Avoid cyclic reference inheritance in grails

Question

I have a big project written in Grails 2.3.8. Sometimes when I deploy it using my CI I got this message:

Unable to complete the scan for annotations for web

Answer 1

I think its because of two versions of JAR being referenced from classpath.

This is usually caused when different versions of bcprov-jdk*.jar being loaded.

For example, IN one of my scenario - I had 

..../webapps/FOO/WEB-INF/lib/bcprov-jdk15on-147.jar
..../webapps/FOO/WEB-INF/lib/bcprov-jdk15on-1.51.jar 

I got this resolved after removing any one of them from my classpath.
