メモです。
主に、依存関係で既存のライブラリとの競合に気を付けないといけない。
ここまでのまとめ:
- WindowsローカルのAWS SDKでJavaプログラムを動かすまで
- AWS SDK for Java 1.11.x と 2.x

Looks like we are running into a dependency issue with Apache Http Client. See release notes for version 4.4.9:
4.4.4 は既にあったのだが、4.4.11 に変更したところ解消。
The Apache HttpComponents™ project is responsible for creating and maintaining a toolset of low level Java components focused on HTTP and associated protocols.
This project functions under the Apache Software Foundation (http://www.apache.org), and is part of a larger community of developers and users.
HttpCore is a set of low level HTTP transport components that can be used to build custom client and server side HTTP services with a minimal footprint. HttpCore supports two I/O models: blocking I/O model based on the classic Java I/O and non-blocking, event driven I/O model based on Java NIO.
