無法在.ZKUI 中找到 Javac 編譯器
我想在centos 7.1上安裝zkui,但是我有這個錯誤。

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 Java home: /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.151-5.b12.el7_4.x86_64/jre Default locale: en_US, platform encoding: UTF-8 OS name: "linux", version: "3.10.0-229.el7.x86_64", arch: "amd64", family: "unix"
還有我的 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
與錯誤消息提示一樣,您沒有安裝 Java 開發工具包 (JDK),只安裝了 Java 執行時環境。JDK 是 JRE 的超集,包括用於開發 Java 程序的工具、Maven 外掛所需的 Javac Java 編譯器等工具。要修復,請安裝 JDK。
我安裝
tools.jar
並解決。
[root@server-1]# yum install java-1.8.0-openjdk-devel
