Gradlew does not build if root

I am trying to create a gradle android project on a centos 7 server. When I run ./gradlew assembleDebug

it says

FAILURE: Build failed with exception.

• What went wrong: Could not determine a usable local IP address for this machine.

And I logged an error with --stacktrace

which shows the following log:

Picked up _JAVA_OPTIONS: -Djava.net.preferIPv4Stack=true

FAILURE: Build failed with an exception.

* What went wrong:
Could not determine a usable local IP for this machine.

* Try:
Run with --info or --debug option to get more log output.

* Exception is:
java.lang.RuntimeException: Could not determine a usable local IP for this machine.

But, when I run root user, build succeeds and I have apk. The weird problem is that it still fails even if I run gradlew as sudo

. It only runs as root (#).

Does anyone know of any solution?
