idea每次修改java都要重启_每次重新加载pom时，停止IntelliJ IDEA切换java语言级别（或更改默认项目语言级别）...

Using IntelliJ 12, I have a java project and I use maven with a pom.xml.

My project is using java8, but it seems the default project language level has been set to 6 while importing the project.

I can change the language level to 8.0 (F4 -> Modules -> Language level) however every time I edit my pom.xml the project level is switched back to "use project language level", and I have to edit this settings again and again.

Is there something I need to add to the pom.xml to set the default language level to 8.0?

As per Mark's comment, here is how to do it:

org.apache.maven.plugins

maven-compiler-plugin

3.5.1

1.8
