datanucleus-core-.jar 3.0.7 conflict with maven-datanucleus-plugin

project --topLevelPackage com.regressiontest --projectName temp2
persistence setup --provider DATANUCLEUS --database GOOGLE_APP_ENGINE
//Creating Company
entity jpa --class ~.domain.Company
field string --fieldName name --sizeMax 50
json add --class ~.domain.Company
web mvc setup
web mvc controller ~.controller.CompanyController
web mvc json add --jsonObject ~.domain.Company --class ~.controller.CompanyController

Causes conflict with maven-datanucleus-plugin which wants version 3.0.8 but 3.0.7 is project dependency. Changed project dependency to <scope>runtime</scope> as fix.
