[Cucumber] Getting NullPointerException, when executing cucumber from command prompt.

Hi,

I am getting the below exception, when tried to run cucumber from the command prompt.

C:\workspace\cucumber\checkout>java -cp "jars/*;c:/workspace/cucumber/checkout/features/step_definitions/" cucumber.api.cli.Main -p pretty --snippets camelcase \ -g step_definitions features

Exception in thread "main" java.lang.NullPointerException

Please guide me on this.

By reading the code, it looks like the only ways to have a NPE there is:
- security manager blocking access to the directory
- path name containing null character (that shouldn't be your case)

...so I'd check the security manager grants Cucumber-JVM read access
to the file path.
