Uploading com.easy.demo.zip…
// api Easy.INSTANCE.easy_http_
// api(name: Easy.easy_http, ext: 'aar')
//直接依赖源码
api project(':library')

源码和远程依赖都试过

小伙子，在经过了大量的测试和验证后发现，这个问题其实就是混淆导致的问题，你发的 Demo 工程里面，debug 模式也开启了代码混淆模式，间接导致 HttpCallbackProxy 携带的泛型在编译过程中被擦除，解决的方案是在混淆规则中加入以下规则：

# 必须要加上此规则，否则会导致泛型解析失败
-keep public class * implements com.hjq.http.listener.OnHttpListener {
    *;
}

感谢轮子哥。
因为项目需要开启混淆，所以我将 com.hjq.http.listener 里面的接口都添加了混淆规则后，所有场景都正常了。
