# gradle

[Ciaran Sloan]

Hi there 👋🏼 Wondering if anyone can help me with a problem I'm struggling to work around. I have this super lightweight kotlin program that executes some script, thats a separate module in my android project. I can run this kotlin program via the command line: ./gradlew :myprogram:run however I want to run this as part of the pre-defined build gradle task. In other words, I always want this to run when someone tries to build the android app, and prior to that app compiling. Any suggestions on how I would do that? Some things I have tried 🧵

1. Trying to get the gradle task and make it depend on pre-build:

tasks.named(":myProgram:run").also { tasks.named("build").dependsOn(this) }

But I get an error that task :myProgram:run cannot be found.

2. Registering a new gradle task and trying to run the task on the command line:

tasks.register("runMyProgram") {
    exec {
        commandLine("./gradlew :myProgram:run")
    }
    tasks.named("build").dependsOn(this)
}

im making these declarations above in the projects root gradle file

[Adam S]

this code will first try to fetch the task that's defined in the subproject, but because the root build.gradle.kts file is evaluated first, Gradle won't have had a chance to create the :myProgram:run task yet

tasks.named(":myProgram:run").also { tasks.named("build").dependsOn(this) }

Instead you can add a dependency based on the task path

tasks.build {
  dependsOn(":myProgram:run")
}

(and using the generated Kotlin DSL accessor, tasks.build, for the build task)

oh nice, thanks this works perfectly!
