A modern programming language that makes developers happier.

kotlinlang

When using the Kotlin Frontend plugin, I got this:
```A problem was found with the configuration of task ':koolui-test-js:webpack-bundle'.
&gt; File '/.../koolui-test-js/build/classes/kotlin/main/koolui-test-js.js' specified for property 'sourceFile' does not exist.```
The file most certainly exists, I've checked it and read it.  It's complete.
Any ideas?

Do you run Gradle task from the IDE or terminal? Maybe Gradle/Webpack has not enough permissions to read the file? Also Gradle and its plugins can be buggy sometimes so you can try newer/older version of Gradle.

That message left as mysteriously as it came.  Yeah, I'm guessing it was a permissions thing.
