Currently the content-package Plugin only works with SSL if the Certificate is trusted.
This brings up some problems with self-signed certificates used on several testing system.s
It would be helpful to have an (optional) parameter to also allow self-signed certificates.
The code-changes would involve the getHttpClient() method and an optional parameter.
If you could provide a fitting parameter name, I'd be happy to create a pull-request for this. How about: vault.trustSelfSigned ?
