Question

I want to switch my java spring project to maven and start from simple srtucture. I have created archetype project and add subfolder with Service.java in main package. I describe dependencies but get an error:

maven Could not find artifact org.springframework:spring:jar:3.1.1 i central (http://repo.maven.apache.org/maven2)

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

Do you know why I can not dowload this package?

Answer 1

Your version and artifact ID are wrong, they should be:

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-core</artifactId>
    <version>3.1.2.RELEASE</version>
</dependency>

Note that since (AFAIR) Spring 3.0 there is no longer singel spring.jar – you must include spring-core.jar, spring-context.jar, spring-beans.jar and whatever you also need. You can find all of them in maven repository.
