Getting below error while updating the compose-ui version to 1.4.0-aplha05
Kotlin version : 1.7.20
compiler version: 1.3.2
P.S. : 1.4.0-aplha04 works fine.
Any help is appreciated, thanks!!

This is just a wild guess but you are still using Kotlin 1.7.20 but 1.40-alpha05 seems to be built with 1.8.0. In Kotlin 1.8.0 they have merged the various variants of the stdlib into one. Maybe you are puling in the old variants and the new merged one and thus get this conflict. As I said - just a wild guess.

I’d say bump to Kotlin 1.8, and compose compiler to 1.4.0 (for kotlin compatibility) and then try again. If it persists then it’s a problem. Otherwise I’m guessing it’s exactly what Michael said.

[Gagan Deep]

thanks, but no where in release notes its mentioned that kotlin 1.8 is required for 1.40-alpha05 , will check with 1.8
