centos下maven编译 mvn package 报错：

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:compile (default-compile) on project helloworld: Compilation failure
[ERROR] No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK?

Apparently,it requires tools.jar file inside the lib folder of my $JAVA_HOME. I did not have the lib folder,so I reinstalled my jdk using command

apt-get install openjdk-7-jdk openjdk-7-doc openjdk-7-jre-lib
Also,this link may help some people.

注意，假如你是jdk8的请将7替换成8。

centos 用这个
yum -y  install openjdk-8-jdk openjdk-8-doc openjdk-8-jre-lib

解决方案

在centos7的terminal中输入java -verison是没问题的，但是javac的话就会提示没有此命令
百度了好久，说的很复杂，照着做了，最后也没有成功
后来在stackoverflow上看到了这个

You installed the Java Runtime Environment (JRE) only,which does not contain javac. For javac,you have to install the OpenJDK Development Environment. You can install java-devel or java-1.6.0-openjdk-devel,which both include javac.
By the way: you can find out which package provides javac with a yum search,e.g.
su -c ‘yum provides javac’
Another note: using yum and openjdk is only one possibility to install the JDK. Many people prefer Sun/Oracle’s “original” SDK. See How to install Java SDK on CentOS? and links for alternatives.

大意就是我们用yum来装原生的就行了 使用 yum install java-devel 就行了
