Maven project appearing as path - eclipse

I have 3 Maven projects, but the 3th is appearing like a path in Eclipse. How do I set to Eclipse understand that Project 3 is a Maven Project, not a path?
EDIT: This occurred after I switch for other branch at GitLab

I solved this by clicking on Project3 with the right button of the mouse, click on Import, select Existing Maven Projects, select my project and Finish.
EDIT: you can also select Import as project

Maven Plugin Error in Eclipse oxygen

Can anyone help me with this?
Could not calculate build plan: Plugin
org.apache.maven.plugins:maven-resources-plugin:2.6 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-resources-plugin:jar:2.6
I tried the following ways:
Right click on project. Go to 'Maven' and click on update project. Click on OK.
Close the project in Eclipse. Delete the project in Eclipse ( but not the contents ). Navigate to the project in file system and delete .classpath and .project files. Go back to Eclipse and import the project as "existing maven project".
Please suggest.

Automatically update a maven project under eclipse, after a svn-checkout

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 didnĀ“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.

How to checkout maven project from svn repository

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.
