Unable to download the compiler

I am using the konan plugin (version 0.3) on Mac and I get an error:

It seems to try to download http://download.jetbrains.com/kotlin/native/kotlin-native-macos-0.3. I tried to download it in a browser and saw this:

[olonho]

Plugin with version 0.3 wasn't published yet. Please use released version 0.2 or wait few days for release of 0.3 plugin.

I also tried specifying version 2. I get a different error but it does not work either:

Also trying to download it from the browser I get an error:

Also, version 0.3 is the version suggested in https://github.com/JetBrains/kotlin-native/blob/master/GRADLE_PLUGIN.md

[ilmat192]

The 0.3 Gradle plugin is published and the compiler will be ready soon. But it looks like your issue relates to our dependency downloading and I'm going to investigate it.

[ilmat192]

A fix for the issue is ready (but is not merged into master yet). As a workaround you may remove $HOME/.konan/cache/.lock and try to rerun your build using Gradle plugin v0.2 and Kotlin/Native compiler v0.2.
