To Reproduce
try to run compileKotlinIosSimulatorArm64 task for KMP project

Expected behavior
Compilation tasks is successful

Additional context
The library works fine on Android. The dependency was added in: commonMain.dependencies {} block. Compiler version: 2.1.0.

Hi @lkjh654, thanks for the report. I do not have a mac, so it is hard for me to reproduce.

I do have a strong suspicion that this is fixed in the master branch, in which it is no longer required to explicitly add the mappie-api dependency. I will add an explicit error message, instead of a generic exception for when this problem occurs.

I will create a release for 1.0.0, can you give that version a try when it's released?

[lkjh654]

I will! :)

[stefankoppier]

After some trouble with JReleaser, I managed to release 1.0.0

[lkjh654]

After bumping version to 1.0.0 I'm getting another exception during compilation for iOS:

e: Compilation failed: While analysing /XXX/KoinModule.kt:12:29: java.lang.NoClassDefFoundError: tech/mappie/api/config/UseStrictVisibility

It still works fine on Android

[stefankoppier]

That's sad to hear. The exception has the same cause: the compiler plugin cannot find the dependency at compilation time, only at a different point of execution.

Does it work if you add the mappie-api dependency explicitly for iOS? Either way, this is a bug. I will look into it as soon as possible.

[lkjh654]

Adding tech.mappie:mappie-api:1.0.0 to iosMain.dependencies changes nothing - there is still a compilation error (the same one as above).

HI @lkjh654. The issue is fixed. It is planned for release 1.1.0.

I wasn't able to reproduce for ios but mingwx64 had the same issue. If an issue remains on ios, please re-open this ticket.

[lkjh654]

Thanks for the update! When is 1.1.0 release planned? I'd like to test the fix.

[stefankoppier]

@lkjh654 I just made a release 🙂
