What version should `kotlinCompilerExtensionVersio...

What version should kotlinCompilerExtensionVersion be targeting? I always thought it should be the compiler version, but on the docs it shows that it can be 1.3.0-alpha01 a version that right above doesn’t seem to come from the compiler dependency since it only has the 1.2.0 stable release.
Am I misunderstanding something or is this a documentation bug?

I think this might be a docs bug...

[Stylianos Gakis]

Alright, that would make the most sense, do you want me to report it somewhere or can you take it from here?

[Ben Trengrove [G]]

I got it, all good

While we’re at it, I wonder then, if the compiler version is defined from kotlinCompilerExtensionVersion, does that mean that we shouldn’t then also explicitly depend on the compiler dependency?
And what happens if we somehow have two different versions on kotlinCompilerExtensionVersion and on the androidx.compose.compiler:compiler dependency? 🤔

Compose compiler is a compiler dependency (it’s added to the compiler plugins classpath). Adding it to app runtime classpath won’t have any effect.

[Stylianos Gakis]

Right…

it’s added to the compiler plugins classpath

And is this done automatically when defining the kotlinCompilerExtensionVersion? I know that it all still “just works” without adding it explicitly anywhere. For example the NiA app only reference to the compiler version is there and androidx.compose.compiler:compiler is not defined anywhere else.

[Albert Chang]

Yep.
