I have found an article<http://blog.vogella.com/2013/01/03/tycho-advanced/> [1<http://blog.vogella.com/2013/01/03/tycho-advanced/>] by Dirk Fauth where he says the following (talking about using <pomDependencies>):

Thanks it worked for me as well.  I used the following directory and
this worked for me on linux:
${env_var:HOME}/.m2/repository/org/neo4j/driver/neo4j-java-driver/1.7.5

With this directory eclipse was able to pickup both neo4j-java-driver
and its source jar.

(of course, it requires having the HOME environment variable on windows,
but I have that anyway, since so many unixish/linuxy tools relies on
having the HOME variable set)

Hm... by "the neo4j JAR", do you mean the actual neo4J database?
(because that one is not an OSGi bundle and would require wrapping).

I decided not to try to include neo4j proper into eclipse, but instead
try to use the neo4j-java-driver (which _is_ a bundle) and run the neo4j
server as a separate process.

(Back in 2015 when I previously was tinkering with this project, I
rebundled neo4j before adding it to the target platform.  But I wasn¨'t
really successful)

Thanks again! You have been very helpful! :-)
