I am new to Maven and Eclipse, I need to check out an existing Maven project from a SVN repository. I have installed the M2E plugin and the subversion plugin and they seem to be working properly. Here are the Installation Details -->
When I right click in the project explorer and select Import -> SVN -> Project from SVN, then select the repository location and click finish, I am prompted with 4 possibilities
What is the procedure for checking out a Maven Project from this point on, or am I on the right track here?
Thanks for your help in advance!
tl;dr : Check out this video. The portion between 1:04 and 1:50 should answer your question (To skip to the interesting part, click on the youtube player and press 4).
You already have the SVN connector for m2e installed. Thus it should be possible to Import Existing Maven Project from the SVN repository.
From the options you have listed in the above snapshot, you should be able to proceed after selecting the First or the Fourth option i.e. :
(according to Mauno V's suggestion below) To convert this imported project into a Maven project Right Click on it and do a Configure -> Convert to a Maven Project like so :
If you have Pom project as a root branch, after project checkout completed, you may do it with import project as 'Existing Maven Project' and set the project as root project, and finish!
you should be able to see your module define as project in eclipse project explore, and eclipse will recognized as module project.
do right-click on Pom project, Maven -> Update Project or Alt+f5 to refresh and see the content project.

The .factorypath file is a generated file, which eclipse requires for annotation-processing. The m2eclipse plugin does generate this file when using "Update Maven Project" (Alt+F5) and checking "Update project configuration from pom.xml".
However, I don't want to check this file into version control. But if not, and someone from the team does a fresh checkout, and imports the project in eclipse, the .factorypath does not get generated until the "Update Maven Project" is performed manually. I don't want this manual step when a project gets imported, this has to happen automatically. Is there an option, that a project has to be updated upon import?
Since this is an IDE related question, and you seem to be using Eclipse IDE:
Menu Window > Preferences > Maven > Automatically update Maven projects configuration .
This will make it for you on project import so you would not need that manual step anymore.
Assuming your real issue is
I don't want to check this file into version control.
Though you have not specified which version control you are using but if you are a GIT or SVN user, you need to add files/directories pattern in GIT ignore file or SVN ignore properties.

I'm trying to import a Java project from my teams subversion repository. So I go through the import GUI for subversion, select my repository and the project, then choose to check it out as a project into the workspace.
However, the project now appears in my workspace simply as a folder:
Trying to add a new class tells me "source folder is not a java project". Is there something I am missing? Thanks.
Check out as a project only does what you want if you have checked-in the Eclipse .project, .classpath files etc. In that scenario those files get checked out and configure the Eclipse project. Otherwise you are just getting an Eclipse "Simple Project" which does not have the Java tools configured.
I assume you do not have those Eclipse files in your repository, so you want to use the other option that lets you run the Eclipse Create Project wizard as part of the checkout. This lets you choose the project type and setup some of the configuration. You can skip most of the configuration since you can also do that after the checkout finishes if you prefer.

After checking out a maven project from a svn-repository, eclipse shows dependency-errors.
To solve the problem,
I have to right-click on the project-folder,
then I have to click Maven --> Update Project
After doing that, the dependendicies of the pom-file are downloaded and the specific classpathes are set.
The problem: I have to do this everytime after a checkout of a maven-project.
My question: Why should I have to update manually the maven-project? Why didn´t do this the maven-builder automatically? Is there any way to engage eclipse or the maven-builder to do this automatically?
If you have Subversive (installable via the Marketplace), you can checkout and set up the project in one step from Eclipse. In the dialog File -> Import try the entry Maven -> Check out Maven Projects from SVN.
Unfortunately, maven project configurations tend to get stale when you're changing stuff in the POM. Another tip from me is use the keyboard shortcut for "Update Project" (Alt-F5 on Mac & Windows) which should select the project you're currently in and has the option to update all projects at once.
I checked out a Maven project folder from SVN. It is coming up as folders in the Package Explorer, and when I right click -> Build Path -> no actions available.
Is there anyway to add the source folder to appear as a package?
The project is not set up as an Java or Maven project inside Eclipse. You can apply the Maven and Java nature afterwards in the project properties, you could run mvn eclipse:eclipse outside of Eclipse and import the created Eclipse project into your workspace (it could even exist as option in the project's context menu under "Maven", depending on how the project is setup right now).
Or, much easier, you just checkout a Maven project from SVN. Within the "New Project..." dialog there should be an option "Maven > Check Out Maven Projects from SVN". Then it will be configured automatically.
I am struggling with maven in Eclipse even though I have m2e.
I checked out a maven project from CVS and cannot navigate anywhere. If I try References > Project, I get a pop up saying:
"Problems opening an editor Reason: services does not exist".
services is the name of the main project, which has sub projects within it. It all builds successfully so I am not sure why Eclipse does not work.
I suspect something related to classpath but have no idea how to edit it since it is not available from the project's properties. I actually tried to manually create a .classpath file but it did not help.
I also converted the project to a maven project but that did not help either.
Any ideas? I am using Eclipse JUNO.
I figured out my issue. I had to check out the project from CVS. Then (that's the important part), perform a maven import of an existing project within eclipse. That created maven "ready" projects where I could use all of the IDE's functionality.
Yes, you're right. If you import directly from a repository, hovering, linking and opening declarations isn't gonna work. Your solution is right, although another one more direct is use the "File->New->Other->Maven->Checkout Maven Projects from SCM". If then, you have problems because you can't select any SCM type, check Checkout Maven project from SCM - no connectors. If with connectors installed you still have problems: http://forum.springsource.org/showthread.php?102665-SCM-types-not-available-in-Checkout-Maven-Projects-from-SCM.
If you have checked out project from svn, project checked out is not generally a eclipse project thats why general functionality of eclipse does not work for the same.
To achieve the same functionality of eclipse like eclipse reader and all other shortcuts,we have to convert the checked out project to eclipse project.
Steps to Convert checked out project to eclipse project:
Right Click on Checked-out Project.
Point to Configure.
Click on Convert to Maven Project.(if checked out project is maven project)
These steps will convert the project to Maven project.
All the eclipse functionality will work for the same.
In addition to ensuring that the projects are configured as Maven projects, you may also go to Project Properties (right-click on the project in Package explorer) > Project References, and add projects in the workspace that the selected project may have references to.
I had this problem, too.
It looks like after a search-in-workspace Eclipse opened a wrong file.
I pressed Strl+Shift+H (Open Type in Hierarchy), typed in the class name, and opened it. The file opened in a new tab, and everything was navigable again.
The difference in icons is:
