Hibernate validation "Unable to initialize javax.el.ExpressionFactory" error

None of the above worked for me However This did: Right click on the project > Properties > Project Facets on the right most area select Runtimes tab and selct your Tomcat Runtime, this will provide the required libs available to the test. enter image description here

You have 2 different incompatible versions of javax.el (3 and 2).

Just use this dependency, which will cover everything (it's the one we recommend in the GitHub repo's README.md but I need to update the getting started guide):


and remove all the other javax.el dependencies (API and impl). It should work like a charm once you're done.
