Delta coverage .kts setup SourceSet error

[Ascii91]

Describe the bug
We attempted to integrate the Delta Coverage plugin into our Android project using Kover 0.7.6. During the execution of a Gradle command, the following error occurred:

Execution failed for task ':app:deltaCoverageRandom'.
> Error while evaluating property 'coverageBinaryFiles' of task ':app:deltaCoverageRandom'.
   > Failed to query the value of task ':app:deltaCoverageRandom' property 'coverageBinaryFiles'.
      > SourceSet with name 'main' not found.

Environment

• Apple M3 Pro
• OS: MacOS 15.2 (24C101)
• Gradle version: 8.7.3
• Delta Coverage plugin version 3.1.1

Steps To Reproduce

1. Clone the sample project: DeltaCoverageDemo.
2. Run the Gradle command

./gradlew test deltaCoverageRandom

Expected Behavior
The task should complete without errors.

Logs

Execution failed for task ':app:deltaCoverageRandom'.
> Error while evaluating property 'coverageBinaryFiles' of task ':app:deltaCoverageRandom'.
   > Failed to query the value of task ':app:deltaCoverageRandom' property 'coverageBinaryFiles'.
      > SourceSet with name 'main' not found.

Additional context
The error does not occur when the project is configured using .gradle instead of .ktx.
Working configuration:

sourceSets {
    main {
        java { srcDirs = ["src/java"] }
        resources { srcDir "src/resources" }
    }
}
