I'm trying to generate java client code using the following command

java -jar swagger-codegen-cli-3.0.2.jar generate -v  

        -i swagger.json 

        -l java

but I get the following error

java.util.NoSuchElementException: No value present

Any idea what is the issue ?

I fixed few errors in swagger file:

1. Path parameters not listed in the parameters collection (this was the root cause for above issue)


2. Parameters with invalid names (contains ! at the end or enclosed in {}) (this didn't cause an error at generation time but caused a compilation error)
