I have two files named `Extensions.kt` in the same package but in two different modules. Maven compiles everything successfully but when running it it suddenly can't find some of the extension methods. Is that a bug?

Not a bug. That's how the JVM works. First one on the classpath wins.

You could use multiple filenames, or if you really want to keep the same filename, the annotation `@JvmName("Extensions1")` at the top of the file (I think technically on the `package` statement?) will let you have multiple `Extensions.kt` files, that produce `Extensions.class` and `Extensions1.class` binaries, solving your classpath issue
