  解决方法： 进入sdkman的安装包目录，手动下载gradle对应的zip包版本，重命名为 gradle-version.zip   然后在【sdk install gradle 2.14.1】进行安装   1、手动下载gradle的地址 https://services.gradle.org/distributions/  

wget https://downloads.gradle-dn.com/distributions/gradle-2.14.1-all.zip

  2、copy zip包到sdkman的压缩包目录下 压缩包路径：/root/.sdkman/archives   文件名字要改为：gradle-2.14.1.zip   3、重新执行命令安装对应版本gradle

sdk install gradle 2.14.1
