[Tyriar]

That specific tasks is working correctly imo:

However, wrapping the the echo arg in quotes like this:

    {
      "label": "echo",
      "type": "shell",
      "command": "bash",
      "args": [
          "-c",
          "echo '${workspaceFolder}'"
      ]
  }

Results in no output. And using "echo \"${workspaceFolder}\"" still ends up stripping the \ again. There may be a problem in escaping the command line?

Also fwiw this task is overly complicated since it’s running bash inside cmd, you could just run bash directly which ends up working correctly:

    {
      "label": "echo",
      "type": "process",
      "command": "bash",
      "args": [
          "-c",
          "echo \"${workspaceFolder}\""
      ]
    }

It’s not entirely clear whether we actually do have a bug here, but regardless I think @Andromelus should move to `“type”: “process”.

The type process part above should work, having type shell means it will run inside cmd.
