Using AGP 4.0.0, there is getCompileClasspath(null) on BaseVariant to return the compile classpath that I need to feed into another Gradle plugin.

What I figured however is that this classpath is missing the path where the compiled R.java, databinding classes or Kotlin synthetic accessor code is put at, effectively leading to compilation errors in the said other plugin.

It would be nice if BaseVariant would get the ability to offer the classpath to these resources.

The use case is an extension to the Detekt Gradle Plugin to allow Android modules leverage the type resolution feature of Detekt.

We need to intro a new API for this. getCompileClasspath(Object) is not meant for this.

Marked as fixed.

BaseVariant has been deprecated, but an API to access the varian't compile classpath has been added to com.android.build.api.variant.Component, starting with AGP 7.3.0-alpha03.

API:

/**
 * Access to the variant's compile classpath.
 *
 * The returned [FileCollection] should not be resolved until execution time.
 */
@get:Incubating
val compileClasspath: FileCollection

Example usage:

androidComponents {
    onVariants { variant ->
        project.tasks.register(
            variant.name + "Foo",
            FooTask::class.java
        ) {
            it.configurableFileCollectionInput.from(variant.compileClasspath)
        }
    }
}

Does this new API satisfy your use case?
