Dynamic Feature Module Manifest Placeholder Invalidates Build Cache

[stemas]

Describe the bug
The Gordon Gradle plugin creates a temporary file named PLACEHOLDER_DYNAMIC_MODULE_MANIFEST as a placeholder for the dynamicFeatureModuleManifest input property of GordonTestTask. However, because this is created as a temporary file, its name changes with each Gradle daemon process, which invalidates incremental builds and the build cache unnecessarily.

Impact
Build cache is invalidated on every daemon restart
Incremental builds don't work correctly
CI/CD pipelines and local development experience degraded performance

To Reproduce

1. Apply Gordon to an Android [app|library|feature] module.
2. no special setup
3. Run the following gradle task with these arguments: "--no-daemon"
4. All Tests are executed again without any change to the Tests or Code

Expected behavior
The second run of Gordon should not run any tests but be up-to-date instead.

Additional context
Workaround:

afterEvaluate {
    @Suppress("INVISIBLE_MEMBER", "INVISIBLE_REFERENCE")
    tasks.withType<com.banno.gordon.GordonTestTask>().configureEach {
        if(dynamicFeatureModuleManifest.get().asFile.name.startsWith("PLACEHOLDER_DYNAMIC_MODULE_MANIFEST")) {
            val placeholder = File(rootProject.layout.buildDirectory.get().asFile, "MY_PLACEHOLDER_DYNAMIC_MODULE_MANIFEST").apply { parentFile.mkdirs(); createNewFile() }
            dynamicFeatureModuleManifest.set(placeholder)
        }
    }
}
