A modern programming language that makes developers happier.

kotlinlang

I’m running into a weird issue. I have two Android modules in my project `:lib` and `:app`. `app` depends on `lib`. Both modules contain Java and Kotlin code. Additionally, the `lib` module includes a gradle script to upload the library to a maven repository. 

So far so good. The problem is the publishing script. It starts with 
```
apply plugin: 'maven-publish'

group = ‘com.group'
version = VERSION_NAME // defined in gradle.properties
… 
``` 
This for some reason results in an error and the compiler can’t find the Kotlin classes from the `lib` module in my `app` anymore. If I change the version to `version = ‘2.2’`, then everything works. But somehow references like `version = rootProject.ext.version` break the build. 

Does anyone know why this is happening? Only Kotlin classes are affected. I also checked that they bundled in the .aar file and they are.
