Problem after adding external dependencies in IntelliJ

Question

I'm starting a project using the KorGE library, and I would like to use Retrofit as XML parser. So I try to follow this guide, which seems fine, but I just poorly get stuck by adding the dependencies in the first step.

I already have the KorGE libraries included (I started from the template):

dependencies {
    classpath("com.soywiz.korlibs.korge.plugins:korge-gradle-plugin:$korgePluginVersion")
    classpath("com.soywiz.korlibs.klock:klock:1.6.1")
}

But when I try to includes the following dependencies, everything turns to hell when I load gradle changes (I guess this is the way I should declare them?):

classpath("com.squareup.retrofit:retrofit:2.4.0")
classpath("com.squareup.retrofit:converter-simplexml:2.4.0")

In the guide it seems that this dependencies are part of APIs, but I did not found anything different about declaration on the net. If I just copy-past it obviously doesn't work.

The errors I get after loading gradle changes:

java.lang.IllegalArgumentException: org.gradle.api.internal.initialization.DefaultClassLoaderScope@a2e5ac5 must be locked before it can be used to compute a classpath!
java.lang.IllegalArgumentException: project.classLoaderScope must be locked before querying the project schema

Thank you very much in advance for your help guys, and sorry for my noobiness.

Removing org.gradle.configureondemand=true in ~/.gradle/gradle.properties solved it for me.
