sam build -u vs sam Build -u -b directory structure #1284

Closed viksrivat closed 5 years ago

viksrivat commented 5 years ago

Description

Running sam build -u -b folder creates a nested directory structure that is not shown when running sam build. This will not block deployment or anything, but could be a cause for potential bugs when SAM-CLI updates sam build.

Steps to reproduce

The example below is a slightly modified version of the sam init --runtime python3.6 hello world app that use 3 functions instead of 1 in order to display the bug. template.yaml:

AWSTemplateFormatVersion: '2010-09-09'
Transform: AWS::Serverless-2016-10-31

  sam-app

sam build -b folder -u should create the same structure as sam build -u

Additional environment details (Ex: Windows, Mac, Amazon Linux etc)

  1. OS: Mac
  2. sam --version: SAM CLI, version 0.18.0

Fixed by moving python code to a new folder instead of using "."
