Running code analyzer without any arguments throws a NullPointerException #30

Open rofrano opened 4 months ago

rofrano commented 4 months ago

When running code analyzer without any arguments it throws a java.lang.NullPointerException.

It would be nice if it printed out some helpful information about how to use it instead. ;-)

$ java -jar codeanalyzer.jar
