从第一天接触maven至今，这个问题总像个苍蝇一样甩不掉，在用run命令启动项目的时候，时不时会报这个错：

 Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.0:compile (default-compile) on project fsly_service: Compilation failure

 http://cwiki.apache.org/confluence/display/MAVEN/MojoFailureException

全文如下：

这个问题有时有，有时没有，今天在一个外国网站上看到这个Exception的介绍：

https://cwiki.apache.org/confluence/display/MAVEN/MojoFailureException



从以上介绍看，好像是某个插件导致的问题。

下面的评论中有一条：



说的是内存不足会导致这个问题，这时，看看自己的电脑，开了好多程序，卡爆了。。。

于是关掉了一些，然后重新用  run 命令启动项目，OK，问题解决。。。
