Why do you need this?

for something like this: https://github.com/christophsturm/asserto/blob/master/src/test/kotlin/com/christophsturm/asserto/AssertoTest.kt#L27

The information is definitely in the class file (https://docs.oracle.com/javase/specs/jvms/se10/html/jvms-4.html#jvms-4.7.10). However I don't think you can get at it using reflection or similar terms. You'd have to get the raw class file bytes and read it using something like ASM... Not very practical.

thanks. i could just read the class file

try this:

val f = File(MyClass::class.java!!.getProtectionDomain().getCodeSource().getLocation().getPath())

yeah, i was pretty sure that was in there somewhere.

oh wow, thanks. i got it working by getting the path from the classfile, and then the filename from the stacktrace element

you can get it from the

.class

file as others mentioned above, but you'll have to either parse the .class file yourself or use a library that does it for you (Apache BCEL has that, I'm sure most other bytecode manipulation libs also do). BCEL implementation is here if you're curious : https://github.com/apache/commons-bcel/blob/trunk/src/main/java/org/apache/bcel/classfile/ClassParser.java

interesting!
