Since Kotlin 1.4 no longer requires stating the stdlib-dependency in my gradle.kts-file, I removed it, but somehow gradle now imports the 1.3 version of kotlin-reflect (I don't even need kotlin-reflect).

w: Runtime JAR files in the classpath should have the same version. These files were found in the classpath:

w: Consider providing an explicit dependency on kotlin-reflect 1.4 to prevent strange errors
w: Some runtime JAR files in the classpath have an incompatible version. Consider removing them from the classpath

Probably a transitive dependency

[Arian Stolwijk]

Check the dependencies task

[Stephan Schroeder]

kotlin-reflect comes in as transitive dependency to kotlin-compiler-embeddable

kotlinCompilerClasspath
\--- org.jetbrains.kotlin:kotlin-compiler-embeddable:1.4.10
     +--- ...
     +--- org.jetbrains.kotlin:kotlin-reflect:1.4.10
     |    \--- org.jetbrains.kotlin:kotlin-stdlib:1.4.10 (*)
     +--- ...

kotlinKlibCommonizerClasspath
\--- org.jetbrains.kotlin:kotlin-klib-commonizer-embeddable:1.4.10
     +--- org.jetbrains.kotlin:kotlin-stdlib:1.4.10
     |    +--- ...
     \--- org.jetbrains.kotlin:kotlin-compiler-embeddable:1.4.10
          +--- ...
          +--- org.jetbrains.kotlin:kotlin-reflect:1.4.10
          |    \--- org.jetbrains.kotlin:kotlin-stdlib:1.4.10 (*)
          +--- ...

strangely enough, that dependency is to (the correct) version 1.4.10 of kotlin-reflect .
Does "gradlew clean build" have another log-level then "gradlew build"? The "Runtime JAR files in the classpath should have the same version." only shows up on "gradlew clean build".

Maybe the message is from Gradle itself (kotlin DSL compiler?)

[Robert Jaros]

I see the same warning for almost all my projects since migration to 1.4.x

[Robert Jaros]

But no other problems

[Stephan Schroeder]

I’m currently using latest gradle (6.6.1).
