react-native：构建因异常而失败

Question

After upgrading from 0.17 to 0.19 I'm getting this error every time I'm trying to build the application using ( react-native run-android ). I've tried downgrading back to 0.17 but it didn't help and the problem is the same. I've also searched the web but couldn't find anything similar to my problem . I guess the problem is with gradle not the react-native itself but I don't know how to solve it ?!

Here is the error :

Starting JS server...
Starting the packager in a new window is not supported on Windows yet.
Please start it manually using 'react-native start'.
We believe the best Windows support will come from a community of people
using React Native on Windows on a daily basis.
Would you be up for sending a pull request?
Building and installing the app on the device (cd android && gradlew.bat install
Debug)...

Make sure you have an Android emulator running or a device connected and have
set up your Android development environment:

I appreciate any help :)

I had the same problem some days ago . It seems that you have a problem with connection , a slow one, or the site is blocked by your ISP (for any reason) or filtered by you country (like china). Try using a Proxy and try again, it worked for me .

By the way the problem is not with react-native, its with gradle. And the community will include these jar files with react-native package in v0.21 which is coming this week and your problem with jcenter will be solved I hope .
