Perhaps you are running on a JRE rather than a JDK?如何解决?

在windows环境下用idea打包项目都是没问题,把项目移到ubuntu里使用mvn clean package docker:build构建镜像报错

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:compile (default-compile) on project microservice-discovery-eureka: Compilation failure

这是java -version的信息

java version "1.7.0_79"
Java(TM) SE Runtime Environment (build 1.7.0_79-b15)
Java HotSpot(TM) 64-Bit Server VM (build 24.79-b02, mixed mode)

这是mvn -version的信息

Apache Maven 3.3.9
Maven home: /usr/share/maven
Java version: 1.7.0_79, vendor: Oracle Corporation
Java home: /usr/lib/jdk1.7.0_79/jre
Default locale: zh_CN, platform encoding: UTF-8
OS name: "linux", version: "4.10.0-28-generic", arch: "amd64", family: "unix"

本人对linux不太熟悉,折腾了1天了,希望大神帮助下

Perhaps you are running on a JRE rather than a JDK 这句话的意思是你可能仅装好java程序的执行环境，而没有java的开发环境(jdk). 试下安装一个jdk再看了.
