This is a Neo4j Server plugin, providing Gremlin backend scripting to the Neo4j Server. To deploy, please do the following
For usage, see the current documentation.
Ensure Maven knows where to find Java 1.7. Note: on Mac OSX (tested on 10.9), please see this issue/workaround StackOverflow.
Also ensure you do not have neo4j currently running or the build tests will fail as it attempts to start up a neo4j instance on the same port as the defaults for neo4j. Otherwise the tests and the build will fail.
mvn clean package
unzip target/neo4j-gremlin-plugin-2.1-SNAPSHOT-server-plugin.zip -d $NEO4J_HOME/plugins/gremlin-plugin
cd $NEO4J_HOME
