在 Dao 类中使用 @Query时出现构建错误(房间持久性库)
我在我的项目中同时使用 java 和 kotlin，所以可能存在依赖问题，我尝试了不同的实现和 kapt，但没有运气。
我的依赖项(最后请参阅房间持久性库)

我的实体类
@Entity(tableName = "product")
public class Product
{
@PrimaryKey
@ColumnInfo(name = "id")
public Integer id;
@ColumnInfo(name = "category")
public String category;
@ColumnInfo(name = "name")
public String name;
@ColumnInfo(name = "price")
public Double price;
@ColumnInfo(name = "desc")
public String desc;
@ColumnInfo(name = "img_url")
public String img_url;
public Product(Integer id, String category, String name, Double price, String desc, String img_url) {
this.id = id;
this.category = category;
this.name = name;
this.price = price;
this.desc = desc;
this.img_url = img_url;
}
}
我的道班在不使用@Query时正在建立良好的状态， 但是当使用@Query时，会导致构建错误。
@Dao
public interface CartDao
{
@Query("SELECT * FROM product")
ArrayList<Product> getAllProduct();
@Delete
void delete(Product cart);
}
构建错误

@Dao
public interface CartDao
{
@Query("SELECT * FROM product")
ArrayList<Product> getAllProduct();
@Delete
void delete(Product cart);
}
代替 ArrayList 使用 List
我也遇到了同样的错误，运行干净构建，使缓存无效或尝试运行
gradlew assembleDebug
这将向您显示应用程序中的问题所在。
