h1. MAY Maven Eclipse Setup 

 h2. Install the Maven Eclipse Plugin 

 The Maven Eclipse Plugin, also named M2E, is available as part of the normal Eclipse distribution but must be explicitly installed. 

 Go to *Help* / *Install New Software...* and select the *All available site* in the drop-down list (it may take some time to load). 

 Expand the *Collaboration* category and select *m2e - Maven Integration for Eclipse*. 

 Click *Next*, finish the installation procedure and restart Eclipse when asked to. 

 h2. Convert an Existing Project to Maven 

 The first step is to convert your project into a Maven project. 
 To do this, right click on your project and on *Configure* / *Convert to Maven Project*. 

 You will be asked to create a new POM file. Just click *Finish* after editing the package, name and version if desired. 

 Alternatively, you can directly create a Maven project, this is out of scope of this document. 

 

 h2. Edit the POM File 

 Next, open the POM file in the project and edit it as follows, explanations are included as comments:
