The Bitbucket plugin does not appear to retain custom port/protocol configurations for Bitbucket Server. Instead it always defaults back to HTTPS/port 443.

I am trying to connect to an internally-exposed Kubernetes service endpoint http://bitbucket-svc:7990.

I can connect to the endpoint at the Manage System configuration page and even when I'm creating my Jenkins pipeline job. However, when I try to build the project, I can see in the logs it's connecting via HTTPS.

Steps to replicate:

• Configure the Bitbucket server location to use the default Bitbucket HTTP port 7990.
• Connect successfully from Manage System and pipeline job configuration
• Click "Build Now" and observe the protocol/port the plugin tries to connect to
