try removing

@Inject constructor()

then it tells me the constructor should be annotated with

@Inject

looks like a constructor injection issue - try

abstract class GenerateFederatedGraphqlSchema : Exec() {

what is

graphql

in

register()

? if you're not taking any parameters then there shouldn't be any given

from a past gist that’s a const string - the task name.

ah right, I usually use

registering

which derives the name automatically

yeah, it's just a string

that’s not right. with no constructor parameters there’s no need to annotate. Have many custom tasks w/ no constructor params (not even sure how to provide params to inject into the constructor - guess you could do the canned services I suppose).

I mean.. idk, but that's the error it gives me

remove not just the annotation - the bogus, empty

constructor()

didn't happen until I added an @TaskAction... and converted those method's to val's

the vals are fine.

too*

ah, figured out what it is

lovely. Looking closer at this - it doesn’t need to subclass Exec, should inject ExecOperations

this works (and doesn't require

@Inject constructor()

):

@TaskAction
    fun action() {
        workingDir = project.file("../../")
        project.exec {
            commandLine = mutableListOf("yarn", "generate:graphql")
        }
        project.exec {
            commandLine = mutableListOf("yarn", "prettier", "--write", outputSchema.get().asFile.path)
        }
    }

Something like this:

abstract class GenerateFederatedGraphqlSchema : DefaultTask {
  @get:Inject
  protected abstract val execOps : ExecOperations

  @get:Inject
  protected abstract val layout : ProjectLayout

  @get:SkipWhenEmpty
  @get:InputFiles
  @get:PathSensitive(PathSensitivity.RELATIVE)
  abstract val sourceFiles: ConfigurableFileCollection

  @get:OutputFile
  abstract val outputSchema: RegularFileProperty

  @TaskAction
  fun action() {
    workingDir = layout.projectDirectory.file("../../")
    execOps.exec {
      commandLine = mutableListOf("yarn", "generate:graphql")
    }
    execOps.exec {
      commandLine = mutableListOf("yarn", "prettier", "--write", outputSchema.get().asFile.path)
    }
  }
}

you'd have seen the error immediately if this were defined outside of a build script

indeed. confused me for a moment seeing a random

file

in a custom task…

k, giving it a go...
