What is not happening, is the import projects dialog as explained here https://wiki.eclipse.org/EGit/User_Guide/Remote#Import_Projects
(but this seems to be a former version, since the Clone submodules checkbox is missing in the dialog before on this web page)
Can anybody please tell us how to extract the maven projects as top elements in eclipse, linked to the existing git repository, such that we can work as a team?
Should you need any additional information, please let me know.
Thank you in advance.

I would advise you to always put all Eclipse configuration files to the repository when creating projects. What you should do is add all necessary maven integration related files to the repository (.project, .classpath, .settings/*m2e.core.prefs or better yet entire .settings). If you have done so, you are fine. If not, add them and pull changes on your colleague's machine.
On target machine remove the project from workspace, but do not delete contents. In Eclipse Git repositories view select your repository and expand to see Working tree. Right click it and select Import projects. This will trigger the flow you pointed our at Eclipse wiki. From there it should be straightforward - Eclipse will try to detect projects and will import them, so that they have Maven nature and are managed by EGit.
If you don't want to or cannot share maven configuration in the repository, have a look at this answer which tries to describe how to achieve that without Eclipse configuration files.

Git hub project _ Learning)

I am working on a simple project to learn github. After I worked on my project in eclipse on my local computer, I pushed my project to github for other teammates. A second member of my team pulled this project from github and pushed back to github after making some changes. Now this morning I want to pull this updated project from github to my local machine (eclipse) so I can work on this updated project.
How can I pull this updated project from github to direct into eclipse on my local computer .
I am tried to do:
"git clone http://github.com/testproject/gitDemo.git" but it is not directly going to eclipse. If I save this project on my machine and then try to import into eclipse I got error message, "can not import, there is already one project exist with same name".
I did not see pull option in eclipse under:
Right click on project - team - Pull
Any suggestions??
Thank you in advance for all your help
I'll make one point that I'm not certain you do NOT understand, but as I often see this misunderstood, I'll point it out.
You should separate the notion of "git repository" and "project". When you clone a git repository from github (or bitbucket, or some central repository), you should store it in a directory tree outside of your Eclipse workspace. You then should right-click on the repository and select "Import..." to create a project from the contents of that repository.
Related to that, you should look for the "Pull" operation on the repository entry, not the project. I recommend to display the Git Repositories view on the left side, below the Package/Project Explorer, and make sure that you attempt all git operations in that view, instead of the Package Explorer view.
The only detail from your original post that I can address is the error about already having a project with that name. That error message is not ambiguous at all. You already had a project with that name. I have no idea whether that project was a copy of the repository that you had somehow already imported, or whether it's an empty project, or what. You don't provide any information about that.

Exporting project to Git in Eclipse vs IntelliJ

I am new to Git and was exploring the Git integration in Eclipse, IntelliJ, and Pycharm. In Eclipse, the way projects get exported seems to be that the project gets added to an existing repo, while in IntelliJ and PyCharm, the project's root directory itself becomes a Git repo. This approach made the most sense to me, but then again I don't have much experience in sharing code. This latter approach is also possible in Eclipse by clicking the "Use or create repository in parent folder of project" checkbox, but when I did so, Eclipse told me that using the parent folder was not recommended.
Now for my question: Why does Eclipse warn against doing precisely what JetBrains IDE's do by default? What are the dangers in using a project's parent folder as a Git repo?
I read online that it has to do with the fact that once the parent folder is created as a repo, you can't add any new projects to the repo. But what are the benefits of adding projects to existing repos vs just making a separate repo for each project to keep everything separate?

Connect existing Eclipse project to existing Git repository

I have an Eclipse workspace in ~/EclipseWorkspaces/Sabia with a number of projects under Ubuntu 15.10. The source code for these projects resides in a Git repository at ~/GitRepositories/Sabia.
I can find no way to tell Eclipse in the Pydev Package Explorer that the projects use the Git Repository. If I try to use Team->Share, the system rejects the Git repository because a directory for each project exists in the repository and Eclipse is trying to move the project to the repository which already has a project directory.
I tried the suggestion by Michal Grzejszczak but unfortunately it does not work because the Git Repository does not contain complete projects, only the source trees for the projects. The Eclipse metadata is in /EclipseWorkspaces, not in the Git Repository so import projects on the Git Repository perspective does not work.
In addition when I tried to delete the projects I got the following error message:
AppFrame (One of my projects) contains resources that are not in sync with /home/jonathan/Dropbox/EclipseWorkspaces/Sabia/AppFrame. Press 'Continue' to force delete`
for half of my projects.
Unfortunately the message gives no more information and I have no idea what kind of problem might actually exist. I am not prepared to delete any flawed projects until I have corrected whatever was wrong.
How can I tell the Eclipse Pydev Package Explorer where the Git repository resides?
You need to first add this repository to Git repositories view in Eclipse. Then remove these project from workspace, but without deleting contents and then the most crucial part import them back with "Import projects..." from context menu after right clicking Working tree of the repo in Git repositories view.
That should make your projects managed by Git.

Can't pull a Gradle project in Eclipse

I'm part of a team working on a game project and we just moved our project to using Gradle. I can pull, commit, merge and push normally with Git GUI in Windows Explorer, but other members of the team can also pull in Eclipse by right-clicking the Gradle-project folder in Project Explorer view, choosing Team-menu and then Pull. However, in my Eclipse the "Team" settings only give me options to "Apply Patch" and "Share Project.." the whole team has tried to find a solution for this to no avail so far.
Before the project was built on Gradle, I was also able to pull in Eclipse by using the aforementioned method. We're using Git repository.
Any suggestions on where to look for the cause of this malfunction?
Thank you.
I assume then you don't store the Eclipse project files/settings in your Git repository but create them locally using gradle eclipse.
Then after importing the project into Eclipse (be sure not to copy it to the workspace) you can use the Share project... option under Team in the context menu. Then choose Git. Eclipse EGit will automatically detect if your project resides in an existing repository (it should be listed on the next wizard page) and set up the corresponding association.
The term Share project maybe is a bit confusing, as you also do it for projects that already are under version control.

How to create Eclipse project with EGit clone

After spending a decade with SVN I've finally taken the plunge with Git. I have set up Git, Gitolite and GitLab on a server and have successfully added code to my local repository, committed, cloned repositories and pushed code back to repositories. So far, so good. Now enters EGit...
I have cloned a repository using the Git Repository Exploring view using the following syntax for the path:
ssh://dexter:vaultanalyser.git
(In GitLab, repositories are referred to as projects, so I assume that I am supposed to have one repository per Eclipse project? Rather than a SVN-style single parent repository that contains multiple projects?)
This imports the repository into:
/Users/mattpainter/git/vaultanalyser
I was expecting this step to automatically create an Eclipse project for me with all the source, but this isn't so. I tried fudging the target directory so it's in my workspace, but this isn't working either.
How do I get the cloned source available within Eclipse? This site implies that if you create a project with the same name as the repository, it all magically works, but this isn't the case (yes, I know the article is about Github, not GitLab, but I figured the two were close enough for the task at hand).
I've then tried creating a project in Eclipse and sharing it - but then the whole project appears as a sub-folder in the repository. If repositories are indeed analogous to projects, this isn't really what I want.
I've looked through other StackOverflow topics that look related, but I fear I'm still missing a key piece of understanding with how this is supposed to work and it's all looking remarkably convoluted thus far.
Help?
In GitLab, repositories are referred to as projects, so I assume that I am supposed to have one repository per Eclipse project?
Yes, but a GitLab "project" isn't necessarily an Eclipse one.
It doesn't have to follow an SVN structure, as illustrated in "Eclipse reference directory outside eclipse project directory but within repository".
All you need to do is to create an Eclipse project, specifying the source directory being not in the default path (Eclipse workspace), but wherever you cloned your repo (as described in "Getting started with Eclipse + EGit - confused").
That way, the eclipse project you just declared (and referenced in the Eclipse workspace) has its files (.project and .classpath) at the root of the Git repo.
And Egit can then manage that project just fine.
Or you can import it directly with Egit: "Eclipse + EGit: clone project into workspace".
As the OP nullpainter reports below:
The original issue was compounded by invalid permissions in the .git/objects folder on the server.
Running a chmod git:git -R * on the folder solved the issue
He details the right setup below.
To expand on #VonC's answer, the steps to get EGit and Eclipse to play nicely is:
Select 'Clone a Git repository' from EGit, accepting all defaults. This will create a folder in a git parent folder, somewhere outside your workspace.
Create a new Eclipse project. I'm using Java, but I assume there are similar steps for other languages. On the first dialog, untick 'Use default location' and instead select the repository folder created in step 1. Accept all defaults.
Select Team > Share Project... from your new project. Select Git, and tick the 'Use or create repository in parent folder of project'.
Now you can push your code and Eclipse dot files to your git repository from within Eclipse.
(My original issue was compounded by invalid permissions in the .git/objects folder on the server - running a chmod git:git -R * on the folder solved the issues)
I check it out with the command line - then build my projects on top of that. In fact, I end up doing most operations with command line git. EGit is useful for viewing the diffs but I find command line has more power and control. Git is mostly about giving devs lots of power and control.
