Why does

@Component
class Foo {
    inline fun foo() {}
}

gives me
inline' modifier is not allowed on virtual members. Only private or final members can be inlined

Perhaps you're using the Kotlin Spring compiler plugin? That will make @Component classes and their public members open by default, to allow Spring to do its thing. That would explain why foo is not being treated as a final function.

[Sourabh Rawat]

Yea, that seems to be the case. But I was hoping for finding some way to support inline functions in an open class as well, at least when interacting with spring

[Sam]

Just mark the function as explicitly final

[Sam]

@Component
class Foo {
    final inline fun foo() {}
}
