[sbt-1.3.0-RC3] custom resolver not used for resolving plugin dependencies

[2m]

steps

sbt version: 1.3.0-RC3

When a plugin is added to the global configuration that needs a custom resolver, plugin dependencies are not resolved.

For example, given such global configuration:

~/.sbt/1.0/plugins/build.sbt
---------------------------------
addSbtPlugin("lt.dvim.authors" % "sbt-authors" % "1.0.2")
resolvers += Resolver.bintrayRepo("jypma", "maven") // for ts-reaktive

Any project fails to load with the following error:

[error]   Not found

problem

Custom resolver is not considered when resolving global plugin dependencies.

expectation

Plugin dependencies should be resolved using the custom resolver.

notes

If such plugin and resolver are added to the local project build (./project/plugins.sbt) then project loads successfully.

@2m Thanks for the report!

I wonder if this is still reproducible on current sbt.
