Android Gradle构建中的意外节点Android Packaging

我想让我的项目使用gradle.问题是每次我尝试构建时,都会收到以下错误：

Error:Internal error: (java.lang.AssertionError) Unexpected node Android Packaging; nodes=[Module 'Serengeti' production, Resources for 'Serengeti' production, Resources for 'Serengeti' tests, Artifact 'Serengeti', gradle-resources-production:Serengeti, gradle-resources-test:Serengeti, Android Gradle Build Target]

我不知道这是什么意思.我找到了this,但它并没有真正有用……

这是我的build.gradle文件.这是我第一次使用gradle,所以如果有任何问题请指出.

我该如何解决这个错误？

解决方法:

找到了解决这个问题的方法.如果你去项目结构 – >模块 – > <您的项目> – &GT Android,你会注意到没有任何东西加载.它看起来像这样：

要解决此问题,请选择Android并单击“删除”(上面的红色虚线).然后单击添加(上面的绿色加号)并选择Android.单击确定,错误现在应该消失.
