@scofier Ever found a solution for this? Is it your resource or a conflict in pom dependencies?

It took me 6hrs to find the mistake there is a setting in the default example as
<securityDefinition>
<json>/securityDefinition.json</json>
</securityDefinition>

It was silly not to check the logs com.github.kongchen.swagger.docgen.mavenplugin.SecurityDefinition.getDefinitions(SecurityDefinition.java:31)

Just comment off that part.
As a fix to code there should be a file not exist check before the call

Updates:
Have proposed a fix in #860
