problem:

My project name is system-web, mvn: the jetty by the start command path http: / can not access the home page 8080 / system-web: // localhost.

My solution:

pom inside the plugin no configuration path, with a run mvn pom that directory in the file system-web: jetty, jetty found path is available starting src / main / webapp. So access path is http: // localhost: 8080 / this on it. If you resolve your problem, please let me know praise.
