Question

Trying to enable compose in my project I m not actually using it anywhere and I ve been waiting for alpha08 because of kotlin 1 4 20 support and this is the error I get ```androidx compose compiler plugins kotlin IncompatibleComposeRuntimeVersionException You are using an outdated version of Compose Runtime that is not compatible with the version of the Compose Compiler plugin you have installed The compose compiler plugin you are using version 1 0 0 alpha08 expects a minimum runtime version of 1 0 0 alpha08 ``` Anyone else get this

This is all I m adding to my app level build gradle ```kotlinOptions jvmTarget = 1 8 useIR = true buildFeatures compose true viewBinding true composeOptions kotlinCompilerVersion 1 4 20 kotlinCompilerExtensionVersion 1 0 0 alpha08 ``` root level build gradle was changed to this ```classpath com android tools build gradle 7 0 0 alpha01 classpath org jetbrains kotlin kotlin gradle plugin 1 4 20 ``` and gradle was updated to 6 7 1 I ve tried cleaning building etc Any other debugging steps I can take here

Did you not update the actual `implementation` clauses

Colton Idle · Answer

< jaqxues> I m not actually using anything compose related yet I m just trying to enable it in general So I have no deps with `implementation` yet < jim> or < Leland Richardson G > any ideas

Do you have anything else in your build files that mentions `alpha07` In particular what is your `androidx compose runtime runtime` dependency version

Colton Idle · Answer

< jim> I don t have any reference to androidx compose runtime I literally took my existing project and followed the docs to add compose so all I added was really this ```kotlinOptions jvmTarget = 1 8 useIR = true buildFeatures compose true viewBinding true composeOptions kotlinCompilerVersion 1 4 20 kotlinCompilerExtensionVersion 1 0 0 alpha08 ``` and that s enough to not allow me to compile

Colton Idle · Answer

< jim> that was the issue sob I simply added `implementation androidx compose runtime runtime 1 0 0 alpha08 ` and it worked Someone should really clarify in the Add Jetpack Compose to an existing project what is mandatory and what s not smile It tells you have to configure kotlin and gradle but the toolkit dependencies seem optional tooling previews material etc No mention of `androidx compose runtime runtime `
