无法获取未知属性“汇编”

因此，昨天一切都很好，但是现在带有我的项目的Android Studio抛出此错误：

ERROR: Could not get unknown property 'assemble' for task ':patternjkh:assembleDebug' of type org.gradle.api.DefaultTask.

我搜索了很长时间，但没有找到适合我的解决方案。我的项目没有任何单词“汇编”（项目中的ctrl + shift + f）。

我也尝试过File-> Invalidate Caches / Restart and Clean-Rebuild Project。

我也试图从磁盘上删除项目，然后再次从bitbucket克隆它。但是没有任何帮助。

模块gradle：

尝试使用io.fabric.tools:gradle:1.26.1代替io.fabric.tools:gradle:1.+

尝试使用io.fabric.tools:gradle:1.26.1代替io.fabric.tools:gradle:1.+

---

这是解决方案。Fabric Gradle插件昨天更新为1.28.0：https://docs.fabric.io/android/changelog.html#fabric-gradle-plugin新版本似乎引起一些问题。

---

如果您将`apply plugin“ io.fabric”`添加到库模块（带有`apply plugin：&＃39;com.android.library&＃39;`），则看起来会发生此错误，但是如果将其应用于应用程序模块，则可以正常工作（使用`apply plugin：&＃39;com.android.application&＃39;`）
