最近使用eclipse时在maven中安装Tomcat插件出现错误
话不多说，先来一段错误提示
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:compile (default-compile) on project SingleWebTest: Compilation failure [ERROR] No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK? [ERROR] -> [Help 1] [ERROR] [ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch. [ERROR] Re-run Maven using the -X switch to enable full debug logging. [ERROR] [ERROR] For more information about the errors and possible solutions, please read the following articles: [ERROR] [Help 1] http://cwiki.apache.org/confluence/display/MAVEN/MojoFailureException
这段话的大致意思是：环境中不提供编译器，也许你运行的是JRE而不是JDK？
于是我打开eclipse一看，我的JDK呢？？？？如下图
查了一下资料，原来eclipse是默认运行在JRE上的，如上图是JRE1.8.0，而不是JDK1.8.但是maven又需要JDK，这可咋整？

咳咳咳，划重点了，解决办法如下
打开【Window】-->【Prefrences】-->【Java】-->【Installed JREs】如下图
点击【add】-->【Standar VM】-->【next】
找到JDK路径，然后【finish】
关闭窗口，勾选上刚才安装的JDK
点击OK，然后重新【maven build】一下

成功构建，收功。
解决Perhaps you are running on a JRE rather than a JDK?和MojoFailureException问题
