Jfrog artifactory missing project key option

[selvakarthik87]

Hi team. We are creating jfrog artifactory with in projects inside jfrog.

When I want to upload the file into the artificatory, we need to give project key for that artifactory.

But, as per the example given there is no option to give project key while building artificatory object using this.

Any help or example how to set project key while building artificatory would be helpful.
Thanks in advance.
