> Currently if I start ignite-web-agent with incorrect options it crashes with exception:
> {code}
> ./ignite-web-agent.sh dfsd
> [15:48:36,554][INFO ][main][AgentLauncher] Starting Apache Ignite Web Console Agent...
> Exception in thread "main" com.beust.jcommander.ParameterException: Was passed main parameter 'dfsd' but no main parameter was defined
> 	at com.beust.jcommander.JCommander.getMainParameter(JCommander.java:914)
> 	at com.beust.jcommander.JCommander.parseValues(JCommander.java:759)
> 	at com.beust.jcommander.JCommander.parse(JCommander.java:282)
> 	at com.beust.jcommander.JCommander.parse(JCommander.java:265)
> 	at com.beust.jcommander.JCommander.<init>(JCommander.java:210)
> 	at org.apache.ignite.agent.AgentLauncher.main(AgentLauncher.java:53)
> {code}
> Will be much better if we will be handle such case and show some user-friendly info, for example the same as with --help option.
