Is the EAP version of kotlin (1.4.20-M1) compatible with alpha04?

[Zach Klippenstein (he/him) [MOD]]

I think someone on the Compose team said last week that only 1.4.10 was compatible, or at least that’s the only one they’ve tested with.

[Robert Menke]

Gotcha. Tempted to give it a spin. This Unbound type parameters are forbidden error is impossible to track down haha 😅 .

[Afzal Najam]

It didn't work for me:

Hmm did it work for you with kotlin 1.4.10?

[Afzal Najam]

Yup

[Colton Idle]

Couldn't get 1.4.20 to work and someone from the compose team said that it shouldn't work IIRC. Scroll up a bit to find it if you're really curious.

Any luck with the Unbound type parameters error? It seems to have broken my build and I don't know how to fix it without waiting for an upgrade.

[Robert Menke]

I had to reorganize my code. Seemed to be an issue with me using the slot pattern. No clue why the compiler barfs with it my types are fine. Definitely annoying but that’s the price you pay with alphas.

[Brian Beale]

Well, that's confusing. Thanks for the context.

I seem to have gotten around that error (again) this time by simply commenting out my composables and then bringing them back in...

[Robert Menke]

Ya I would run into that as well but the error kept coming back so I had to find a work around. Very annoying. Seems to be some kind of non-deterministic compiler bug.
