There was a problem hiding this comment.
Ideally there should not be any warning if the url is the current (github) index or the uri host is *.seqera.io

This adds an implementation of p4fj's
UpdateRepositorywhich can download plugin metadata from an http api.It also adds a new interface
PrefetchUpdateRepositorywhich extends p4fj's interface to add aprefetch()method. When initialising plugins, Nextflow will call this prefetch method on any UpdateRepository which implements this interface, allowing the repository to optimise how it downloads plugin metadata (for example, only loading metadata for required plugins rather than for all plugins).Use of the new http update repository can be enabled with the new
NXF_PLUGINS_INDEX_URLenvironment variable. If set, this overrides the defaultindexUrllocation of theplugins.jsonmetadata file. If the supplied url ends in.jsonthen Nextflow will use the existing update repository implementation, otherwise it will use the new http api implementation.Unless this new env var is set, these changes should have no effect on Nextflow's behaviour.
