"Packages and file facades are not yet supported in Kotlin reflection. Meanwhile please use Java reflection to inspect this class" #682

charleskorn · 2019-05-01T08:49:55Z

I've just tried to update https://github.com/charleskorn/kaml to use Spek 2.0.3 and I'm getting this error when running the tests through Gradle:

Interesting, the exception happens here: https://github.com/spekframework/spek/blob/2.x/spek-runner/junit5/src/main/kotlin/org/spekframework/spek2/junit/SpekTestEngine.kt#L52. What kotlin and JVM version are you using?

charleskorn · 2019-05-01T11:19:54Z

Kotlin version is 1.3.31.

Java version:

java version "1.8.0_162"
Java(TM) SE Runtime Environment (build 1.8.0_162-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.162-b12, mixed mode)

raniejade · 2019-05-01T22:34:58Z

Most probably the JVM version, I'm using JDK10 at home. Is JDK 8 a requirement for you? Is it possible to use JDK 10 but set the compilation target to Java 8?

charleskorn · 2019-05-02T08:52:42Z

Just tried with JDK 11 and got the same error. Anything else you'd like me to try?

raniejade · 2019-05-02T12:08:27Z

All good, thanks for the help! I'll try to replicate it.

raniejade · 2019-05-04T08:06:56Z

@charleskorn can you try dev build: 2.1.0-alpha.0.1+026f046?

charleskorn · 2019-05-04T11:40:54Z

Tried that with https://github.com/charleskorn/kaml and now I'm getting:

Can I suggest adding some unit tests around this code? It seems to be a recurring source of issues.

Can I suggest adding some unit tests around this code? It seems to be a recurring source of issues.

I added some tests before but it does not catch all cases. Can you show me which class is causing the problem?

charleskorn · 2019-05-04T22:29:19Z

It looks like it's the companion to Container defined at https://github.com/charleskorn/kaml/blob/master/src/test/kotlin/com/charleskorn/kaml/YamlTest.kt#L1034

raniejade · 2019-05-05T00:50:38Z

I'll post in another build once #687 is merged. So sorry for the trouble!

raniejade · 2019-05-05T01:56:40Z

Build finished, can you try 2.1.0-alpha.0.3+45afbe2 out?

charleskorn · 2019-05-05T11:01:57Z

Looks like it's working, thanks!
