问题：
maven运行时遇到
Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.2:compile (default-compile) on project autotest_fchtgl: Compilation failure
[ERROR] No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK?

分析：
maven要编译在一个jdk上，而不是jre，可能编译器配置了一个jre路径。

解决：
Preferences→Java→Installed JREs 点击add…添加jdk安装路径

右键项目→Maven→Update Project 。然后重新运行Run As→Maven Install。大概可以解决。
