expectation

Now, the POM truly is missing for some reason, but it worked just fine with 1.2.8

sbt version: 1.3.0-RC1

@Katrix Thanks for the report!

The error message says:

[error] Conflicting dependencies:
[error] org.webjars.npm:is-number:2.1.0:default(compile)
[error] org.webjars.npm:is-number:4.0.0:default(compile)

I suggest you override the version for those conflicting dependencies - https://www.scala-sbt.org/1.x/docs/Library-Management.html#Overriding+a+version
or use Ivy instead.

ThisBuild / useCoursier := false

I'm hitting this as well in SBT 1.3.0-RC3 and dependencyOverrides don't seem to resolve the issue.

[joan38]

I tried something like:

dependencyOverrides += "org.webjars.npm" %% "kind-of" % "6.0.0"

But it doesn't work any idea?

[eed3si9n]

That sounds concerning.

@alexarchambault dependencyOverrides should be able to resolve any conflicts, right?

@alexarchambault @eed3si9n Reproduction steps:

touch build.sbt
mkdir project
cat > project/plugins.sbt << EOF
addSbtPlugin("com.github.gpgekko" % "sbt-autoprefixer" % "1.2.0")
dependencyOverrides ++= Seq(
  "org.webjars.npm" % "is-number" % "4.0.0",
  "org.webjars.npm" % "kind-of" % "6.0.0",
  "org.webjars.npm" % "string-width" % "2.0.0",
  "org.webjars.npm" % "strip-ansi" % "4.0.0"
)
EOF
echo "sbt.version=1.3.0-RC3" > project/build.properties
sbt update

Seems to be an issue with the wiring of sbt with coursier. It's an issue with the sbt-lm-coursier plugin too, that's very similar to the coursier integration in sbt.
