Running the application using runProd ignores configuration file

[JFCote]

Play Version

Latest: 2.8.8

API

Java

Operating System

Windows 10

JDK

openjdk 11.0.11 2021-04-20
OpenJDK Runtime Environment AdoptOpenJDK-11.0.11+9 (build 11.0.11+9)
OpenJDK 64-Bit Server VM AdoptOpenJDK-11.0.11+9 (build 11.0.11+9, mixed mode)

Expected Behavior

1. In the command line, I run this: sbt -Dconfig.file=conf\my.conf runProd
2. The application starts in prod mode using the values in my provided configuration file (database, variables, etc..)

Actual Behavior

1. In the command line, I run this: sbt -Dconfig.file=conf\my.conf runProd
2. I receive errors that indicate that Play is not using my configuration at all (missing datasource, missing Log4j config, etc..).
3. For more information, see this Stack Overflow question: https://stackoverflow.com/questions/65905939/play-framework-runprod-not-accepting-custom-config-file

Please note that if I run sbt -Dconfig.file=conf\my.conf run, everything works fine but it's not in "prod mode" which I need for some testing. Looks like a bug, either in the documentation or in the code.

Is there anything I can do to help fix this bug? I can work hand in hands with developer's from the Play Framework if necessary (on slack or gitter, let me know). I just don't know how to code in Scala, so I can propose a PR... @gmethvin
Thanks

Try sbt run -Dconfig.resource=application.prod.conf runProd

@abteilung6 Thanks for the suggestion, but it doesn't work. I get exactly the same error. It's like the runProd completely ignore the configuration file passed in the command line.

I also had this issue, but using Intellij. I found a solution but this is a horrible user experience... it comes down to Intellij's run configurations being significantly different between the sbt run vs sbt runProd.

• RUN DEVELOPMENT (IDEA)
  • Tasks: run
  • VM Parameters: -Dconfig.file=./conf/dev.conf -Dlogger.file=./conf/logback-dev.xml
• RUN PRODUCTION (IDEA)
  • Tasks: THE QUOTES ARE REQUIRED!!! "runProd -Dlogger.resource=logback-dev.xml -Dconfig.resource=dev.conf"
  • VM Parameters: Emtpy

I'm not sure if it's Play or Intellij getting things mixed up. But correct usage is not clear.
