Hi,

I am trying to modify a plugin which worked on 7.x to the new APIs for 8.x

I am trying to update a line in the plugin, specifically:  
`scmService.getCommandFactory(repository).heads(refs::add).call();`

`heads` has been [deprecated](https://docs.atlassian.com/bitbucket-server/javadoc/7.14.0/spi/com/atlassian/bitbucket/scm/PluginCommandFactory.html#heads-com.atlassian.bitbucket.repository.Repository-com.atlassian.bitbucket.repository.RefCallback-):

I can’t figure out the replacement which says to use `RefsCommandParameters`

I am just looking for an example of `RefsCommandParameters` to complete the change as follows:  
`scmService.getCommandFactory(repository).refs(refsCommandParameters, refCallback).call();`

It looks to be a Builder but I have no idea what parameters to use.
