Bug: option --base-dir does not work

[stationname]

Description:

--base-dir does not apply the given directory to relative path in --config-file

Steps to reproduce:

(1) project structure:

/ 
    my_lambda_project1
          build_and_deploy
                samconfig.toml
                template.yaml
    my_lambda_project2
          ...

(2) move to root directory (/)

(3) run sam build --base-dir "./my_lambda_project1" --config-file "./build_and_deploy/samconfig.toml"

Observed result:

2024-04-12 16:39:57,170 | Config file ./build_and_deploy/samconfig.toml does not exist or could not be   
read!                                                                                                         
Error: Config file ./build_and_deploy/samconfig.toml does not exist or could not be read!

Expected result:

sam starts building using the samconfig.toml file

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

• OS: Mac OS
• sam version: 1.115.0
• aws region: irrelevant for this use case.

sam --info:

{
  "version": "1.115.0",
  "system": {
    "python": "3.12.2",
    "os": "macOS-14.3.1-arm64-arm-64bit"
  },
  "additional_dependencies": {
    "docker_engine": "20.10.16",
    "aws_cdk": "2.61.1 (build d319d9c)",
    "terraform": "Not available"
  },
  "available_beta_feature_env_vars": [
    "SAM_CLI_BETA_FEATURES",
    "SAM_CLI_BETA_BUILD_PERFORMANCE",
    "SAM_CLI_BETA_TERRAFORM_SUPPORT",
    "SAM_CLI_BETA_RUST_CARGO_LAMBDA"
  ]
}

Hi, thanks for bringing up the issue. Can you try running the build again with the command with it like this and let me know your result then? sam build --base-dir "./my_lambda_project1" --config-file "build_and_deploy/samconfig.toml".
