I see this warning coming from KSP - is that from kotlinc under the hood or something in KSP? If so - could that also be suppressed?

w: Language version 1.5 is experimental, there are no backwards compatibility guarantees for new language and library features

As it prevents us from using warningsAsError

[Ting-Yuan Huang]

Somehow -language-version=1.5 is passed to the compiler. I'm not sure where it was set. It can be muted with -Xsuppress-version-warnings

[Zac Sweers]

ah great, thanks

[Ting-Yuan Huang]

IIRC KSP doesn't set the language version. Could it come from the project being built?

[Zac Sweers]

yeah I'm setting it to 1.5 for KotlinCompile tasks

[Zac Sweers]

also that flag doesn't seem to be available anymore

[Zac Sweers]

w: Flag is not supported by this version of the compiler: -Xsuppress-version-warnings
w: Language version 1.5 is experimental, there are no backwards compatibility guarantees for new language and library features
e: warnings found and -Werror specified

[Ting-Yuan Huang]

how did you add the flag? by adding it to free args?

[Ting-Yuan Huang]

I mean kotlinOptions.freeCompilerArgs

[Zac Sweers]

Yeah that’s where I tried adding it
