Getting an error when trying to run a quarkus app in dev mode with scala 3

[costa100]

This is the error I get:

Exception in thread "main" java.lang.RuntimeException: java.lang.AbstractMethodError: Receiver class io.quarkiverse.scala.scala3.deployment.Scala3CompilationProvider does not define or inherit an implementation of the resolved method 'abstract java.nio.file.Path getSourcePath(java.nio.file.Path, io.quarkus.paths.PathCollection, java.lang.String)' of interface io.quarkus.deployment.dev.CompilationProvider.

Any ideas?

Thank you

I found this:

    @Override
    public Path getSourcePath(Path classFilePath, PathsCollection sourcePaths, String classesPath) {
        return classFilePath;
    }

Note the second parameter PathsCollection. The parameter in the interface method is PathCollection.

[costa100]

Ok, that is the fix, i.e. removing the letter s from PathsCollection. I downloaded the code, made the change, built the quarkus-scala3-0.0.2-SNAPSHOT.jar jar file (runtime), deployed it to a local maven repo using the info from this SO: https://stackoverflow.com/questions/4955635/how-to-add-local-jar-files-to-a-maven-project/36602256?answertab=modifieddesc#tab-top, and it works.

[arkaprovob]

Any update on this? facing the same problem.

[msogrin]

If the fix is known, can it be delivered and a new version published?

I created a PR to upgrade to Quarkus 3 and fix this issue in passing: https://github.com/quarkiverse/quarkus-scala3/pull/9
