i’m really struggling to get the versions of kotlin aligned on my project.

i have:

dependencies {
    implementation(enforcedPlatform("org.jetbrains.kotlin:kotlin-bom:1.5.10"))
    ...
}

but when i run gradle dependencies i see all sorts of nonsense like:

+--- org.jetbrains.kotlin:kotlin-reflect:1.4.31 (*)
+--- org.jetbrains.kotlin:kotlin-bom:1.5.10
|    +--- org.jetbrains.kotlin:kotlin-stdlib:1.5.10 -> 1.4.31 (c)
|    +--- org.jetbrains.kotlin:kotlin-stdlib-jdk8:1.5.10 -> 1.5.0 (c)
|    +--- org.jetbrains.kotlin:kotlin-stdlib-common:1.5.10 -> 1.5.0 (c)
|    +--- org.jetbrains.kotlin:kotlin-reflect:1.5.10 -> 1.4.31 (c)
|    \--- org.jetbrains.kotlin:kotlin-stdlib-jdk7:1.5.10 -> 1.5.0 (c)

any suggestions to make this sane. one would think the BOM would be the appropriate approach.

dependencyInsight should tell you why

      Requested attributes not found in the selected variant:

      - Selected by rule

why is some transitive causing my app to not respect the platform i’m defining?

[tapchicoma]

probably better to ask this question in Gradle community slack

[christophsturm]

probably a bug in com.someotherapp:some-dep. maybe it uses enforcedPlatform too?

[Vampire]

Actually I was told by a Gradle guy, that you should normally always prefer platform and only in rare edge cases enforcedPlatform is appropriate.

[christophsturm]

gradle even warns when you publish a library that uses enforcedPlatform
