-----------------------------------------
Hi Jorge,
Ok, I think I finally figured out a what reproduces it: make sure you have an
empty `src/test/java` directory (but making sure you have one or more Java
files to compile under `src/main/java` and then use the following pom:
{noformat}
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

> I didn't catch this earlier since I don't use Kotlin and on a normal project,
> this should not be an issue since the javac documentation mentions that the
> directory, and any necessary subdirectories, will be created if they do not
> already exist.
> But on a somewhat modified project that compiles kotlin source code, this
> triggers an issue on plexus-compiler where the generated-soruces directory
> does not exist.
>
> This might be related to issue MCOMPILER-538, where it claims that generated
> source root is not required for javac, but additional confirmation is
> required.
>
> The fix will be to create the generated sources directory to preserve the
> current behavior.
