In my android multi-module project, I want to execute a Kotlin file to generare code.

My need is:

I have a multi-module project with one app module and lots of library modules.

There is a module named offlinedb. In that I have a main function file in it’s package com.framework.offlinedb.generator. It’s a simple main function that just calls a code gen kotlin class.

For that I used a gradle task. But the gradle task unable identify the main sourceset. I tried setting sourcesets etc.

gradle task:

tasks.register<JavaExec>("runCodeGenerator") {
    group = "code generation"
    description = "Runs the code generator in the offlinedb module"

    // Set the classpath to include the compiled classes of the offlinedb module
    classpath = project(":offlinedb").sourceSets["main"].runtimeClasspath
    // Set the main class to be executed
    mainClass.set("com.framework.offlinedb.generator.MainKt")

    // Pass any arguments if needed
    args = listOf("arg1", "arg2") // Replace with actual arguments if any
}

When i try to run the task I got this error:

* What went wrong:
A problem occurred configuring project ':offlinedb'.
> Could not create task ':offlinedb:runCodeGenerator'.
   > SourceSet with name 'main' not found.

When I try to list all sourceset, it returns empty list like no sourcesets at all.

How to fix this issue. Why I can’t find the “main” source set?.

I tried giving android.sourcesets[“main”], but I get “unable to locate the main class”

Please help me
