Issue with 8.0.0-RC

[pambrose]

When trying to upgrade to 8.0.0-RC, I am seeing the same issue in the address-fullstack-ktor example and my own code. When I do a build on address-fullstack-ktor I get:

e: file:///git/kvision-examples/addressbook-fullstack-ktor/build/generated/ksp/metadata/commonMain/kotlin/com/example/AddressService.kt:10:8 Class 'AddressService' is not abstract and does not implement abstract member 'getAddressList'.
e: file:///git/kvision-examples/addressbook-fullstack-ktor/build/generated/ksp/metadata/commonMain/kotlin/com/example/ProfileService.kt:10:8 Class 'ProfileService' is not abstract and does not implement abstract member 'getProfile'.
e: file:///git/kvision-examples/addressbook-fullstack-ktor/build/generated/ksp/metadata/commonMain/kotlin/com/example/RegisterProfileService.kt:10:8 Class 'RegisterProfileService' is not abstract and does not implement abstract member 'registerProfile'

Thanks.

That's strange. I've tested all the examples and they are building without problems on my machine. I've also upgraded some other apps without such issues as well.

[pambrose]

Interesting!!
I tried Java 11, 17, and 21 and all 3 had the same issue. I invoked build from the CLI and IJ.
Let me try it on a different machine.

Have you fresh cloned kvision-examples repo?

[pambrose]

I do.
My original problem was on OSX. I just went to a Linux box and did a fresh clone and a build on address-fullstack-ktor and I got the same errors.
This is really bizarre!

I got a similar error in numbers-fullstack-ktor:
e: file:///git/kvision-examples/numbers-fullstack-ktor/build/generated/ksp/metadata/commonMain/kotlin/com/example/NumberService.kt:10:8 Class 'NumberService' is not abstract and does not implement abstract member 'numberToWords'.

Sorry, I am a dope. I was using build and not jar. Sorry for wasting your time. All good.

[rjaros]

Still that's interesting why the compileCommonMainKotlinMetadata task (executed by build) is failing. It seem to fail on compiling Kotlin file, which obviously is correct.

[rjaros]

I've asked a question in the slack channel. Perhaps someone will explain the issue.
