Problem description:

Project was developed by using jdk1.6, running in the jetty plugin, run on eclipse without problems, the same code to run on the idea of an error:

Error prompt is very simple, do not support 1.7 class files, but project run Settings is jdk1.6.
Project can only use 1.6 to compile,

Idea related configuration is as follows:




Have tried to fix: project is a maven project, maven - clean, the idea itself invalidate cache, is still an error,

The most magical is: others idea version, code, run is not an error,

Has many days, please met the same problems or have ideas, help to look at, thank you!
