Gradle's api & compileOnlyApi configurations created by its java-library plugin do not work, and transitive implementation scope dependencies get exposed, when this plugin is used

[AlexanderBartash]

What happened?

Gradle's java-library plugin is more suitable for IntelliJ plugin development than regular java. I think it must be supported, since it a basic Gradle feature.
See:

• https://docs.gradle.org/current/userguide/java_plugin.html
• https://docs.gradle.org/current/userguide/java_library_plugin.html

Sub-issue:

• If you look carefully at the output on the screenshot below, you will see that org.apache.commons:commons-lang3:3.5 was exposed as a transitive dependency though implementation dependency scope, which is not supposed to happen. It is bad.

The setup:

build.gradle.kts

plugins {
    `java-library`
    //id("org.jetbrains.kotlin.jvm") version "2.0.20"
    id("org.jetbrains.intellij.platform") version "2.1.0"
} 

dependencies {
    implementation(project(":subpr"))
}

repositories {
    mavenLocal()
    mavenCentral()
}

settings.gradle.kts

rootProject.name = "123"

pluginManagement {
    repositories {
        mavenLocal()
        mavenCentral()
        gradlePluginPortal()
    }
}

include(":subpr")

subpr/build.gradle.kts

plugins {
    `java-library`
    //id("org.jetbrains.kotlin.jvm") version "2.0.20"
    id("org.jetbrains.intellij.platform.module")
}

repositories {
    mavenLocal()
    mavenCentral()
}

dependencies {
    compileOnlyApi("org.jetbrains:annotations:26.0.1")
    implementation("org.apache.commons:commons-lang3:3.5")
}

Expected result:

• org.jetbrains:annotations:26.0.1 is available to the root project transitively from the sub project.

Actual result result:

• It is not, while what should not be available (org.apache.commons:commons-lang3:3.5) is there.
  

If kotlin plugin is added to the sub-project, somehow it starts working, but implementation is still exposed:
