Unable to use the plugin due to unbound variable

[pamiel]

• What are you trying to do?
  Install the plugin and login to my Nexus repo.
  When running helm nexus-push my-repo login -u user, I receive an error /root/.helm/plugins/helm-nexus-push/push.sh: line 90: PASSWORD: unbound variable

• What feature or behavior is this required for?
  login to the Nexus repo using the plugin

• How could we solve this issue? (Not knowing is okay!)
  It looks to be due to the declaration of the PASSWORD variable: declare PASSWORD (https://github.com/sonatype-nexus-community/helm-nexus-push/blob/master/push.sh#L24)
  The issue is solved (workarounded ?) by adding an ending = to the declaration, ensuring that the PASSWORD variable is "set" before being acessed in line 90 of the script.
  For safety, I added the same ending = for lines 23 (USERNAME variable).
  Strangely, nothing bad happens for the similar declarations of variables CMD, AUTH, and CHART that I did not touched.

• Anything else?

Same error. Can not push in anonymous mode
If I push by specifying a user and a passord
helm nexus-push nexus mychart-0.2.1.tgz -u admin -p secret
I got another similar error :
.helm/plugins/helm-nexus-push.git/push.sh: line 126: AUTH: unbound variable

Hi,

Same error. My workaround is to set --password "". Not very clean but I can use login cmd to hide password

helm nexus-push nexus mychart-0.2.1.tgz --password ""

Same here.
I was trying to use my user/pwd declared with helm nexus-push login (neat !)

Script is failing due to the "-u" option specified with set -ueo pipefail when some undefined variables are tested.

Fixed it like by editing push.sh
On MacOS, `vi ~/Library/helm/plugins/helm-nexus-push.git/push.sh``

Changed this:

declare USERNAME
declare PASSWORD

with this

declare USERNAME=""
declare PASSWORD=""

in order to provide default values.
