I'm new to Maven and use Eclipse Juno. I've installed Maven Integration for Eclipse. There are three options in File > New > Other > Maven:
1. Checkout Maven Projects from SCM
2. Maven Module
3. Maven Project
But I don't see Maven2 POM as described here. I've read that adding pom.xml is the first thing to do when using Maven.
I have an existing Dynamic Web Project so I'm not sure whether I need to create Maven Project just to use Maven.
How to use Maven with this existing project?
Further, when I try to add Maven Project and on step "Select an Archetype", then all shown archetypes have version "RELEASE". When I click Next on this step, Eclipse becomes Not Responding. It's used memory doesn't even increase.
Take a look here :
- http://www.mkyong.com/maven/how-to-convert-java-web-project-to-maven-project for a manuel convertion.
- Convert Existing Eclipse Project to Maven Project
In last version of eclipse (Juno included), there is a more convinient wizard :
Configure > Convert to maven project
You need to import the project as a Maven project.
File -> Import -> Maven -> Import existing Maven project.
