我想在centos 7.1上安装zkui，但是我有这个错误。

MV版本：

[root@server-1 zkui]# mvn -v
Apache Maven 3.5.2 (138edd61fd100ec658bfa2d307c43b76940a5d7d; 2017-10-18T03:58:13-04:00)
Maven home: /usr/local/maven3
Java version: 1.8.0_151, vendor: Oracle Corporation

OS name: "linux", version: "3.10.0-229.el7.x86_64", arch: "amd64", family: "unix"

还有我的 JAVA_HOME ：

[root@server-1 zkui]# echo $JAVA_HOME  
/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.151-5.b12.el7_4.x86_64/jre
java maven

    与错误消息提示一样，您没有安装 Java 开发工具包 (JDK)，只安装了 Java 运行时环境。JDK 是 JRE 的超集，包括用于开发 Java 程序的工具、Maven 插件所需的 Javac Java 编译器等工具。要修复，请安装 JDK。
