jdk1.8换成11,启动项目报错java.net.MalformedURLException: unknown protocol: jrt

jdk11

Information:Internal caches are corrupted or have outdated format, forcing project rebuild: Module ‘messystem’ production: java.net.MalformedURLException: unknown protocol: jrt

解决：据说jdk11完美兼容以前jdk，但是项目是使用1.8 编写，报错，
在project structure->modules->
