1.安装gradle
1.gradle各版本下载跟路径/distributions/2.我们这里下载和kafka 2.3.1版本匹配的gradle版本，5.4.1/distributions/gradle-5.4.1-bin.zip3.解压cd /users/yyj/softtar xvzf gradle-5.4.1-bin.zip4.配置gradle环境变量,vi /etc/bashrc,添加如下配置：GRADLE_HOME=/users/yyj/soft/gradle-5.4.1 export PATH="$GRADLE_HOME/bin:$PATH" 5.验证并查看gradle版本gradle -version
输出以下信息表示成功：Gradle 5.4.1Build time: -04-26 08:14:42 UTCRevision:261d171646b36a6a28d5a19a69676cd098a4c19dKotlin: 1.3.21Groovy: 2.5.4Ant:Apache Ant(TM) version 1.9.13 compiled on July 10 JVM:1.8.0_131 (Oracle Corporation 25.131-b11)OS: Mac OS X 10.12.6 x86_64
