would it be worth a feature request to have a more specific warning for this/not break -Werror? Since it's controlled at the gradle level it's not possible to suppress this warning without suppressing warnings for all elements in the project

w: K2 kapt is in Alpha. Use with caution.
e: warnings found and -Werror specified

[eygraber]

But breaking -Werror is a tradition!

You can describe your situation in KT-73571

BTW the specific problem with warning about K2 KAPT will be gone in 2.1.20, as we switched the default

-Xsuppress-version-warnings

[Zac Sweers]

thanks, and will do

[Zac Sweers]

@udalov that flag doesn't actually appear to change anything in 2.1.0 when I test it. The generate stubs task still emits a warning

[udalov]

Are you sure you've applied it to the correct task?

[Zac Sweers]

yes, applied on the generate stubs task, which is the one that emits the warning

[udalov]

And no other code modifies freeCompilerArgs for this task?

[Zac Sweers]

not in a destructive way, no. Append-only

[udalov]

I have no idea how that's possible. The warning was literally guarded on the condition of there being no -Xsuppress-version-warnings in the compiler arguments. If you feel adventurous, you can dump compiler arguments by passing --debug to Gradle (output to file since it's very large) and try looking for it there. But anyway, this warning is removed in 2.1.20.

Adding the flag like this doesn’t work for me

tasks.withType(org.jetbrains.kotlin.gradle.tasks.KaptGenerateStubs.class).configureEach {
    compilerOptions {
        freeCompilerArgs.add("-Xsuppress-version-warnings")
    }
}

But adding it globally through the extension works

kotlin {
    compilerOptions {
        freeCompilerArgs.add("-Xsuppress-version-warnings")
    }
}

I’ve checked the debug logs and only in the second case -Xsuppress-version-warnings was in the compiler args

[Zac Sweers]

Iiiinteresting. Yeah I did it through the task directly as well
