sbt has a compilation error when using this plugin

[nayakravi]

The error message is:
No implicit for Append.Value[Seq[sbt.librarymanagement.Resolver], com.lightbend.gcsplugin.GCSResolver] found,
so com.lightbend.gcsplugin.GCSResolver cannot be appended to Seq[sbt.librarymanagement.Resolver]
resolvers += GCSResolver.forBucket("bucket_name")

@nayakravi Could you elaborate on the use case for this ? Normally you would use the plugin by just adding it as a resolver and setting as a publisher
