OrientDB graph mode - orientdb

Question

I am new in OrientDB. I have several questions.
1) Where i can find list of current stable version of *.jar libraries to acess OrientDB instance (version 2.0.3).
I use java 8 .
I connect to Orient DB from Java Spring. In pom.xml I write such lines:
<dependency>
<groupId>com.orientechnologies</groupId>
<artifactId>orientdb-core</artifactId>
<version>2.0</version>
</dependency>
<dependency>
<groupId>com.orientechnologies</groupId>
<artifactId>orient-commons</artifactId>
<version>2.0-M1</version>
</dependency>
<dependency>
<groupId>com.orientechnologies</groupId>
<artifactId>orientdb-enterprise</artifactId>
<version>2.0.2</version>
</dependency>
<dependency>
<groupId>com.orientechnologies</groupId>
<artifactId>orientdb-client</artifactId>
<version>2.0.2</version>
</dependency>
And everything is working, unless I add library to work with instance as with graph db
<dependency>
<groupId>com.orientechnologies</groupId>
<artifactId>orientdb-graphdb</artifactId>
<version>2.0.4</version>
</dependency>
If I add "orientdb-graphdb" reference, my code works in wrong way, actually in one my controller where object of "org.codehaus.jackson.node.ObjectNode" is returned, this controller fails. it seems that some error occurs during converting of ObjectNode.
2) I can't sort out how to use both Document and Graph model of OrientDB in one instance. Which *.jar file to use and of which versions.
I think, the course of my troubles is wrong combination of jar files of wrong versions.

You have mixed the versions as you imagined. You should try having everything at 2.0.5 for example
I had the same issue.. I had to figure it out myself based on what was online in the repositories but it was tough with the latest snapshots when I was reading guidelines from outdated documentation.
Here for the stable ones: http://mvnrepository.com/artifact/com.orientechnologies
and here for the snapshot ones: https://oss.sonatype.org/content/repositories/snapshots/com/orientechnologies/
You need to put this one as a dependency:
<dependency>
<groupId>com.orientechnologies</groupId>
<artifactId>orientdb-graphdb</artifactId>
<version>2.0.5</version>
</dependency>
and this will fetch orientdb-core and all the others that it needs - so start from that and then add whatever is not in its dependencies that can be found here
In your case for example orientdb-graphdb 2.0.4 was trying to fetch orientdb-core 2.0.4 but you already had the dependency of orientdb-core 2.0.0 in there.
You can have repositories in your pom.xml like that (although I think there are better ways to configure them):
<repositories>
<repository>
<id>sonatype-nexus-snapshots</id>
<name>Sonatype Nexus Snapshots</name>
<url>https://oss.sonatype.org/content/repositories/snapshots</url>
</repository>
<repository>
<id>mvn-repository-com-artifacts</id>
<name>mvnrepository.com</name>
<url>http://mvnrepository.com/artifact/</url>
</repository>
</repositories>
