eclipse with new aws java web project, upgrade jar version

I'm not sure if I'm on the right track, but I can't find similar question on google or stackoverflow.

I'm using eclipse (luna), and I have this plugin from amazon, aws toolkit. When I create a project by clicking 'new aws web project', a new project will be created, and inside the aws sdk for java, some of the jar files have a version which is not I want, for example, spring-core-3.0.7.jar.

I tried convert this project to maven project and include dependency with latest spring-webmvc 4.x, but is seems two packages have conflict with each other.

I tried to delete or upgrade the jar from aws sdk for java, but I can't find a way to delete it or upgrade it.

Then, I tried to create a normal java web project, convert to maven project and include the aws-java-sdk-core from maven repository, but after that I can't use the deploy to elastic beanstalk function.

Actually, I just want to create a project which let me use the latest spring framework, and also able to deploy to aws elastic beanstalk.
