I have made a JAR from SimpleGraph which I want to use it in a separat project.
In my own project I can see and use the direct classes of SimpleGraph like ExcelSystem etc. but can not use the underlying classes as Vertex etc. from Tinkerpop/Gremlin.
Is there a way to include these into the JAR generation?
The installation instructions at http://www.bitplan.com/index.php/SimpleGraph-Installation have been updated according to your question.
To include simplegraph as a single jar dependency for your project you might want to run:
cd com.bitplan.simplegraph/simplegraph-bundle mvn install -D skipTests -D gpg.skip -P createAssembly
which will create a jar-with-dependencies.jar
