I want to import existing maven project into eclipse. I found 2 ways to do it, one is through running from command line mvn eclipse:eclipse and another is to install maven eclipse plugin from eclipse. What is the difference between the both and which one is preferable?

The maven-eclipse-plugin is a Maven plugin and has always been there (one of the first plugin available with Maven 1, one of the first plugin migrated to Maven 2). It has been during a long time the only decent way to ~~integrate~~import an existing maven project with Eclipse. Actually, it doesn't provide real integration, it just generates the .project and .classpath files (it has also WTP support) from a Maven project. I've used this plugin during years and was very happy with it (and very unsatisfied at this time by Eclipse plugins for Maven like m2eclipse).

The m2eclipse plugin is one of the Eclipse plugins for Maven. It's actually the first and most mature of the projects aimed at integrating Maven within the Eclipse IDE (this has not always been the case, it was not really usable ~2 years ago, see the feedback in Mevenide vs. M2Eclipse, Q for Eclipse/IAM). But, even if I do not use things like creating a Maven project from Eclipse or the POM editor or other fancy wizards, I have to say that this plugin is now totally usable, provides very smooth integration, has nice features... In other words, I finally switched to it :) I'd now recommend it to any user (advanced or beginners).

If I install maven eclipse plugin through the eclipse menu Help -> Install New Software, do I still need to modify my pom.xml to include the maven eclipse plugin in the plugins section?

This question is a bit confusing but the answer is no. With the m2eclipse plugin installed, just right-click the package explorer and Import... > Maven projects to import an existing maven project into Eclipse.

Using mvn eclipse eclipse will just generate general eclipse configuration files  this is fine if you have a simple project  but in case of a web-based project such as servlet jsp you need to manually add Java EE features to eclipse  WTP     To make the project runnable via eclipse servers portion  Configure Apache for Eclipse  Download and unzip Apache Tomcat somewhere  In Eclipse Windows -  Preferences -  Servers -  Runtime Environments add  Create local server   select your version of Tomcat  Next  Browse to the directory of the Tomcat you unzipped  click Finish   Window -  Show View -  Servers    Add the project to the server list

Since Eclipse Neon which contains Eclipse Maven Integration  m2e  1 7  the preferred way is one of the following ways    File   Projects from File System    - This works for Eclipse projects  containing the file  project  as well as for non-Eclipse projects that only contain the file pom xml  If importing from a Git repository  in the Git Repositories view right-click the repository node  one folder or multiple selected folders in the Working Tree and choose Import Projects     This opens the same dialog  but you don t have to select the directory

I was unable to import a Maven project with the steps suggested above until I figured out why it was not importing   A maven project will not import if you have another Maven project with the same artifact id  Make sure that your project s artifact ID is unique in your eclipse workspace
