Compiling MQL files produces no output

Question

I'm trying to implement a GitHub action that compiles .mq4 files. Currently, I've got a Powershell script that does that, according to the format described here:

$url = "http://www.rosasurfer.com/.mt4/{0}/metaeditor.exe" -f $Version
$exePath = "metaeditor.exe"
if ($verbose) {
    Write-Host "Attempting download from $($url)..."
}

try {
    Invoke-WebRequest -Uri $url -OutFile $exePath
} catch {
    Write-Error "Failed to download MetaEditor from $($url), error: $($_.Exception.Message)"
}

Out-File -FilePath $LogFile

$args = New-Object System.Collections.Generic.List[string]
$args.Add("/portable")
$args.Add('/compile:"{0}"' -f (Resolve-Path $Files))
$args.Add('/inc:"{0}"' -f (Resolve-Path $Includes))
$args.Add('/log:"{0}"' -f (Resolve-Path $LogFile))
if ([System.Convert]::ToBoolean($SyntaxOnly)) {
    $args.Add("/s")
}

$exePath = Resolve-Path $exePath
try {
    Start-Process $exePath -ArgumentList $args
} catch {
    Write-Error "Compilation failed, error: $($_.Excaption.Message)"
}

gc $LogFile

The issue I'm having is that this script doesn't fail, but doesn't produce an .ex4 files either. The log file is also empty. I tried using fully-qualified paths to the instance of metaeditor, the input files, include directory and log file as was suggested here, but I'm still not getting anything.

So, it turns out this was an artifact of the version of MetaEditor I was using. I'm not sure why, but version 4.1370.0 wasn't producing any output. Changing the version to the most recent one, fixed the issue and I can now compile my .mq4 and .mqh files.
