More grails-shell-cli errors

Issue description

When running ./gradle assemble after a ./gradle clean, the classpath for grails-gradle-model will be incorrect (/dist vs /lib) because it does not yet exist in /lib within the project when the task is run. Running ./gradle assemble again produces working classpaths in grails and grails.bat
