Can't use breeze is Scala 3.1.0

[Swoorup]

When I try to use this library in Scala 3 I get the following issue:

I am using cats-effect, spire already as is. Not sure if the cross-compilation is setup correctly.

error] Modules were resolved with conflicting cross-version suffixes in ProjectRef(uri("file:/Users/swoorup.joshi/personal/finflow-scala/"), "common"):

Can be fixed by https://github.com/scalanlp/breeze/pull/833

Hi @dlwh Any chance for a new release? The last version in scaladex appears to be 10 months ago. https://index.scala-lang.org/scalanlp/breeze/artifacts/breeze?binary-versions=_3#

[dlwh]

doing it as we speak!

Ok 2.1.0 should be hitting central as we speak.

Awesome

Not sure why, but I'm getting what appears to be this error when I try to upgrade breeze version from "2.0.1-RC2" to "2.1.0". On the off chance that someone can see a relevant clue in my stack dump:

My build compiles for "2.13.8" and "3.2.0", and there's no problem with the scala2 build. Here's what happens during the scala3 compile:

I verified that the transitive dependency on spire is from breeze.

[dlwh]

Can you use one of the SBT dependency tree plugins that are out there different the dependency graph I suspect the conflict will be pretty clear in there

Wow, thanks! I did try that previously, but this time it showed that I have a conflict with circe, which requires an older version of cats-kernel.
