Grails plugin - this expression must be true

Salve galera,


Outro dia me deparei com o erro abaixo no grails 2.3.4. Para resolver basta atualizar o plugin abaixo da seguinte forma:

compile ':plugin-config:0.2.0'

Caused by IllegalArgumentException: [Assertion failed] - this expression must be true
