在使用maven的自动导包功能给junit导包时，出现warning：
'dependencies.dependency.version' for junit:junit:jar is either LATEST or RELEASE (both of them are being deprecated) @ line 20, column 22
It is highly re***mended to fix these problems because they threaten the stability of your build.
For this reason, future Maven versions might no longer support building such malformed projects
发现使用自动导包功能时，version标签自动给了值：RELEASE（如下图）
解决方法：
将鼠标放在junit上，此时会显示junit的版本（我这边是4.13.2），然后将RELEASE改为提示版本即可。
