The OrientDB development team is very active so if you’ve started learning OrientDB right now we suggest to clone the source repository and use the “develop” branch (latest SNAPSHOT). Follow these instructions. Is a snapshot stable enough? All the SNAPSHOTs pass the thousands of test cases, so the answer is YES. However don’t worry, we usually create a new stable release from the SNAPSHOT about every 3 months. If however you’re afraid of using a SNAPSHOT yet, it’s ok: use a stable one and follow the Installation instructions.

For older release or more information go to the official download page.

What distribution should I use ?

OrientDB comes with 2 distributions:

• OrientDB Community Edition, the default Open Source version released with Apache 2 license
• OrientDB Enterprise Edition, based on the Community Edition, adds Enterprise Level features. It’s available with support by Orient Technologies company and has a commercial version.

Version numbers

Starting from release 1.0 OrientDB uses the Semantic Versioning approach.

Consider a version format of X.Y.Z (Major.Minor.Patch). Bug fixes not affecting the API increment the patch version, backwards compatible API additions/changes increment the minor version, and backwards incompatible API changes increment the major version.

This system is called “Semantic Versioning.” Under this scheme, version numbers and the way they change convey meaning about the underlying code and what has been modified from one version to the next.

Download binaries from Maven repository

Get single binaries as jars form the Sonatype’s Official Maven Repository.

Latest Snapshot

This is the suggested download if want to have and use the last version with all the new features and bugs fixed. Snapshot builds always compile and pass all the test cases. These packages don’t contain the “GratefulDeadConcerts” database. To create it just run the test suite with “ant test”.

This is the place where you can always find the last version automatically compiled from Git at every change: http://helios.orientechnologies.com

Via MAVEN repository

If you want to use OrientDB through Java the best and easy way is through Apache Maven. If you want to use the client/server version you need the Full distribution.

Add this snippet in your pom.xml file:

Add “bundle” artifact type to the list of Maven types

Compile it by your own

The OrientDB development team is very active, so if your in the middle of the development of your application we suggest to use last SNAPSHOT from the git source repository. All you need is:

• JDK (Java Development Kit) 6+
• git SCM tool
• Apache Ant v1.8.2+

Then follow these simple steps:

> git clone --branch develop https://github.com/orientechnologies/orientdb.git
> cd orientdb
> ant clean install

At the end of the build you will have a brand new distribution under the path: ../releases/orientdb-community-2.0-SNAPSHOT. Use it as a normal OrientDB distribution directory.

Every time you want to update your distribution with last changes do:

> git pull origin develop
> ant clean install

At the end of the build your distribution (../releases/orientdb-community-2.0-SNAPSHOT) will be updated with last OrientDB libraries.

Every time you compile a new version, assure to have the permissions to execute the .sh files under the “bin” directory:

> cd ../releases/orientdb-community-2.0-SNAPSHOT/bin
> chmod u+x *.sh
