我仍然试图让我的gradle脚本工作，我已经使用了所有日志，似乎缺少一些类。这是消息。

org.gradle.api.GradleScriptException: A problem occurred evaluating project ':horizontalrecyclerview'.

也许有人已经有过这样的问题或者知道解决问题的方法？请帮助，因为我不能整天工作。 Thx提前。

我正在做同样的事情（将我的aar上传到bintray）我也有同样的问题。

我知道它发生在gradle库中，所以我通过这种方式将我的gradle verion从2.4.0更改为2.2.1

档案 - ＆gt;项目结构（或触发热键command + ;） - ＆gt;点击对话框左侧列表中的Project - ＆gt;在Gradle textedit框中输入2.2.1。

我通过这种方式解决了这个错误。查看文件README.md中的注释部分。

希望这可以帮到你。

ps：如果你想使用gradle 2.4.0，你应该在项目根build.gradle的classpath中将android-maven-plugin版本配置为1.3：

com.github.dcendents:android-maven-gradle-plugin:1.3

无法构建库项目Bintray Gradle - ClassNotFoundException
