I only upgraded plugins version in BuildConfig.groovy:
- build ':tomcat:7.0.55.2'
- compile ':cache:1.1.8'
- compile ':scaffolding:2.1.2'
- compile ':asset-pipeline:2.1.5'
I also met an exception because I forget to change cache.region.factory_class in Datasource.groovy ( cf Release Version ).
Here is the exception :
2015-03-31 16:28:39,590 [localhost-startStop-1] ERROR context.GrailsContextLoaderListener - Error initializing the application: Error creating bean with name 'transactionManagerPostProcessor': Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'transactionManager': Cannot resolve reference to bean 'transactionManager_lookup' while setting constructor argument with key [1]; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'transactionManager_lookup': Cannot resolve reference to bean 'sessionFactory_lookup' while setting bean property 'sessionFactory'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory_lookup': Invocation of init method failed; nested exception is org.hibernate.cache.CacheException: net.sf.ehcache.CacheException: Another unnamed CacheManager already exists in the same VM. Please provide unique names for each CacheManager in the config or do one of following:
1. Use one of the CacheManager.create() static factory methods to reuse same CacheManager with same name or create one if necessary
2. Shutdown the earlier cacheManager before creating new one with same name.
The source of the existing CacheManager is: DefaultConfigurationSource [ ehcache.xml or ehcache-failsafe.xml ]
...
To solves it, I only have to do the following change in Datasource.groovy :
hibernate {
...
cache.region.factory_class = 'org.hibernate.cache.SingletonEhCacheRegionFactory'
}
