Ionic build freezes

hi,after I execute this command

ionic build android --release --device --verbose freezes

I got this tailing output:

BUILD SUCCESSFUL

Total time: 8.116 secs
Built the following apk(s):

No scripts found for hook “after_compile”.
No scripts found for hook “after_build”.

and it freezes there, sometimes took longer than 10 minutes, sometimes no more than 10 seconds. I’m using Teamcity CI, this stall time really pains a lot.

Can someone shed some lights on what’s ionic doing by then(accessing s3 to fetch update status, maybe)?

try reboot???

Tried, but still…

only: ‘ionic build android’ works?

works, but freezes at last looks like it’s reading web
