PureConfig is a “compiler-heavy” library and it seems like the resources provided to the Scala compiler via the Scala Gradle plugin are not enough for your use case. I was able to compile your project using Gradle by increasing the thread stack size, adding the following to build.gradle:

tasks.withType(ScalaCompile) {
    configure(scalaCompileOptions.forkOptions) {
        jvmArgs = ["-Xss2m"]
    }
}

@jcazevedo solution https://github.com/pureconfig/pureconfig/issues/391#issuecomment-401968537 has fixed it for me too. Since it took me a while to reach this page, here is the error message I had in my specific case to help people finding this solution, : could not find implicit value for evidence parameter of type pureconfig.ConfigReader[MyCaseClass]
