Here is my effective gradle configuration:

pkl.evaluators.register("evalPkl") {
                sourceModules.addAll("src/conf/default.pkl", "src/conf/production.pkl")

                outputFile.set(
                    File("${project.layout.buildDirectory.get()}/json/%{moduleName}.%{outputFormat}")
                )

                outputFormat.set("json")
            }

This issue was transient - only seen once thus far, but thought I would surface!

thus far, but thought I would surface!

Thanks for the report. Are you able to share the contents of default.pkl and production.pkl?

Sure! They are quite simple, this is a toy model 😄:

default.pkl

@ModuleInfo { minPklVersion = "0.25.2" }
module com.sample.ApplicationConfig

myMagicString: String = "Hello, world!"

production.pkl

amends "default.pkl"

myMagicString = "I'm in production!"

@bioball have y'all had a chance to look at this? We are still seeing this once in a while when leveraging the gradle plugin.

I haven't been able to reproduce this; this is passing pretty consistently for me.

How often does this happen for you?

Also, what Java version and Gradle version are you on?

Here are the versions. I would say this happens 1-2% of the time at most, quite infrequent.

Java: 11.0.16
Gradle: 8.1.1

Hm... this is pretty weird. I wrote a small script to call evalPkl over and over again, ran it for over an hour, and it didn't fail a single time.

Also, nothing about the code that you shared does anything that would cause consecutive executions to fail. There's no I/O asides from reading/writing to disk.
