scheduler/src/*.erl

scheduler/src/server_sup.erl
scheduler/src/server_app.erl

below works. ebin/server.app is generated correctly.

That's just how Erlang/OTP works. The application name must match the directory name. Not much I can do about that.

[pankajsoni19]

aws code build creates code under temporary directory. its difficult to rename that.

ex

make[1]: Leaving directory '/codebuild/output/src236792627/src/deps/base64url'

what would you suggest in that case?

[essen]

You can use multi-application layout so your application would be under apps/.
