通过运行构建时/gradlew使用下面的堆栈跟踪检查构建是否失败。我已经将面临这个问题的gradle更新为4.1，将AS更新为3.0。

出了什么问题：任务"：app:packageDefaultGlobalIndiaOnlyDebug"的执行失败。
无法创建目录C:\Users\<>\<>\<>\app\build\outputs\apk\defaultGlobalIndiaOnly\debug\C:\Users\<>\<>\<>\app\build\outputs\apk\defaultGlobalIndiaOnly\debug\C:\Users\<>\<>\<>\app\build\outputs\apk\defaultGlobalIndiaOnly\debug

尝试：使用
--info or --debug选项运行以获得更多日志输出。 -
例外情况是：

在构建时修改变量输出可能不起作用
使用变体API来操作变体输出被新插件打破了。它仍然适用于简单的任务，例如在构建时更改APK名称，如下所示：
// If you use each() to iterate through the variant objects,
// you need to start using all(). That's because each() iterates
// through only the objects that already exist during configuration time—
// but those object don't exist at configuration time with the new model.
// However, all() adapts to the new model by picking up object as they are
// added during execution.
android.applicationVariants.all { variant ->
variant.outputs.all {
outputFileName = "${variant.name}-${variant.versionName}.apk"
}
}
但是，涉及访问outputFile对象的更复杂的任务不再有效。这是因为在配置阶段不再创建特定于变体的任务。这导致插件无法提前知道其所有输出，但这也意味着更快的配置时间。
