在Unity中使用moshi的ClassNotFoundException

Question

我创建了一个库,使用Square的moshi来处理它的JSON序列化和一些其他库,如RxJava,dagger等.
因为我想在Unity上使用它,我必须从我自己的库中导出AAR并在团结中添加moshi项目.

我使用Unity-jar-resolver工具在项目中添加我的库和依赖项.使用Gradle作为构建系统来制作项目我遇到了一些错误.

以下是有关错误的更多详细信息:

我使用Gradle是因为我需要申请multidex.这是我的配置:

buildscript {

    }

如果有人对此问题有任何解决方案,我会很高兴.

您不需要将注释处理器添加为库依赖项，就像 testCompile 一样。

只需将 gradle 中的所有内容添加为库 build.gradle 中的实现，然后尝试解决依赖关系。

注释处理器和 Codegen 库仅在编译时使用，仅此而已。因此，当您尝试使用已编译的版本时，您不需要它们。
