java - Android Parceler库: Unable to find generated Parcelable class

Question

我正在尝试在我的 Android Studio 项目中使用 Parceler 库。该项目有两个模块，一个是应用程序本身，另一个是包含各种帮助程序和通用实体的个人 Android 核心库。

但是，我在核心库中添加了 Parceler 依赖项，因为我也需要它，因此在库 build.gradle 中我添加了以下几行:

compile "org.parceler:parceler-api:1.0.4"
apt "org.parceler:parceler:1.0.4"

我没有在应用程序 build.gradle 文件中指定这些行，因为来自 Parceler 的依赖项将自动导入。

在我的应用程序中，我定义了一个必须可打包的实体，其实现是:

@Parcel
public class Course {
    public String name;

    public Course() { /*Required empty bean constructor*/ }

    public Course(String name) {
        this.name = name;
    }
}

但是当我尝试这样做时

Course[] courses = ...retrieved from server...
Parcelable p = Parcels.wrap(courses);

框架引发以下异常:

org.parceler.ParcelerRuntimeException: Unable to find generated Parcelable class for [Lit.bmsoftware.lotoapp.network.entity.Course;, verify that your class is configured properly and that the Parcelable class [Lit.bmsoftware.lotoapp.network.entity.Course;$$Parcelable is generated by Parceler.

我已经阅读了有关该异常的各种帖子，但找不到解决我的问题的方法。

有人可以帮助我吗？

提前致谢:)

编辑:build.gradle 文件

当前版本 (1.0.4) 不支持通过 Parcels 实用程序类创建 @Parcel 注解类的数组。相反，我建议使用 List:

List<Course> courses = ...retrieved from server...
Parcelable p = Parcels.wrap(courses);
