but but I don't know what osgi and project bundle stuff really is :) I don't think I would need that for what I want. (if those mean building as .jar or using jars) What I actually want is to keep the neo4j-community project (which is git linked to the github sources), keep this as source only (without having it bundled or exported as jar, but probably having it compiled as classes aka build project) and have this project used by other projects(by simply including the project instead of its .jars or anything else), so that I can see the javadoc(and jump to the source) and even eventually edit a few parts (of neo4j) and add ie. a System.out.println() (if it were bundled I couldn't do that, unless I'd rebundle it, that would be a headache to do on each modify or git fetch). In other words, I want to be able to use neo4j, from the sources (no .jars). I've been able to use other projects like this before (ie. jmonkeyengine aka jme3). In this regard, is there a better fix? Thank you.
