I don't know why it's not building. I just updated AS to canary 9. This was showing that the bundled Kotlin library is old, so I updated it to 1.3.72. Now, it says that it differs with the bundled version. Also, the Compose plugin is incompatible

I had a variety of problems when I tried upgrading to Canary 9, so I'm still on Canary 8. In terms of the Kotlin version, back when

dev10

was released, there was some discussion that I think settled on "stick with

1.3.70

for now".

Oh, I was so excited to try out Compose :( I will wait for a new update than downgrading

I’m using Canary 9, it shows same error, but it works. I guess you can ignore it
