linux安装gradle，简单迅速亲测有效

sudo yum install java-1.8.0-openjdk-devel

jdk咱就不说了，正常服务器安装gradle下载就需要很久，这个很快

wget https://services.gradle.org/distributions/gradle-5.0-bin.zip -P /tmp

 unzip gradle-5.0-bin.zip，解压

 然后配置环境变量

export GRADLE_HOME=/opt/gradle/gradle-5.0
export PATH=${GRADLE_HOME}/bin:${PATH}
