This is a temporary repository containing a minimal reproduction of a bug which I am reporting to Renovate.

Its build.gradle contains the lines:

def kotlinModule(String name) {
"org.jetbrains.kotlin:kotlin-$name:$kotlinVersion"
}

dependencies {
kotlinScriptImplementation(kotlinModule("stdlib"))
}

This should result in Renovate looking up org.jetbrains.kotlin:kotlin-stdlib, but it fails to handle method parameter substitution correctly, and attempts to look up org.jetbrains.kotlin:kotlin-gradle-method-call-problem-demo, which of course fails:

DEBUG: Looking up org.jetbrains.kotlin:kotlin-gradle-method-call-problem-demo in repository https://repo.maven.apache.org/maven2/ (repository=michael-s-grant/gradle-method-call-problem-demo)

The problem is easy enough to work around in the short term, so not a showstopper, but it ought still to be fixed.
