Adding bloop results in Boxed Exception

[maver1ck]

I'm trying to use mill in Metals. Mill version: 0.7.3. This needs bloop to be installed. Both manual and automatic installation failed with Boxed Exception.

build.sc

import mill._
import mill.scalalib._

import $ivy.`com.lihaoyi::mill-contrib-bloop:0.7.3`

object main extends SbtModule {
  def scalaVersion = "2.13.2"
}

$ mill mill.contrib.Bloop/install                                  
Failed to resolve ivy dependencies:Boxed Exception
