android Jetpack Room 导出模式失败

Question

I refer to setting Export schemas in the documentation, But it failed, the error is as follows: The following is my Gradle configuration:

plugins {
    id 'com.android.application'
    id 'org.jetbrains.kotlin.android'

    // hilt
    id 'kotlin-kapt'
    id 'com.google.dagger.hilt.android'

}

android {
    namespace 'com.freedom.android'
    compileSdk 32

    defaultConfig {
        applicationId "com.freedom.android"
        minSdk 26
        targetSdk 32
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
        vectorDrawables {
            useSupportLibrary true
        }

        // Room
        javaCompileOptions {
            annotationProcessorOptions {
                compilerArgumentProviders(
                        new RoomSchemaArgProvider(new File(projectDir, "schemas"))
                )
            }
        }
    }

    buildTypes {

    }
    buildFeatures {

    }
    composeOptions {

        }
    }

    applicationVariants.all { variant ->
        variant.getRuntimeConfiguration().exclude group: 'com.google.code.findbugs', module: 'jsr305'

    debugImplementation "androidx.compose.ui:ui-test-manifest:$compose_ui_version"
}


// hilt
// Allow references to generated code
kapt {
    correctErrorTypes = true
}

// Room
class RoomSchemaArgProvider implements CommandLineArgumentProvider {

    @InputDirectory
    @PathSensitive(PathSensitivity.RELATIVE)
    File schemaDir

    RoomSchemaArgProvider(File schemaDir) {
        this.schemaDir = schemaDir
    }

    @Override
    Iterable<String> asArguments() {
        // Note: If you're using KSP, you should change the line below to return
        // ["room.schemaLocation=${schemaDir.path}"]
        return ["-Aroom.schemaLocation=${schemaDir.path}"]
    }
}

I am basically sure that it is an error caused by setting Export schemas. When I set exportSchema = false , the program can run normally. Sorry my settings file is a bit messy, but like I said, it works.

Convert string like this:

 return ["-Aroom.schemaLocation=${schemaDir.path}".toString()]
