kotlinlang

trying to use the new 1.4-M3 but getting this error `Plugin [id: 'org.jetbrains.kotlin.plugin.serialization', version: '1.4-M3'] was not found in any of the following sources:` …i added `maven ("<https://dl.bintray.com/kotlin/kotlin-eap>")` to my `repositories` but still no luck, anybody know how to fix?

```* What went wrong:
Plugin [id: 'org.jetbrains.kotlin.plugin.serialization', version: '1.4-M3'] was not found in any of the following sources:

- Gradle Core Plugins (plugin is not in 'org.gradle' namespace)
- Plugin Repositories (could not resolve plugin artifact 'org.jetbrains.kotlin.plugin.serialization:org.jetbrains.kotlin.plugin.serialization.gradle.plugin:1.4-M3')
  Searched in the following repositories:
    Gradle Central Plugin Repository```

looks like it’s not actually looking in the repo i specified :confused:

```pluginManagement {
    repositories {
        mavenCentral()
        gradlePluginPortal()
        maven("<https://dl.bintray.com/kotlin/kotlin-eap>")
    }
}```


thank you!  had to tweak slightly for my old-school settings.gradle but worked great

in case anybody else comes across this and also has a settings.gradle:
```pluginManagement {
    repositories {
        mavenCentral()
        gradlePluginPortal()
        maven { url "<https://dl.bintray.com/kotlin/kotlin-eap>" }
    }
}```
