🔧 Fix:

    // Fix Duplicate class
    implementation(platform("org.jetbrains.kotlin:kotlin-bom:1.8.0"))

}

krischik commented Mar 6, 2024

dependencies {
   implementation(platform("org.jetbrains.kotlin:kotlin-bom:1.9.22"))

Did the trick for me. So you might have to fine tune the statement.

Worked for me as well. Now could someone please explain why suddenly I'm getting build errors without it? And this "bom" dependency has to be added in every sub-library in the project.
I have not changed anything! literally, it's all in version control and no changes. Not in the project, at least. Something has changed in the system to cause this.
