Prestashop 1.6, conflict: 2 different modules requiring same class, different versions

[Juan Bautista]

In my Prestashop project, I have several modules. In one of them (let's call it "AWS") I installed AWS SDK using composer (in PHPStorm), as explained here. Composer has "required", among other libraries, "guzzlehttp", updated to its final version.

On the other hand, there is another module (let's call it "orangeConnect") with composer too, that has an earlier version of "guzzlehttp".

The problem lies when I am using AWS SDK in php, inside a php script in the first module. What happens is that it tries to call the URI Composer class and it crashes. Actually, because of the inexistence of one class "UriResolver". The thing is that if I remove "orangeConnect" then AWS SDK connect correctly, which means that the class Uri, in "AWS" is not taken correctly because of "orangeConnect" module. However, I need imperatively to support "orangeConnect" in the project.

How can I, in summary, solve this conflict between classes in PHP inside Prestashop and allow each module to include the corresponding valid version of guzzleHttp without conflicts of any kind?

Thank you.
