“Error loading plugin manager: TomcatGrailsPlugin” on Grails 2.3 Database Migration

Question

I use Grails 2.3 and the Grails database migration plugin (1.3.6).

When I do grails dbm-update I get the following error. How can I solve this error?

Answer 1

I'm on Grails 2.3.4, but here's how I fixed this problem:

1. Upgraded to database migration 1.3.8
2. Cleared my scriptCache folder
3. Executed refresh-dependencies

Retried the database migration script, and the problem was resolved.
