Cannot configure KMP project with JS target

Build Environment SQLDelight version: 1.5.0 OS: Windows Gradle version: 7.0.1 Kotlin version: 1.5.0 AGP Version (if applicable): N/A

Example: project-2.zip

Describe the bug

1. This project contains a few modules for a KMP project. For simplicity’s sake there is no source code, only the gradle files.
2. The app/build.gradle file line 18 adds com.squareup.sqldelight:gradle-plugin:1.5.0 to the classpath.
3. When I try to launch any tasks from gradle I get the error:

Caused by: java.lang.IllegalStateException: The Kotlin Gradle plugin was loaded multiple times in different subprojects, which is not supported and may break the build. 
This might happen in subprojects that apply the Kotlin plugins with the Gradle 'plugins { ... }' DSL if they specify explicit versions, even if the versions are equal.
Please add the Kotlin plugin to the common parent project or the root project, then remove the versions in the subprojects.
If the parent project does not need the plugin, add 'apply false' to the plugin line.

1. If I were to remove the classpath, the project configures and compiles correctly. Otherwise if I remove the JS target in gradle/mpp-lib.gradle, the project is also able to configure and compile.

Yeah they don’t have to be, but it’s safest to do it that way because of problems like this.

Going to close. Thanks for looking @dellisd!

That makes sense. Thanks for the insight.
