Please describe the problem.

git-annex doesn't build if the aws dependency is version 0.17.1

This probably wasn't caught during your testing because the stack.yaml is currently set to use aws-0.16.

What steps will reproduce the problem?

cabal install with --flags=s3\ webapp

What version of git-annex are you using? On what operating system?

6.20171003 on macOS

Please provide any additional information below.

The error is

Have you had any luck using git-annex before? (Sometimes we get tired of reading bug reports all day and a lil' positive end note does wonders)

Yes! :)
