I am using scala in a production system. Recently a third party payment service provider updated its payment Java sdk, which caused this compilation error.

This is critical for our business. Please help ASAP. Thanks in advance.

We use Scala 2.12.4 and SBT 1.2.1

It's not easy to guess what the problem could be. I assume you did sbt clean? Can you check if the problem still shows up with Scala 2.12.7?

Yes I have run clean and also tried 2.12.7. Same compilation error.

Maybe the updated Java sdk is not binary compatible and some of your dependencies need to be re-compiled?

Is your project open-source? Or can you create a sample project that reproduces the issue?

My project isn't open source. I have created a very simple sbt project on github to reproduce it.
scala compilation error reproduce repo

The sdk source code is under src/main/java.

The sources for that project contain a Java class that extends itself.

The build is configured to have scalac typecheck the Java sources before javac (known as "joint Java/Scala compilation").

If we pass them to javac first with:

// build.sbt
...
compileOrder := CompileOrder.JavaThenScala

We see the error:

The error message you encountered is not user friendly, and should certainly be improved.

There seem to be a couple of errors. No package statement here. Is it only on MacOS that class names are case insensitive? I happen to be on a Mac.

If only case classes were case sensitive.

We should all be more class sensitive.

Thanks for pointing this out. I didn't know class name sensitivity with Java could be an issue. Found this on stackoverflow that discussed this in depth. jvm class name sensitivity

Strangely the code worked before SDK update. Any way differentiating class name by case sensitivity is bad.

Feel free to close the issue. Thanks.
