Android的Gradle Sync错误：找不到属性'javaCompiler'

Question

我正在尝试使用cordova构建一个Android项目，但我一直收到一个gradle错误。我尝试从命令行或从Android Studio构建，但收到相同的消息：

* What went wrong:
A problem occurred configuring root project 'android'.
> A problem occurred configuring project ':CordovaLib'.
   > Could not find property 'javaCompiler' on com.android.build.gradle.internal.api.LibraryVariantImpl_Decorated@1aec405e.

gradle文件是由cordova生成的，所以我不确定它为什么不起作用。

这是我的build.gradle文件，删除了一些多余的注释：

// GENERATED FILE! DO NOT EDIT!

    repositories {

任何人都可以解释这个错误吗？我在我的gradle文件中没有看到任何名为javaCompiler的属性，所以我想知道这是否是内部的。

更新：当我直接用--stacktrace运行gradlew时，我得到以下输出：

这显然是gradle-android-aspectj-plugin中的缺陷，请参阅here。它还有一个fix checked in 11 days ago，似乎还没有发布。

我没有在build.gradle中看到此插件的明确使用，可能是您正在使用的其他项目或插件在内部使用它。

如果您的构建设置为使用最新版本的aspectj插件，为什么不从源代码构建gradle-android-aspectj-plugin到您的本地仓库并尝试重新构建项目。
