I must admit I am not proficient in PowerShell, so it is hard to tell if it is AppVeyor bug or PowerShell that echo output is cached? For the following code the echo output is buffered until the whole block is executed. Is it intended and how to avoid that?

- ps: |-
    # powershell capture command output into variable
    $version = lxc version
    echo $version
     # pack lxc as aftifact for upload
     $archive = "lxc-$version-windows-amd64.zip"
     7z a $archive c:\gopath\bin\lxc.exe

Output: https://ci.appveyor.com/project/lxc/lxd/build/master.189#L112

    Hi Anatoly,

    This is mostly just looks this way, because appveyor first displays whole script it is planing to execute, but actually echo output is really displayed right after command executed. If you want more sequential look, do it not as a script block, but as a separate commands like this:

    # powershell capture command output into variable
    - ps: $version = lxc version
    - ps: echo $version
    # pack lxc as aftifact for upload
    - ps: $archive = "lxc-$version-windows-amd64.zip"
    - 7z a $archive c:\gopath\bin\lxc.exe

    Thank you,
