I checked out https://svn.codehaus.org/jbehave/trunk/core/examples/trader referenced on http://jbehave.org/reference/latest/reports.html and running mvn test did not succeed as:

• there is no jbehave-examples-2.5-SNAPSHOT parent pom available from the standard maven repositories.

• there is no mentioning which mvn command I should invoke to create the report.

Checking out the whole core trunk at https://svn.codehaus.org/jbehave/trunk/core/, running mvn install, changing to expamples/trader afterwards and running mvn clean integration-test site would produce the expected output at target/jbehave-reports/rendered/index.html.
