What version of httpclient is compatible with the Amazon SDK v 1.11.5?

Question

I’m using the Amazon Java SDK, version 1.11.5 (I included the aws-java-sdk-1.11.5.jar in my WEB-INF/lib directory). What version of the Apache httpclient library do I need to include that is compatible with this version of the AWS SDK? I tried httpclient-4.3.4.jar, but I get the below error

Looking at the source for the Java AWS SDK, under tag 1.11.5, you can see the in the POM file they have specified the following:

<httpcomponents.httpclient.version>4.5.2</httpcomponents.httpclient.version>

So I'd say HTTP Client version 4.5.2 is compatible with the AWS SDK version 1.11.5. If you are using a dependency management tool like Maven you could always just let it pull in the version of HTTP Client specified the the AWS SDK.
