Grape in Gremlin

[Viktoras Veitas]

Hello,

Is there any possibility to use Grape in Gremlin REPL in a way it can be done in a Groovy Shell?

groovy:000> groovy.grape.Grape.grab([group:'org.apache.commons',module:'commons-math3',version:'3.0'])
===> null
groovy:000> import org.apache.commons.math3.linear.RealVector
===> [import org.apache.commons.math3.linear.RealVector]
groovy:000>

After all, Gremlin is "basically a Groovy shell", or it used to be, but:

gremlin> groovy.grape.Grape.grab([group:'org.apache.commons',module:'commons-math3',version:'3.0'])

Hi,

I've used ?Ivy? in the past via Gremlin. I simply put the jars in the lib/ directory and tada!

HTH,

Marko.
