How to create a target dependency with a specific configuration?

Hey everyone 👋

TL;DR: How can I create a dependency to another target using a specific configuration of that target?

I have the following scenario: My build target provides an additional prod configuration, which will run a production build of my project. So far so good: I can run this target using nx run app:build:prod.

I added a second target package, which depends on the build command:

{
  "build": {
    "configuration": {
      "prod": {}
    }
  },
  "package": {
    "dependsOn": [
      { "target": "build", "projects": "self" }
    ]
  }
}

Also this works perfectly: nx run app:package runs my build followed by the package target; Except that build is executed using its default configuration instead of prod.

I tried a few things like changing the target dependency to { "target": "build:prod", "projects": "self" } or passing the configuration via CLI (which fails obviously; package does not have a prod configuration ¯_(ツ)_/¯)... With no success so far.

How can I explicitly define the configuration for a target dependency?

I noticed that, once a configuration is given, depending targets having such a configuration are executed accordingly.

In order to make this work though, the "top most" project needs such a configuration as well, even if it is defined without any specific options.
