Grails 4.0.1 error enabling hibernate second level cache

I am having trouble enabling second level cache for hibernate using grails 4.0.1 version.

I have the following enabled in application.yaml

hibernate:
    cache:
        queries: false
        use_second_level_cache: true
        use_query_cache: false
        provider_class: net.sf.ehcache.hibernate.EhCacheProvider
        region:
           factory_class: org.hibernate.cache.ehcache.internal.EhCacheRegionFactory

I have the following in build.gradle

compile group: 'net.sf.ehcache', name: 'ehcache-core', version: '2.6.11'
compile "org.hibernate:hibernate-ehcache:5.4.0.Final"

Getting below error :

Anything I am missing from configuring second level cache for hibernate in this grails version 4.0.1 ?

Thanks.

Apparently, i had ehcache-core in my gradle build instead of ehcache.

This fixed my issue :

compile group: 'net.sf.ehcache', name: 'ehcache', version: '2.10.6'

Grails 4.0.1 uses hibernate 5.4.0, so left hibernate-ehcache version to 5.4.0 same as hibernate version.

Changed back cache configuration as below :

hibernate:
    cache:
        queries: false
        use_second_level_cache: true
        use_query_cache: false
        provider_class: net.sf.ehcache.hibernate.EhCacheProvider
        region:
           factory_class: org.hibernate.cache.ehcache.EhCacheRegionFactory

I have the same error, surprisingly today with grails 3.3.11 and removing

compile group: 'net.sf.ehcache', name: 'ehcache-core', version: '2.6.11'

and adding

compile "org.hibernate:hibernate-ehcache:5.1.17.Final"

helped me get past the error. My application.yml configuration is as follows


hibernate:
    cache:
        queries: false
        use_second_level_cache: true
        provider_class: net.sf.ehcache.hibernate.EhCacheProvider
        region:
            factory_class: org.hibernate.cache.ehcache.EhCacheRegionFactory
        use_query_cache: false
