I trying to run simple plugin from cli. My interpretation of docs is like this kotlinc hello.kt -include-runtime -Xplugin=kotlin-ir-plugin-0.1.0-SNAPSHOT.jar -Xuse-ir -d hello.jar
But I am gettng error

Jar file for plugin has been built with gradle from template project by @bnorm https://blog.bnorm.dev/writing-your-second-compiler-plugin-part-1 and units tests are runnign as expected.

If I do the same with a compiler-plugin jar from a module for Kotlin native, it works, plugins gets loaded and makes nice dumps 🙂 I am confused, how can I tell to kotlinc to be a jvm compiler not Kotlin/native.A result of compilation is jar file with I can run with java -jar hello.jar. I am almost sure, that Kotlin/native is even not installed, I am using dockerized kotlinc downloaded directly from github releae page...

I'm assuming kotlinc -version matches the compiler dependency of your plugin? That would be my first guess

[rnett]

You can also use kotlinc-jvm to force jvm backend (it should be default though, afaik)

[Michal Harakal]

The first error message suggests that it could be because of different compiler versions, but Kotlin/Native variants built the same way works, I would expect none of them working. I also also experimented with Java versions. AFAIK, one of the differences between Kotlin-jvm and Kotlin/native which are quite well described in the mentioned blog, is a package name for MockProject which in the second error on bottom in my stack trace

[rnett]

Yeah, but if I remember right, they matched at some point, but then JVM changed and native didn't, so you would see the same (or at least similar) error on an old JVM backend. It's more of a "first thing to check", anyways, the only other thing I can think of is that the template doesn't specify a kotlin-compiler-embeddable version, which (I think) picks it up from the build plugin, so make sure your CLI is 1.4.30.
