kotlinlang

I am having an issue with 1.0.1: `java.lang.NoClassDefFoundError: kotlinx/coroutines/SupervisorJobImpl`

when I run dependencies this is what I see:

```mvn dependency:tree | grep kotlin
[INFO] |     \- io.github.microutils:kotlin-logging:jar:1.6.20:compile
[INFO] |        \- io.github.microutils:kotlin-logging-common:jar:1.6.20:compile

[INFO] +- org.jetbrains.kotlin:kotlin-test:jar:1.3.10:test
[INFO] |  \- org.jetbrains.kotlin:kotlin-test-common:jar:1.3.10:test```

Please give more context. The target platform to begin with?

when I run a test it fails with this exception

when I excluded 1.2.71 it is ok, but I fail to understand why

Doesn't 1.2.71 take precedence because of another module relying on a dependency compiled with this version, without specifying the version itself?

1.2.71 was only for the stdlib the only version for coroutines that I see is 1.0.1

coroutines 1.0 probably needs a 1.3.x stdlib

Because this is the first Kotlin version that supports non-experimental coroutines
