False positive kotlin.stdlib.default.dependency warning

[mgroth0]

What happened?

My build gets this warning:

The dependency on the Kotlin Standard Library (stdlib) is automatically added when using the Gradle Kotlin plugin and may conflict with the version provided with the IntelliJ Platform, see: https://jb.gg/intellij-platform-kotlin-stdlib

This is a false positive, as my project does have this line in its gradle.properties file:

kotlin.stdlib.default.dependency=false

This is a gradle subproject, not the root project. I have tested and confirmed that setting kotlin.stdlib.default.dependency=false in a subproject gradle.properties file has the intended effect. However, this code from the plugin is causing a bug:

        kotlinStdlibDefaultDependency.convention(
                    project.providers
                        .gradleProperty("kotlin.stdlib.default.dependency")
                        .map { it.toBoolean() }
                )

This property above should return a value of "false", but instead it returns "true". And the reason why is gradle/gradle#24491 and gradle/gradle#23572.

Steps to reproduce

1. Create an IntelliJ plugin module as a subproject
2. Give it a gradle.properties file with kotlin.stdlib.default.dependency=false. Make sure this is in the subproject folder.
3. Expect no warning, but observe warning.
