原因是Gradle下载超时
一.下载
https://gradle.org/releases/
二.安装
$ mkdir /opt/gradle
$ unzip -d /opt/gradle gradle-4.10.-bin.zip
$ ls /opt/gradle/gradle-4.10.
LICENSE NOTICE bin getting-started.html init.d lib media
三.配置系统变量
$ export PATH=$PATH:/opt/gradle/gradle-4.10./bin
四.验证
$ gradle -v ------------------------------------------------------------
Gradle 4.10.
------------------------------------------------------------
