| = Gremlin Server Application |
| |
| This is a starter project that demonstrates how a basic |
| link:http://tinkerpop.apache.org/docs/${project.version}/reference/#gremlin-server[Gremlin Server] project is structured |
| with Maven. This project demonstrates how to connect to Gremlin Server with Java using remote traversals with the |
| link:http://tinkerpop.apache.org/docs/${project.version}/reference/#connecting-via-remotegraph[Gremlin Driver] that is |
| distributed by TinkerPop. |
| |
| == Prerequisites |
| |
| * Java 11 |
| * link:https://maven.apache.org/[Maven 3.3+] |
| * Gremlin Server is link:http://archive.apache.org/dist/tinkerpop/[downloaded] and unpackaged |
| |
| == Building and Running |
| |
| Build the project as follows: |
| |
| [source,text] |
| mvn clean package |
| |
| Start Gremlin Server in the directory it was unpackaged and specify usage of the "modern" graph configuration: |
| |
| [source,text] |
| $ bin/gremlin-server.sh conf/gremlin-server-modern.yaml |
