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

Answer 1

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.

I tried adding this jar but I still get the same error, was it all you needed to fix it? – Bedding

@Bedding you might have another version of httpclient somewhere in your classpath. – Mccown

@LizBennett yes, in the end that was the problem the older versions where on the webapp folder in tomcat – Bedding

Didn't work for me. I took out my http core and http client libs and it still wouldn't fly. I'm also using apache http fluent client, Maybe that's pulling in an incompatible version. – Perilune

Thank you. Migrating from httpclient-4.5.13.jar to httpclient-4.5.2.jar fixed the issue for me. – Ruthy

Answer 2

Look at the compile dependencies at maven repo for aws-java-sdk-core

You can see it's dependent on org.apache.httpcomponents » httpclient -- 4.5.2. Further check if you've all the dependencies of httpclient-4.5.2. You might be missing correct version of httpcore
