SyntaxError: missing ) after argument list

[SimonScholz]

Hi,

I just cloned this project.
I tried to build the project, but the following error occurs, when I do a ./gradlew build:

Starting a Gradle Daemon (subsequent builds will be faster)

It would be awesome if you could give me a hint on how to fix this issue.
Right now I am about to build a common library with the kotlin multiplatform approach and I´d love to make use of certain npm packages in the jsCommon SourceSet.

Thanks a lot in advance.
