I am struggling with StringBuilder. I have a common module which uses StringBuilder but I cannot call the function from the JVM module since java.lang.StringBuilder does not seem to be the actual type of it. What is the actual type in JVM?

[kpgalligan]

Can you post expect/actual code?

[robstoll]

I have no expect/actual, I am having something like:

fun foo(sb: StringBuilder){}

in common module and I want to call it from jvm module

[karelpeeters]

Where is the common StringBuilder decared?

[robstoll]

kotlin.text.StringBuilder

[robstoll]

Unfortunately I cannot search for implementations or rather intellij does not find them

[robstoll]

it seems like they missed to add actual to the type alias kotlin.text.StringBuilder in the JVM module

[kpgalligan]

Intellij doesn't see it, but doing a gradle build works

[kpgalligan]

In common, I have a var declared as follows:

[kpgalligan]

var sb : StringBuilder = StringBuilder()

[kpgalligan]

In jvm:

[kpgalligan]

sb = java.lang.StringBuilder()

[kpgalligan]

Intellij flags it, but it'll compile

[robstoll]

oh... interesting, I'll try it out

[robstoll]

you're right, works perfectly fine, I'll file a bug
