Possible issue with ehcache plugin on grails 3 - grails

Question

configured was :
compile 'org.grails.plugins:cache-ehcache:2.0.0.BUILD-SNAPSHOT'
This problem did not seem aparent whilst testing the app using grails run-app or grails prod run-app.
when I made a war and ported it over to tomcat, upon starting the app I had this error and the app would not start up. I removed a load of references to any thing related to cache and still had same issue. I found after disabling above plugin it started up.
This is the stack trace (Maybe it relates to multiple dsn) I did try to follow the issue link but the jira link was down:

Answer 1

I had the same problem and managed to get round by doing following changes in the build.gradle:
compile ("org.grails.plugins:cache-ehcache:3.0.0.BUILD-SNAPSHOT") {
exclude group:'net.sf.ehcache'
}
compile "net.sf.ehcache:ehcache:2.4.3"
It appears that the cache-ehcache:3.0.0.BUILD-SNAPSHOT uses newer ehcache(2.10.2) than the one coming with grails for hibernate caching (2.4.3 core). When both are included in the war the ehcache startup fails in tomcat.
Tested with grails 3.0.17.
