maven项目报错:找不到编译器

在运行maven项目时,报错

大概的意思是说，在当前环境没提供编译器。于是打开 window->preferences->java->install JREs，发现jre是正常配置的。



但是错误报的是找不到编译器，也就是JDK，后面还提醒了一句，也许你是在jre里面运行，而不是jdk。对照上图可以看到，确实是选择的只是jre。我们在安装java的时候，会在java目录下生成jre文件夹，同时在jdk文件夹下也生产jre文件夹。



所以，解决办法就是选择jdk目录下的jre，而不是java目录下的jre。点击edit->directory->选择jdk目录下的jre，就像这样



点击finish，然后在项目上右键->maven->update project，再运行，成功。问题解决
