The documentation implies that using --overwrite-mode=IgnoreIfExists should make the command return success if the package already exists with the same version number. However, it does not. The option is parsed correctly – if I use an invalid option like --overwrite-mode=fnord I get a syntax error from octo.exe – but it does not have the desired effect. Slightly cleaned example below.
PS D:\DEVOPS_AUTOMATION\Scripts\jobs> & .\octo.exe push --overwrite-mode=IgnoreIfExists --package $zipfilePath
