Android 文件室新功能自动迁移错误：不兼容类型无法转换为列表<；迁移>；

我尝试使用Room自动迁移功能（），但当我尝试创建自动测试时，这不起作用。因此，我在TaskEntity的新类别列中添加了

@Entity(tableName = "tasks")
data class TaskEntity(
    @PrimaryKey
    val id: String,
    val title: String,
    val shortDescription: String,
    val fullDescription: String,
    val deadline: Date?,
    // This is new column
    @ColumnInfo(defaultValue = "DEFAULT")
    val category: TaskCategory
)

enum class TaskCategory {
    WORK, SPORT, SHOPPING, EDUCATION, DEFAULT
}

在此之后，我更新了数据库，如下所示：

@Database(
    version = 3,
    entities = [TaskEntity::class],
    autoMigrations = [AutoMigration(from = 2, to = 3)],
    exportSchema = true
)
@TypeConverters(DateConverter::class)
abstract class ToDoDatabase : RoomDatabase() {
    companion object {

        fun newTestDatabase(context: Context) = Room.inMemoryDatabaseBuilder(
            context,
            ToDoDatabase::class.java
        )
            .addMigrations(MIGRATION_1_2)
            .build()
    }

    abstract fun tasks(): TodoDao
}

val db = migrationTestHelper.runMigrationsAndValidate(
    DB_NAME,
    2,
    true,
    MIGRATION_1_2
)

其中3-是新版本，自动迁移（from=2，to=3）是新的自动迁移

我以前的迁徙

@VisibleForTesting
internal val MIGRATION_1_2 = object : Migration(1, 2) {
    override fun migrate(db: SupportSQLiteDatabase) {
        db.execSQL("ALTER TABLE tasks ADD COLUMN deadline INT")
    }
}

当我运行androidTest时，我得到了这样的错误：

error: incompatible types: List<ToDoDatabase_AutoMigration_2_3_Impl> cannot be converted to List<Migration>
    return Arrays.asList(new ToDoDatabase_AutoMigration_2_3_Impl());

}

还有一个问题是，我应该向migrationTestHelper.runMigrationsAndValidate添加什么？我试过这个

val db = migrationTestHelper.runMigrationsAndValidate(
    DB_NAME,
    3,
    true,
    ToDoDatabase_AutoMigration_2_3_Impl()
)

我添加了todatabase\u AutoMigration\u 2\u 3\u Impl（），但仍然不起作用。当我使用手动迁移时，看起来是这样的：

@Database(
    version = 3,
    entities = [TaskEntity::class],
    autoMigrations = [AutoMigration(from = 2, to = 3)],
    exportSchema = true
)
@TypeConverters(DateConverter::class)
abstract class ToDoDatabase : RoomDatabase() {
    companion object {

        fun newTestDatabase(context: Context) = Room.inMemoryDatabaseBuilder(
            context,
            ToDoDatabase::class.java
        )
            .addMigrations(MIGRATION_1_2)
            .build()
    }

    abstract fun tasks(): TodoDao
}

val db = migrationTestHelper.runMigrationsAndValidate(
    DB_NAME,
    2,
    true,
    MIGRATION_1_2
)
