在碰到maven install 发现报错
Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.2:compile (default-compile) on project autotest_fchtgl: Compilation failure

分析：
对这个问题其实报错中已经说的很清楚了，看第一条最后的 Perhaps you are running on a JRE rather than a JDK?
就是说你可能编译在一个JRE而不是JDK上，maven 编译是要JDK的，可能你的编译器配置了一个jre路径。
解决：
在eclipse中，选择window→preference→java→Installed JREs 点add添加你的jdk路径，选jdk而不是jre,之前的报错原因就出在这里。
然后右键你的maven工程，在maven中点击update project，然后maven clean,install 一下就好了。
