Azure-pipelines-tasks: cURL Upload Files task does not support SFTP

[ThomasBarnekow]

Environment

• Server: Azure Pipelines
• Account name: dokumate
• Project name: DokuMate
• Release Pipeline: Deploy DokuMate for Office
• Agent: Hosted VS2017

Issue Description

I need to upload files via SFTP, so I tried the "cURL Upload Files" task, because the description says that it supports SFTP. However, as shown in the log below, "sftp" is not supported or disabled in libcurl.

I tried the the curl command in my git bash locally and it worked. This looked something like this:

curl -k -u user:password -T filename sftp://HOST.sftp.wpengine.com:2222/path/to/folder/

Expected Behavior

I would obviously expect the cURL Upload Files task to support SFTP as advertised.

@ThomasBarnekow Unfortunately the version of cURL installed on the agents does not support SFTP, so the task description is incorrect. On the Windows agents, the latest version of git bash is used and that is packaged with a version of cURL that does not support SFTP.
The task uses whatever version of cURL is on the machine, so if you need SFTP support you can create a task/script to download whichever version of cURL that you need and then just set the PATH properly and the task will work.

Sorry for the misleading task description, it will be updated.

@joshmgross Thanks. In the meantime, I created my own Node-based Azure DevOps extension with an SFTP upload task that, in my own tests, is much faster than cURL. This is based on the ssh2-sftp-client npm package, which in turn depends on ssh2.

@ThomasBarnekow Glad you got this worked out and in a faster way than cURL. Closing this issue.
