Key generation with a prebuilt jar

[oracle58]

Steps to reproduce

1. mkdir somedir
2. cd somedir
3. place the prebuilt jar in somedir
4. java -jar helix-<version>.jar -p 8085 -nominee <pathToSeed>

Issue

The Nominee.key file is automatically generated in and read from .src/main/resources, if this directory does not exist, following error is thrown:

java.io.FileNotFoundException: ./src/main/resources/Nominee.key (No such file or directory)

Expected behavior

If not run from the source repository, a resources directory should be created in the directory in which the jar is executed.
