android - 在 com.android.build.gradle.internal.api.ApplicationVariantImpl_Decorated@5635bcd2 上找不到属性 'packageApplication'

Question

这是我的 build.gradle:https://github.com/SnowdreamFramework/android-gradle-template/blob/master/config/android.gradle

当我尝试升级我的项目以使用 gradle 2.2.1 和类路径“com.android.tools.build:gradle:1.0.0-rc1”时，然后我编译并得到如下错误:

$ gradle wrappers --info --stacktrace

我们必须通过更改我们的代码来以这种方式访问​​ .packageApplication 来解决同样的问题:

 project.android.applicationVariants.all { variant ->
  variant = variant as ApplicationVariant // For type inference.
  variant.outputs.each { output ->
    output = output as ApkVariantOutput // For type inference.
    def packageTask = output.packageApplication
