KSP Error "IntrospectedTypeElementVisitor: keys must be sorted in ascending order"

[eratio08]

Hello, I'm currently trying to migrate a micronaut project from v3 to v4. I'm currently stuck with the following KSP exception

[ksp] Error finalizing type visitor  [io.micronaut.inject.beans.visitor.IntrospectedTypeElementVisitor@58a5b212]: keys must be sorted in ascending order

I'm not really sure what to do with this. Does anyone have a clue what to do in such a case?

[graemerocher]

can you provide an example in an issue report?

[dstepanov]

Please wait for 4.5 and test there

Using micronautVersion=4.5.0-SNAPSHOT yields the same issue

Can you pls attach the debugger:

kotlin {
    kotlinDaemonJvmArgs = ["-Xdebug","-Xrunjdwp:transport=dt_socket,address=5005,server=y,suspend=y"]
}

And see which of your beans is causing it. And post it's content.

[eratio08]

The class it's currently failing on is

import io.micronaut.context.annotation.ConfigurationProperties
import jakarta.validation.constraints.NotBlank

@ConfigurationProperties("some")
interface SomeProperties {
	@get:NotBlank
	val someString: String
}

removing the validation annotation will skip the error here each time and continue to another error with the same output but a different case (no validation annotation). I'm currently checking how to make it pass there.

[dstepanov]

The best case would be if you can reproduce it in the Core tests
