Hi, I'm getting some warning everytime I compile the buildSrc (I am using precompiled kotlin scripts for configuring our projects):

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

Kotlin 1.3.60 is newer than 1.3.50 packaged with gradle 6. But why is there this kotlin-stdlib-jre7-1.1.0.jar? Does anybody know?

[pawegio]

have you tried gradle 6.0.1?

[trathschlag]

I just tried it. Unfortunately the warning is still there.

imho, one of dependencies is pulling kotlin 1.1.0 stdlib. You could check it via build scan.

[trathschlag]

Thanks, I found it. I couldn't do a build scan, but I could run ../gradlew :dependencies inside buildSrc and it revealed that some old and unsused plugin pulled in the library.

Gradle 6.X becomes more strict regarding dependencies version. That is why you saw it after update
