It checks nodes and parses through the graph to basically test for the 
presence of ways and flags. That's rather hard to analyze.

Its a black box to me. IntelliJ's maven plugin has recognized the 
configuration and i can run lifecycle jobs to build stuff and run the tests.

I built a runtime configuration in the IDE with parameters taken from 
graphhopper.sh so I can run graphhopper with the debugger in the IDE.

But I have no idea what maven does to run the tests or how to intercept 
that and run it directly in the debugger.

If found something that looks like it a jetty:run build target in the 
web project, but if I try and run that, I get [WARNING] The POM for 
com.graphhopper:graphhopper:jar:0.1-20130525.080839-10 is missing, no 
dependency information available

Works.

I switched to an unprepared graph and it's working now. Thanks.

That was the first thing I tried, even before he mentioned it. Just 
gives some error messages:
./graphhopper.sh: Zeile 2: $'\r': Kommando nicht gefunden.
./graphhopper.sh: Zeile 50: Syntaxfehler beim unerwarteten Wort `$'{\r''

Of course, I would love that. Import and mini UI work just fine - thats 
just starting a Java application from a classpath.
But I have no idea how to get at the stuff thats wrapped in command line 
maven.
