I converted an old project from Scala 2 to Scala 3, but I can't seem to use enums. For instance, if I create an empty file with just
enum Color:
case Red, Green, Blue
I get the following error
[error] -- [E103] Syntax Error: .../eehh.scala:3:0
[error] 3 |enum Color:
[error] |^^^^
[error] |Illegal start of toplevel definition

[error] one error found
[error] (Compile / compileIncremental) Compilation failed
[error] Total time: 10 s, completed Jun 8, 2022, 2:41:47 PM
[IJ]scalaVersion
[info] 3.1.2
Even weirder is that enums seem to work fine in a fresh project. I have tried restarting the project, and even recloning a fresh version.
The sbt file is here: https://github.com/marklemay/calculus-of-constructions/blob/master/build.sbt .
I can't seem to find references to [E103] anywhere.

I have not changed my setup as far as I can see. As of today, trying to run sbt native packager with jlink gives this error:

How do I fix this? I tried adding javax.activation to libraryDependencies, that doesn't seem to have any effect or anything to do with this problem.
Edit: The root problem of seems to be my dependency on Pi4j 1.4, which depends on javax.xml.bind:jaxb-api which in turn depends on javax.activation:javax.activation-api. Now I don't understand much of this Java module stuff, but javax.activation-api does exist on Maven, so why does jdeps complain? If I exclude javax.xml.bind, it works, but now I'm worried I'm actually missing stuff on the class path.
javax.activation has been removed since java 11.
To fix it you can:
Download the javax.activation jar and run the command by adding this jar on module path:
jdeps --multi-release 11 -R --module-path path\to\javax.activation.jar ...
Running this command with java 8 jdeps
I'm trying to build kafka-connect-hdfs by following this FAQ.
While trying to compile schema-registry, I get the following error:

Are any modifications required? Appreciate any suggestions. Thanks
I am trying to upgrade to the newly released guava-gwt 20. I am getting this exception when I do a gwt compile. I did not get any errors prior to upgrading to guava 20. I am using the gwt 2.8.0. Is there a module I need to reference? Much appreciated!

This appears to be a Guava bug. Until we fix it, you can work around it by adding <inherits name="java.lang.Lang"/> to your .gwt.xml.
My simple Play 2.4 project does not compile when I rename the conf/routes file to something else, e.g. conf/hello.routes. The reason I'm doing this is to enable composition of APIs while allowing them to be developed in separate git repositories and sbt projects.
The idea of multiproject support is based on this project and blog post - but that's using Play 2.3.
The error I get is:
$ sbt test
...
[info] Hello should
[error] ! give {hello: true}
[error] Unable to provision, see the following errors:
[error]
[error] 1) Error in custom provider, java.lang.ClassCastException: interface play.api.routing.Router is not assignable from class hello.routes

Got this resolved (code in the git repo now works).
The problems were likely connected to both of these:
the Controller implementation wants to be within a package controllers.hello instead of just hello
in the application.conf file one should omit the controllers namespace, i.e.
play.http.router = app.Routes
I learned this simply by comparing this code with samples that work.
I am trying to compile a GWT project but I am getting the following error: Can anyone please explain if I am missing anything? I have downloaded the GWT plugins for the eclipse.
