unresolved dependency: sbt-plugin

[azadbolour]

I am getting the following unresolved dependency in building my Scala Play
project:

[warn] Note: Some unresolved dependencies have extra attributes. Check that these dependencies exist with the requested attributes.
[warn] com.typesafe.play:sbt-plugin:2.8.7 (sbtVersion=1.0, scalaVersion=2.12)
[warn]
[warn] Note: Unresolved dependencies path:

My setup includes:

build.sbt with:
enablePlugins(PlayScala)
scalaVersion := "2.12.12"

build.properties:
sbt.version=1.8.2

plugins.sbt
logLevel := Level.Warn
resolvers += Resolver.sbtPluginRepo("releases")
addSbtPlugin("com.typesafe.play" % "sbt-plugin" % "2.8.7")

The same issue remains for version 2.8.0 of Play. And for version 1.3.13 of sbt.

How should I configure my project to access the needed play sbt plugin?

Many thanks.

This is caused by sbt/sbt#7202 and should now be fixed

[mkurz]

Should be back online now however.

Thanks for your prompt response.

My understanding is that the plugin should now be available under:

https://repo1.maven.org/maven2/com/typesafe/play/sbt-plugin_2.12_1.0/

However, the lowest version of the plugin there is 2.8.8. If I use that version, I get the following incompatibility:

[error] java.lang.RuntimeException: found version conflict(s) in library dependencies; some are suspected to be binary incompatible:
[error]
[error] 	* org.scala-lang.modules:scala-xml_2.12:2.1.0 (early-semver) is selected over {1.2.0, 1.1.1}

[error]
[error]
[error] this can be overridden using libraryDependencySchemes or evictionErrorLevel

And I am not sure what to do about that.

If the lower versions are no longer supported, can you advise on working around the above incompatibilities?

If lower versions are still supported, I was hoping to use version 2.8.7, or in case of issues, version 2.8.0. Could they be added to the repo?

Many thanks.

Do you use sbt 1.8.2 in your project/build.properties? If so try downgrading to 1.7.2 in that file and try again.

[joelhaasnoot]

There's also a note about how to fix this in the release guide for 2.8.19 https://github.com/playframework/playframework/releases/tag/2.8.19

[azadbolour]

Thanks for the tips. Using sbt 1.7.2 with play version 2.8.8 I was able to get my build to complete successfully.

Thanks again for the prompt responses. Much appreciated.
