Interesting It looks like if I use `kotlin stdlib` instead of `kotlin stdlib jdk8` there is no dependency on kotlin 1 2 41

darych · Answer

But now IDEA says that Kotlin is not configured If I choose Koltin with Java it adds `kotlin stdlib jdk8` again

< ilya gorbunov> Maybe you can help me please Why `kotlin stdlib jdk8` transitively use `kotlin stdlib` version 1 2 41 If it s necessary maybe warning should be removed

ilya.gorbunov · Answer

Perhaps these 1 2 41 versions of `kotlin stdlib` and `kotlin stdlib jdk7` are brought transitively by some other dependency Or their versions are specified in the `dependencyManagement` section explicitly or with some BOM import

darych · Answer

Will check it tomorrow once more But when I ran Maven dependency tree I saw kotlin 1 2 41 only under kotlin stdlib jdk8 Also I will check kotlin test I think it was used in project

< ilya gorbunov> I verified everything again Maven Dependency where I found 1 2 41 ``` INFO + org jetbrains kotlin kotlin test jar 1 3 21 test INFO | + org jetbrains kotlin kotlin test common jar 1 3 21 test INFO | | org jetbrains kotlin kotlin stdlib common jar 1 3 21 test INFO | org jetbrains kotlin kotlin stdlib jar 1 2 41 compile INFO | org jetbrains annotations jar 13 0 compile INFO + org mockito mockito core jar 2 15 0 test INFO | + net bytebuddy byte buddy jar 1 7 11 test INFO | + net bytebuddy byte buddy agent jar 1 7 11 test INFO | org objenesis objenesis jar 2 6 test INFO + org jetbrains kotlin kotlin stdlib jdk8 jar 1 3 21 compile INFO | org jetbrains kotlin kotlin stdlib jdk7 jar 1 2 41 compile ``` Dependencies declaration ``` lt kotlin version gt 1 3 21 lt kotlin version gt lt dependency gt lt groupId gt org jetbrains kotlin lt groupId gt lt artifactId gt kotlin test lt artifactId gt lt version gt $ kotlin version lt version gt lt scope gt test lt scope gt lt dependency gt lt dependency gt lt groupId gt org jetbrains kotlin lt groupId gt lt artifactId gt kotlin stdlib jdk8 lt artifactId gt lt version gt $ kotlin version lt version gt lt dependency gt ```
