Invalid class name exception on db-migration files

[robertoschwald]

Environment:
code-coverage 2.0.3-3
Grails 2.4.4
Fork mode disabled in test

I use database-migration files of name

<date>_purpose.groovy

e.g. 
2015-01-01_justASample.groovy

This leads to coverage errors on all of those files (see below).
I'm unable to exclude those files in the config to get rid of the error. Tried with

coverage {
  exclusions = [
    '*201*', // migrations
    '**/20*',
    '**/20*/**'
  ]
}

We use the following exclusions does this work for you?

"changelog*", "2012-*", "load_*", "remove_*", "2013-*", "2014-*", "2015-*" // migrations

[robertoschwald]

No, it doesn't work. Even used your exclusion list in BuildConfig.groovy, but error is the same.
db-migration files and changelog.groovy are in the default grails-app/migrations dir.

Now I switched on Grails forked mode for test env (was set to false in grails.project.fork as you've written it is not supported in the coverage plugin for now), and it seems the exclusion works then, but after the unit test, I get:

This is how the test is performed:

grails test-app unit: -echoOut -coverage -nopost --non-interactive --plain-output --stacktrace --verbose

when disabling forked mode, "Invalid class name" error for all migration files reoccurs.
