新建maven项目的时候报错Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:compile (default-compile) on project testweb1: Compilation failure
使用-e参数，打印出错原因。如：mvn install -e
报错如下：
Maven install失败
Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1: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?

解决方案：
解决方案如下：
1、确认 eclipse windows--preferences--java--installed JREs 指定的是JDK安装路径，如果原来为JRE，需修改为JDK
2、确认 eclipse windows--perferences--java--installed JREs--execution environments
3、项目 右键 --properties -- java build path -- libraries -- jre system library [javaSE-1.8] 双击 -- execution environment: 选项如下图所示
