Random rebuild of entire module when starting tests

Doing same change (adding few empty lines) and running unit test sometimes forces rebuild of grails plugin and sometimes not.

**Logs when Intellij decided to rebuilt plugin:**

I have a project with inplace plugin. Plugin contains domain classess. Main project contains a test using that domain classess.
When I change a domain class in whatever way (even adding few empty lines) and run test from IDE, sometimes tests are passing and sometimes not.
Reason why they are not passing is groovy.lang.MissingPropertyException on a fields that is declared using gorm statics, like: static belongsTo = [author: Author]. Tests are passing when entire plugin is rebuilt. Failing when it is not rebuilt.

Start by reproducing the issue from the IntelliJ incremental build logs: edit a Grails in-place plugin domain class and run the main project's test from the IDE. Compare the Groovy compiler builder output when the plugin is rebuilt versus when it is not; done means domain classes with GORM statics load consistently and the tests pass after either edit.
