how import CSV into neo4j

Question

I am very new in Neo4j. I downloaded neo4j 1.9 for windows. And I tried to run the code in Gremlins in order to import CSV files into Neo4j. I saved CSV files (One of them includes nodes and another one contains relationships) into a new folder, named target, in graph.db. Then I executed this line:

java -server -Xmx4G -jar ../batch-import/target/batch-import-jar-with-dependencies.jar neo4j/data/graph.db nodes.csv rels.csv

But I got this error:

startup failed

==> groovysh_parse: 51: expecting EOF, found 'target' @ line 51, column 42.
==>    r -Xmx4G -jar ../batch-import/target/bat
==>                                  ^
==>

I got the same error when I ran this:

"git clone git://github.com/jexp/batch-import.git"

When i wanted to install maven via this code:

 "sudo apt-get install maven2"

I got this error:

No such property: apt for class: groovysh evaluate.

I will be appreciated, if help me to import csv Files into Neo4j. Thanks Fatemeh

on windows, maybe you could try import the batch via gremlin's command importGraphML - docs.neo4j.org/chunked/snapshot/… . just try to create the proper graphml xml file instead of your csvs. — ulkas

The documentation https://github.com/jexp/batch-import focusses on Mac and Linux system. When running on Windoze, you need to convert all unix path seperators ("/") into the windows equivalent ("\").

Also the apt-get command is Linux specific.
