Hi Martin,
I am also trying to get your template up and working on my machine. I
do not use git so I downloaded the zip files directly. I'm on a Windoze
machine.
I was able to successfully clean and install junit4runner, but then I
am hitting what to me is a very strange error when building the neo4j
resources. However, I am a complete Maven newbie, so it might simply
be something I'm not understanding, or it may be that I did not unzip
the source files into the correct directories.
I have a main directory (neo-scala-stuff : - ) and then i have
teigen-scalatest-junit4runner, ept-neo4j-resources, and
ept-neo4j-scala-template as directories under that. Is that a
reasonable structure?
The error I am getting is "java.lang.NoClassDefFoundError: and"
Do you have a class named "and" in this? I admit i have not looked
through all the classes and I certainly at this time don't understand
Scala that well, but this seems like an unusual class name. Is this
something with Maven?
Any thoughts or pointers would be appreciated, and I apologize in
advance if this is some boneheaded newbie thing I'm doing. I've been
programming in Java (and Groovy/Grails) for a while, but I'm tackling
two new technologies here with Scala and Maven.
Regards,
doug
