Can't start after installation

I installed Bitsy on Tinkerpop 3.3.3 and Java 8.161 on OSX.

I followed the installation instruction for the gremlin-server. I changed the port to 9182 and the path for the data to an empty directory.

I get the following feedback : Apparently, the main class com.lambdazen.bitsy.BitsyGraph is not found, yet all the jar are available.

This seems like a simple error, but I don’t know where to start.

I use ext/bitsy/plugin (and ext/bitsy/lib as for that matter, but as i see from console.sh only the former is searched by it. It works for OK.

Thanks @cstamas and @dseguy ! I see that the Gremlin .sh files refers to ‘plugin’ in a sed script – https://github.com/apache/tinkerpop/blob/a418226574f85d3289807f8bae5d28adc2114895/gremlin-console/src/main/bin/gremlin.sh – which isn’t there in the .bat files.

I have updated the docs. This should work on both Win & Unix. Thanks again!
