Kotlin validation error have incorrect line numbers (and maybe column)

[wesbillman]

The build error shows Echo.kt:15:0

error:echo:build: Build failed: echo: /Users/wesbillman/dev/ftl/examples/kotlin/echo/src/main/kotlin/ftl/echo/Echo.kt:15:0: Invalid name echo-bogus stuff, must match ^[A-Za-z_][A-Za-z0-9_]*$

But the error is actually on line 12 in the IDE

Maybe add context to the messages to indicate what annotation it's referring to?
