Read emails from imap using Spring integration is not working

Question

I am trying an example. In the example it is mentioned like use spring-integration 2.0.3, but I got a NullPointerExcpetion and to resolve it I followed what is mentioned here. But if I use spring-integration 2.1 then I think it requires spring 3.0.

Question: Is it possible to have Spring version 2.5 and have spring-integration using that read emails from imap?

The following are the maven dependencies set in my project:

<dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring</artifactId>
        <version>2.5.6</version>
    </dependency>
...
<dependency>
<groupId>org.springframework.integration</groupId>
<artifactId>spring-integration-core</artifactId>
<version>2.1.3.RELEASE</version>
</dependency>
<dependency>
    <groupId>org.springframework.integration</groupId>
    <artifactId>spring-integration-mail</artifactId>
    <version>2.1.3.RELEASE</version>
</dependency>

I didn't find a simple Spring Integration --> Spring version table. Here's what you could do:

go to https://repository.jboss.org/nexus/index.html#nexus-search;quick~spring-integration-core
pick any version
go to the 'Maven Dependency' tab in lower right container
click the 'Resolve' link

You'll see immediately which Spring version is required. For example with Spring Integration 2.0.0 you'll see that it depends on Spring 3.0.5.
