After upgrading to lifecycle-viewmodel:2.5.0-alpha01 I’m getting compile errors on classes that inherit from `ViewModelProvider.Factory`:

Inheritance from an interface with ‘@JvmDefault’ members is only allowed with -Xjvm-default option

I’ve tried fiddling all -Xjvm-default=xxxxx options but the error does not go away.

Anyone had the same trouble?

Oooh. I Just got this too after updating. Any luck yet @julioromano?

The only additional info I could find is here https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.jvm/-jvm-default/ where there are more option on that flag, but I tried setting them all with no luck. 🤷

think I figured it out. In the module with the problematic code... add

tasks.withType<org.jetbrains.kotlin.gradle.tasks.KotlinCompile> {
    kotlinOptions {
        freeCompilerArgs += "-Xjvm-default=enable"
    }
}

Weird, I tried that too and it kept failing. In the end I reverted to 2.4.0 🤷

I initially put it in my root build.gradle and it didn't work. If you put it in your root you have to surround it with subProjects

Also, be sure to have -Xjvm-default=enable NOT -Xjvm-default (which I know you said you tried. just highlighting for others in the future)
