我尝试在centos 7服务器中构建一个gradle android项目。我跑的时候
./gradlew assembleDebug它说
失败：构建因异常而失败。
- 出了什么问题： 无法确定此计算机的可用本地IP。
我用--stacktrace记录了错误，显示以下日志：
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.

但是，当我以root用户身份运行时，构建成功并且我有apk。奇怪的问题是，即使我将gradlew作为sudo运行，它仍然会失败。只以root（＃）执行它。
任何人都知道任何解决方案吗？
