POM dependencies not working (Eclipse, Maven, POM)

Question

I have a project in Eclipse (Helios), with Maven pom.xml. My project is a web app that will use Hibernate, MySQL.

But i have endless woes in getting pom.xml right. I am new to maven, and can't believe setting up dependencies is so tough(do others have similar expierience / or am i dumb).

My pom.xml is here:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

All the above errors go away, if i remove the mysql dependency from the pom.xml file. I am totally confused why mysql should have dependency on these.

Isn't Maven supposed to resolve these dependencies automatically? Afterall isn't that the whole idea of using Maven.

Experts please guide me in the right direction.

Answer 1

You can search for dependencies here:

http://mvnrepository.com

For Maven2 it is:

http://repo1.maven.org/maven2/

Hibernate in particular is notoriously difficult for setting up the right dependencies.
