Java 无法生成库项目Bintray Gradle-ClassNotFoundException

我仍在努力让我的gradle脚本工作，我已经解释了所有日志，似乎有一些类丢失了。这是留言

也许有人已经有了这样的问题，或者知道如何解决它？请帮忙，因为我已经不能让它整天工作了。 Thx提前。

我也在做同样的事情（将aar上传到bintray），我也有同样的问题

我知道它发生在gradle库中，所以我用这种方法将gradle版本从2.4.0更改为2.2.1

文件->项目结构（或触发热键

命令+；

）->单击对话框->渐变文本编辑框中输入2.2.1的左侧列表中的

项目

我用这种方法解决了这个错误。在文件中查找注释部分

希望这能帮助你

ps：如果您想使用gradle 2.4.0，您应该在项目root build.gradle的类路径中将android maven插件版本配置为1.3，如下所示：


dcendents:android maven gradle插件：1.3
似乎该类已被删除。尝试碰撞渐变版本。
