I wish to create a multimodule maven project from SCM, my svn repository is DEVEO.
Here are the steps i perform in eclipse mars (I have installed m2e plugin + subversive + and required connectors)
Right Click Project Explorer > New > Project
Maven > Checkout Maven Project from SCM
SCM URL :
Click Next
Click Finish
Then there is a popup window saying "No projects found, do you want to create project using new project wizard" I click "OK"
From New Project Wizard, I select Maven > Maven Project
And i create my new project.
When i go into my workspace what i see is
A. Project Folder is not created inside maven folder
B. The Maven folder has no trunk, branches or tags
Ideally project should be created inside Maven folder > trunk. Any Helps
It is better if you:
checkout manually your svn repo outside the Eclipse workspace (without Eclipse running)
make sure your multi-module projet is working (mvn clean install)
Then you can import that project into Eclipse (File/Import Maven project), and Eclipse should detect everything (maven + SVN)
Thanks All,
My purpose was to just use eclipse subversive plugin and not install any external svn client like tortoise. Its kind of a workaround but eventually you can do everything from eclipse. So here is what i did
a. I completely ignored the m2e way of creating project from scm as mentioned in my question.
I simply created a maven multi-module project structure. Right click the root project > Team > Share Project
and then while i am adding the project i use the option "use multiple projects layout with specified root name" and rest is very clear.
I even did not had to create a trunk or tag or branch in my repo separately. It was all done automatically.
I have a remote Mercurial repository containing Maven projects. I would like to clone it into my Eclipse workspace for development.
I currently have Maven Integration for Eclipse installed through Eclipse Marketplace. I also have MercurialEclipse. But I can't checkout the code as Maven projects. When I checkout normally, only the parent project code is fully downloaded which makes sense because the Maven nature is not identified.
I have svn integrated fine, and I have the plugin "Maven SCM Handler for Subclipse" so I can easily checkout the projects from svn as Maven projects. Is there something like this for Mercurial?
Also I checked "File->New->Other->Maven->Checkout Maven Projects from SCM", and I see only svn in the dropdown.
Please let me know if the Maven-Mercurial integration in eclipse is possible.
Thanks for looking into this.
I do that every day at work and there is a small trick for it.
Try to do it in this order:
clone the project from command line
then in eclipse import the project as a maven project
then right click on the project and select team->share->mercurial
follow the dialog boxes and eventually you will get to the one asking you the url of the scm.
And that's it.
For multiple module project, you might have to repeat steps 3 and 4 for each of them.
For info i am using the version 1.2.0 of the maven plugin and for the mercurial one i use the one from the new website: https://bitbucket.org/mercurialeclipse/main/wiki/Home
and configured with an external mercurial client.
You can clone and configure a multiple module project using MercurialEclipse and Maven plugins from Eclipse IDE performing the following steps.
Clone the project in Eclipse IDE using MercurialEclipse.
Right click on the cloned project in the Project Explorer, select "Configure" and then "Convert to Maven Project".
Select File, Import and "Existing Maven Project" and click Next. You will get your cloned project and modules automatically selected on the next screen, so just need to click Finish button.
Finally, you will get your multi module project cloned and configured as maven project.
I use MercurialEclipse plugin and do Checkout in other way:
Clone repository
File -> New -> Project...
Select Mercurial -> Clone Existing Mercurial Repository Next >
Type URL, Auth data, and Clone directory name (optional) Finish
Prepare project for Eclipse
Generate Eclipse files: execute mvn eclipse:eclipse in command line
Refresh project (via context menu or F5)
Sometimes in the end you need to select the right encoding:
Open Project properties
Set Resource -> Text file encoding to Other
I have checked in a maven multi module project.If I check in in normal way, as "import - svn Checkout projects from svn" , then the main project is checked in as one folder and it is possible to team -> sync with repositary.
But as the main project is a maven project with multiple modules in it, I tried "import - maven - checkout maven project from scm", selected svn from the drop down list and checked in.Project check in fine.Not only the parent folder, but it lays out all the modules seperately too so that we can work in them individually.The question is, I cant, team ->sync with repositary. That option is not available.
I got it. You have to right click on the project and give share project...
I have commited just the src folder and pom.xml of maven project into SVN repository in order to make it independent of IDE (As .settings, .project etc are files specific to eclipse ide)
Then when I'm trying to import the src folder in a newly created maven project (as it has the other files which are needed to run the project in eclipse), basically I only want to synchronize the src folder and pom.xml with the repository, I get a warning while I import the src folder 'as a folder in existing project' AS 'Destination project is detached from the source control. So please take into consideration that the plug-in won't provide any SVN actions for these resources' and then I'm not able to use Compare with and Team Options. It doesn't even show the revision no. besides the imported class files and folders.
Is there a way to do this ??
What is/are the usual industry practice/s ??
There're 2 options.
1.) Check out the SVN files using some other tool e.g. (TortoiseSVN) and then import the maven project using 'Materialize Maven Project'. This will create necessary metadata for eclipse and will also maintain the version info for the checked out project. See this reference http://www.sonatype.com/books/m2eclipse-book/reference/creating-sect-importing-projects.html
2.) The (better) other way is to download 'Maven SVN Integration' plugin using update site
http://m2eclipse.sonatype.org/sites/m2e-extras/. Once you install the plugin, you would be able to see option 'Check out as Maven Project' in SVN repository exploring perspective.

How can I get the effect of choosing to import from both Maven and Git and have Eclipse properly generate my project?
To get my project into Eclipse I can choose File->import->maven and then I get all the Maven projects imported and can build fine, or I can choose File->import->git and make a new project that ignores the pom.xml and does not generate the project properly.
It seems I can do one or the other but not combine both so I get a correctly generated project.
Eclipse Indigo + M2Eclipse 1.0 makes it very easy.
If you don't already have the Git connector for M2Eclipse install it. M2Eclipse will help you along by prompting you on the Import menu.
Select the "Import..." context menu from the Package Explorer view
Select "Check out Maven projects from SCM" option under the Maven category
On the window that is presented choose the link "Find more SCM connectors in the m2e Marketplace
Find connector for Git...install...restart
Note that in the search box you may have to enter "EGit" instead of "Git" to find the right connector.
With that done, simply go to the EGit repository, bring up the context menu for the Working directory and select "Import Maven projects...".
Done!
I would perform a git clone via the command line (outside Eclipse) then use File -> Import... -> Existing Maven Projects.
Your projects will be understood as using Git and Maven. It's the fastest and most reliable way to import IMO.
Step 1 : Setting Up Eclipse
First of all you'll need to have a few Eclipse plug-ins installed. So use eclipse IDE software install feature in the help dropdown menu → Install new software, and add link to Available Software Site, then install it.
GIT plugin (EGIT)- http://download.eclipse.org/egit/updates
Eclipse Maven plugin (M2Eclipse) - http://download.eclipse.org/technology/m2e/releases
Maven SCM Handler for EGit (m2e-egit)
Install from the M2E Marketplace (Settings → Maven → Discovery → Open Catalog and search for " m2e-egit")
Step 2 : Clone the repository
Clone(download) your Maven Projects from Git
Check out non-eclipse Maven Projects from Git (File → Import.. → Maven → Check out Maven Projects from SCM)
Now add your git repository link to SCM URI field.Then click next & finish.
As of this (updated) writing, a working setup is the following:
Eclipse 3.8 (Eclipse Indigo update site)
EGit 1.3.0 (Eclipse Indigo update site)
m2e 1.0.200 (Eclipse Indigo update site)
m2e-egit 0.14.0 (m2e marketplace when adding a connector)
Tested on Ubuntu Raring.
You can certainly "Import" -> "Maven" -> "Check out Maven Projects from SCM", and this is the quickest way. However, such direct import currently does not give you control over the cloned repository folder name. You may be better off working from the "Git Repository" View and perform either a "Clone from a Git Repository and add the clone to this view", followed by an "Import Maven Projects" from such clone; the longest way would be to do your manual cloning and then "Add an existing local Git Repository to this view", followed again by an "Import Maven Projects". Either case you have full control on the cloned folder.
A final comment on a side issue that made me cry in frustration. As far as I know, if the cloned repository lies on the root of your Eclipse workspace, and your Maven project file hierarchy has a POM on its root, then importing such root project will rename the cloned folder (with the template you chose, defaults to [artifactId]). Without changing your project structure and without keeping files outside your workspace, you can easily work around this issue by cloning on a subsubfolder of the workspace folder.
I have been testing this out for my project.
Eclispe Indigo
"Help > Install New Software" Enable/Install official Git plug-ins at "Eclipse Git Plugin .." and install the lot.
Enable the Maven/EGit connector with these instructions How do you get git integration working with m2eclipse?
Switch to the Git Repository perspective. Right click paste the project git url. The defaults should all work. You may want to change the install folder it guesses.
Expand the cloned repository and right click on "Working Tree" and pick "Import Maven Projects...".
Switch to the Java perspective. Right click on the project and choose "Team > Share Project". Select "Git" and be sure to tick the box "Use or create repository in parent folder of project".
Here's my workaround, this is a solution to these issues:
You can't install m2e-egit (I get an error in Juno)
Converting a general project (connected to your Git repository) to a Maven project isn't working for you (The Import Maven Projects step seems essential)
Importing Maven Projects from your repository on the filesystem isn't showing the project connected to Git.
Setup your Git repository in the Git Repository Exploring perspective.
Switch to the Java perspective, Import > Existing Maven Projects
Browse to your Git checkout in the filesystem, select the directory containing the pom.xml file. Finish the import;
you'll notice these projects aren't connected to Git. :-(
Delete these projects, but DO NOT DELETE FROM FILESYSTEM.
We don't want our clone deleted; this task also leaves the .project file behind so that we can import in the next step.
Go back to the Git Repository Exploring perspective.
Right-click your repository, Import Projects...
Select Import existing projects
In the explorer below, browse to and select the directory containing the pom.xml (and .project file) , then click next.
Continue through the wizard.
Import without installing any additional connectors for Mylyn:
Open Git Repositories view (Window->Show view->Git Repositories)
Press Clone a Git Repository button and proceed with all steps
In newly created repository expand Working Directory, right click on folder with your project and select Import Projects. Then either choose Import existing projects, or select Import as general project. If needed after importing right click on your project and select Configure->Convert to Maven Project (and Maven->Update Project).
You should note that putting generated metadata under version control (let it be git or any other scm), is not a very good idea if there are more than one developer working on the codebase. Two developers may have a totally different project or classpath setup. Just as a heads up in case you intends to share the code at some time...
I have a maven project with three submodules that is managed in git. I set them up in eclipse as follows:
I registered the git repository with eclipse using EGit
I imported the projects as existing Maven Projects
For each project, I went Team | Share Project.
Direct answer: Go to Files>>Import>>Git>>Project From Git (you should have GIT installed on Eclips)
I would prefer to import projects into Eclipse as maven projects rather than git project. Doing this will still allow the project contents to be recognized as git contents. You can continue to perform git operations from Eclipse. As you have mentioned the reverse is not true.
The nature of a project in Eclipse is not based on the SCM which holds the project, but on the type of project - whether war or jar, etc. - which is automagically determined when the project is imported as maven project.
I would be hesitant to check-in to SCM IDE-specific metadata. Doing so assumes a lot of things - all developers are using the same IDE or version of the IDE, perhaps same version of JDK/JRE, that they continue to use the same version throughout the project lifecycle and so on.
Can't you import it as a git project and then (if you have the m2eclipse installed) right click on the project in the Package Explorer > Maven > Enable Dependency Management?
After checking out my branch in Egit, I switched to the Java View, then used File-->Import, Git-->Projects from Git, then selected the top level maven directory. This was with Eclipse Kepler.
Instead of constantly generating project metadata via import->maven command, you can generate your project metadata once and the place it in your git repository along with the rest of your source code. After than, using import->git command will import a proper maven-enabled project, assuming you have maven tools installed.
Make sure to place into the source control system all files in project dir that start with '.' such as .classpath and .project along with the entire contents of the .settings directory.
