Scala 2.13 variant of the bloop plugin for Gradle is not available

[q10]

We have several projects that use gradle for our builds, and one of the gradle plugins that we depend on has recently updated its dependency on org.scala-lang:scala-library from 2.12.x to 2.13.x. This ends up breaking the gradle bloop plugin (currently dependent on Scala 2.12.x), where any task launched with ./gradlew immediately fail with the following compatibility error (abridged):

Caused by: java.lang.NoSuchMethodError: 'scala.collection.GenTraversable scala.collection.Seq$.empty()'

I did not find a 2.13 variant of the bloop plugin for Gradle, though I see 2.13 variants available for maven and sbt. Can we get a 2.13 variant of the bloop plugin for Gradle published?

Hi @q10!
Indeed, there is no 2.13 Gradle plugin. I'll take a look at this.

@q10 Could you try 1.4.13-70-d6f16202? I cross-compiled plugin in #1717.

Hi @kpodsiad. I have tried a fresh ./gradlew build from my project and with bloop_2.13:1.4.13-70-d6f16202 specified, Gradle is able to run again without throwing exceptions. Thanks for the update!

Glad to hear that it works @q10!

By the way, do you use bloop with Metals or Intellij?
