Tool does not write errors to stderr

[mlafeldt]

While working on https://github.com/mlafeldt/dotfiles/blob/master/bin/alicloud-assume-role, I noticed that the aliyun-cli tool does not write errors to stderr. Instead all output is written to stdout.

Proof:

$ aliyun sts AssumeRole >/dev/null

$ aliyun sts AssumeRole 2>/dev/null
ERROR: required parameters not assigned:
  --RoleArn
  --RoleSessionName

This makes scripting harder than it should be.

Thank you for your issue, this issue is a legacy of history and we are currently repairing it. We will reply under this issue after the repair.

Is there any update on when this issue might get fixed? It makes it annoying to debug issues in automation if this is not fixed.

We will release a version to fix it before 7.31.

$ go run main/main.go sts AssumeRole
ERROR: required parameters not assigned: 
  --RoleArn
  --RoleSessionName

use `aliyun sts AssumeRole --help` to get more information
exit status 3
$ go run main/main.go sts AssumeRole 2>/dev/null

After #373 merged and release new CLI, this issue will be fixed.
