Hi! Please, about *1.4-M3*, I would be very grateful if someone could confirm if this a mistake from transitive dependencies:

```+--- org.jetbrains.kotlin:kotlin-scripting-compiler-embeddable:1.4-M3

|    \--- org.jetbrains.kotlin:kotlin-stdlib:1.4-M3 (*)```
According to <https://kotlinlang.org/eap/#build-details> the compatible version of `kotlinx.coroutines` is `1.3.7-1.4-M3`.

It also appears here: <https://kotlinlang.org/eap/configure-build-for-eap.html#adjust-versions-in-dependencies>

However, it's not found: <https://dl.bintray.com/kotlin/kotlin-eap/org/jetbrains/kotlinx/kotlinx-coroutines-core/1.3.7-1.4-M3/kotlinx-coroutines-core-1.3.7-1.4-M3.pom>

KotlinX libraries are not published to Kotlin repo, they have own repository
<https://dl.bintray.com/kotlin/kotlinx/|https://dl.bintray.com/kotlin/kotlinx/>

<https://dl.bintray.com/kotlin/kotlinx/org/jetbrains/kotlinx/kotlinx-coroutines-core/1.3.7-1.4-M3/kotlinx-coroutines-core-1.3.7-1.4-M3.pom|https://dl.bintray.com/kotlin/kotlinx/org/jetbrains/kotlinx/kotlinx-coroutines-core/1.3.7-1.4-M3/kotlinx-coroutines-core-1.3.7-1.4-M3.pom>

For JVM-only project you don’t have to use `-1.4-` version. It is all compatible in JVM.

Thank you so much <@U0BRK9HC5>, <@U2E974ELT> :raised_hands:

I managed to have just this difference about dependencies in a small project with a function and a test for that function (using plain JUnit). It works without the compiler plugin. However, when having that compiler plugin (which is compiled with `1.4-M3`) and the same source code (I'm not expecting any of the features from the compiler plugin), this error raises for the test class: `is compiled by a new Kotlin compiler backend and cannot be loaded by the old compiler`  Please, could you provide any clue to solve it? Thanks in advance!!
