Java.lang.LinkageError: loader constraint violation - Codes Helper

I want to use hibernate validation to implement back-end data validation. As required, I need to introduce EL dependencies. But when I added the javax.el dependency to .run, the following bugs, appeared and I looked up a lot of answers online. But still can not solve this mistake. I have removed the javax.servlet dependency. Also get rid of some javax-related jar. There will still be this mistake.

I put Tomcat plugin into maven.

follow is my error message
