Huh? Gremlin 0.8-SNAPSHOT uses Groovy 1.7.8 (which was released maybe 1 week
ago). Gremlin 0.7 was using Groovy 1.7.5. Perhaps something about that was
making it burp? What do you mean "add it by hand?"

Were you compiling a Pipe or a Gremlin statement? Compile can only be used to
create a Pipe:
public static Pipe compile(final String gremlin);
See the first section of:
https://github.com/tinkerpop/gremlin/wiki/Using-Gremlin-through-Java
If you want to do an arbitrary Gremlin statement, then you use
GremlinScriptEngine.eval();
?? Or, is it because you haven't linked Groovy into your project. Realize that
Gremlin class is Gremlin.groovy, not Gremlin.java. Thus, you need to make sure
you have gmaven-pluggin support in your pom.xml. See the second section of:
https://github.com/tinkerpop/gremlin/wiki/Using-Gremlin-through-Groovy

Gotcha.

Cool. You can get around that by using Gremlin.compile() :P. In that way, you
can compile a Gremlin statement to get the raw Pipes.
Enjoy,
