Errors when trying on a new project

[xelax]

I tried the plugin on a project of mine (sbt.version=1.3.3) and it fails with these errors:

missinglinkCheck Could not load META-INF/versions/11/org/roaringbitmap/ArraysShim.class from /Users/acozzi/Library/Caches/Coursier/v1/https/repo1.maven.org/maven2/org/roaringbitmap/shims/0.7.45/shims-0.7.45.jar Could not load akka/stream/javadsl/JavaFlowSupport$Flow$1.class from /Users/acozzi/Library/Caches/Coursier/v1/https/repo1.maven.org/maven2/com/typesafe/akka/akka-stream_2.12/2.5.26/akka-stream_2.12-2.5.26.jar Could not load akka/stream/javadsl/JavaFlowSupport$Flow.class from /Users/acozzi/Library/Caches/Coursier/v1/https/repo1.maven.org/maven2/com/typesafe/akka/akka-stream_2.12/2.5.26/akka-stream_2.12-2.5.26.jar Could not load akka/stream/javadsl/JavaFlowSupport$Sink.class from /Users/acozzi/Library/Caches/Coursier/v1/https/repo1.maven.org/maven2/com/typesafe/akka/akka-stream_2.12/2.5.26/akka-stream_2.12-2.5.26.jar Could not load akka/stream/javadsl/JavaFlowSupport$Source.class from /Users/acozzi/Library/Caches/Coursier/v1/https/repo1.maven.org/maven2/com/typesafe/akka/akka-stream_2.12/2.5.26/akka-stream_2.12-2.5.26.jar Could not load akka/stream/javadsl/JavaFlowSupport.class from /Users/acozzi/Library/Caches/Coursier/v1/https/repo1.maven.org/maven2/com/typesafe/akka/akka-stream_2.12/2.5.26/akka-stream_2.12-2.5.26.jar

Hi @xelax, and thanks for the report.

Could you please provide a minimized reproduction, in the form of a source file and a build.sbt, please? Currently I do not know how to reproduce the issue, so I cannot do anything about it.

Ok, it turns out it a doc mistake: 1) I copied the config from https://www.scala-lang.org/2019/10/17/dependency-management.html, where it says
addSbtPlugin("ch.epfl.scala" % "sbt-missinglink" % "0.1.0")

This leads to the error:

[error] stack trace is suppressed; run last Compile / missinglinkCheck for the full output
[error] (Compile / missinglinkCheck) scala.NotImplementedError: an implementation is missing
[error] Total time: 1 s, completed Oct 31, 2019, 10:35:26 AM

when I switch 0.2.0 for a very simple program created with

sbt new scala/scala-seed.g8

and adding addSbtPlugin("ch.epfl.scala" % "sbt-missinglink" % "0.2.0") into plugins.sbt I get:
