Hello,
I'm currently trying to implement the moko-resources but I keep receiving the gradle error: Required value was null.

hello!
strange error, because you have configure required value...

please run gradle build with --stacktrace flag.

./gradlew assemble --stacktrace for example

* What went wrong:
Cannot convert the provided notation to an object of type Dependency: MultiPlatformLibrary(android=null, common=dev.icerock.mokoresources0.13.1, iosX64=dev.icerock.mokoresources iosx640.13.1, iosArm64=dev.icerock.mokoresources iosarm640.13.1).
The following types/formats are supported:
- Instances of Dependency.
- String or CharSequence values, for example 'org.gradlegradle core1.0'.
- Maps, for example [group: 'org.gradle', name: 'gradle-core', version: '1.0'].
- FileCollections, for example files('some.jar', 'someOther.jar').
- Projects, for example project('someproject:path').
- ClassPathNotation, for example gradleApi().

@alex009
I have uploaded a sample project to github:
https://github.com/frodob/MokoResourcesTest

[alex009]

https://github.com/frodob/MokoResourcesTest/pull/1/files here fixes

[Julius]

Awesome! Thank you very much!

[Julius]

@alex009
Almost there, but I think I'm still missing something.
The auto-generated MR file is missing the actual implementation for iOS:
Expected object 'MR' has no actual declaration in module MokoResourcesTest.SharedCode.iosArm64Main for Native
Expected object 'MR' has no actual declaration in module MokoResourcesTest.SharedCode.iosX64Main for Native

[alex009]

code generates when you compile specific target. if you want to generate actual manually - run generateMRiosX64Main gradle task
