Grails 2 and mongodb not working - mongodb

Question

I am using Grails 2.2.0 and MongoDB. I have configured Grails to run against MongoDB instead of the default H2 in memory database. From the error message h2 seems to be involved even though I think I removed it.
My DataSource.groovy:
grails {
mongo {
host = "localhost"
port = 27017
databaseName = "physicians"
}
}
My BuildConfig.groovy:
plugins {
runtime ":hibernate:$grailsVersion"
runtime ":jquery:1.8.0"
runtime ":resources:1.1.6"
// Uncomment these (or add new ones) to enable additional resources capabilities
//runtime ":zipped-resources:1.0"
//runtime ":cached-resources:1.0"
//runtime ":yui-minify-resources:0.1.4"
build ":tomcat:$grailsVersion"
runtime ":database-migration:1.1"
compile ':cache:1.0.0'
compile ':mongodb:1.1.0.GA'
}
The error I get when i want to save a domain object Artist is:
| Error 2013-01-03 22:33:18,881 [http-bio-9090-exec-1] ERROR util.JDBCExceptionReporter - Table "ARTIST" not found; SQL statement:

What am I missing here?

====================================
Got it working.
First I had to remove the line
runtime ":hibernate:$grailsVersion"
from the BuildConfig.groovy
When I did that I got this:
| Error Fatal error during compilation org.apache.tools.ant.BuildException:
java.lang.NoClassDefFoundError: org/hibernate/cfg/Configuration
(NOTE: Stack trace has been filtered. Use --verbose to see entire trace.)
I then removed the line
runtime ":database-migration:1.1"
from BuildConfig.groovy
This last part was not found when searching to solve this problem. Is this the way it is supposed to be done?

Answer 1

To use mongodb gorm stand alone in your project, you need to comment out
compile ':cache:1.0.0'
in your BuildConfig, because cache plugin depends on hibernate. You can find it in the source code as:
plugins {
....
runtime(":hibernate:$grailsVersion") {
export = false
}
....
}

Answer 2

I had to remove Hibernate plugin from application.properties too for it to work. I am not sure why hibernate plugin was configured in application.properties

Answer 3

You had uninstalled the hibernate, so you need another plugin about mongodb.
you cound add a line
compile ':mongodb:1.0.0.GA'
from BuildConfig.groovy instead of
runtime ":hibernate:$grailsVersion"
