Kibana Windows build is stuck on "Running bin/kibana to trigger the optimizer"

[azasypkin]

Just tried to build Kibana on Windows 10 and the build never ends, it's stuck on "Running bin/kibana to trigger the optimizer" (30+ mins). Tried on VM and real hardware.

Here is stdout and ls .\build\kibana\optimize\bundles\

So far I have not been able to reproduce this, though we are other similar reports with plugin installation.

Interesting, wondering if "shell" matters, I've got the same results for built-in cmd shell and PowerShell.

I'm seeing the same problem with Windows Server 2016

Seeing the problem on Windows Server 2016 VM also. I waited over an hour, before I issued a control-c.

It appears this issue is due to the process not ending when calling kill https://github.com/elastic/kibana/blob/master/src/utils/watch_stdio_for_line.js#L55

I met the same problem in windows 10.

I am facing the same issue on Windows Server 2016 when installing the Search Guard plugin. Interestingly, when installing the plugin on Windows 10, everything is all right, but the issue occurs on Windows Server 2016.
Elastic version: 6.5.4

Any solutions?
