Issue appears to be due to a missing template dir. The following line returns null for config.templateDir().

swagger-codegen/modules/swagger-codegen/src/main/java/io/swagger/codegen/v3/AbstractGenerator.java

Line 96 in 2807c71

final String template = config.templateDir() + File.separator + templateFile;

should be fixed in swagger-api/swagger-codegen-generators#214. Closing ticket, please reopen if still experiencing issues.
