Can not find exe file

When I use proxy to download sevenzip component, Android Studio prompt the following errro:

Could not find SevenZip-osx-x86_64.exe (
Searched in the following locations:

But, actually, I can download the exe file using the url.
Why Android Studio can not find the file.

If you can download the file directly then I don’t see how this is a Nexus problem. I’d suggest examining the log files from the build closely to see what is causing this. Also try downloading that URL directly from the build machine, it could be that it is blocked there.
