Version: 4.0.0.Beta2 - 14 January 2013
Hibernate OGM is an attempt to store data in a NoSQL data grid using the Hibernate ORM engine rather than rewriting a JPA engine from scratch.
The benefits are fairly obvious:
- reimplementing the complex JPA specification is a lot of work
- a new implementation would mature at a rather slow rate and risk of bugs would be high
- Hibernate is familiar to many people

To build the project, run
mvn clean install -s settings-example.xml
To build the documentation, set the buildDocs property to true.
mvn clean install -DbuildDocs=true -s settings-example.xml
If you just want to build the documentation, run it from the hibernate-ogm-documentation/manual subdirectory.
For rapid documentation testing, you can limit the generated format to html to speed up the process
mvn clean install -DbuildDocs=true -s settings-example.xml -Djdocbook.format=html_single
For executing the tests in the hibernate-ogm-mongodb and hibernate-ogm-integrationtest-mongodb modules, the embedmongo-maven-plugin is used which downloads the MongoDB distribution, extracts it, starts a mongod process and shuts it down after test execution.
If required, you can configure the port to which the MongoDB instance binds to (by default 27018) and the target directory for the extracted binary (defaults to ${project.build.directory}/embeddedMongoDb/extracted) like this:
mvn clean install -s settings-example.xml -DembeddedMongoDbTempDir=<my-temp-dir> -DembeddedMongoDbPort=<my-port>
To work with a separately installed MongoDB instance instead, specify the 'useExternalMongoDb' property:
mvn clean install -s settings-example.xml -DuseExternalMongoDb
This assumes MongoDB to be installed on localhost, using the default port. If you have MongoDB
installed on another host or use a different port, you can set the environment variables
MONGODB_HOSTNAME MONGODB_PORT and then run the test suite:
export MONGODB_HOSTNAME=mongodb-machine
export MONGODB_PORT=1234
mvn clean install -s settings-example.xml
