升级AndroidStudio到3.4.1和gradle问题

Question

我已经将一个 Android 项目从 3.2 升级到 3.4.1，现在我遇到了 gradle 问题。

唯一的指示是顶部的栏

和事件日志中的消息。

Gradle sync failed: EventQueue.isDispatchThread()=false Toolkit.getEventQueue()=com.intellij.ide.IdeEventQueue@34e0424
            Current thread: Thread[ApplicationImpl pooled thread 19,4,Idea Thread Group] 388194366
            SystemEventQueueThread: Thread[AWT-EventQueue-0,6,Idea Thread Group] 847161915 (1 s 526 ms)

我已经清理了重建项目。

单击 Open Build View -> 没有任何反应。

日志文件包含：

如何分析这一点，如何获得有意义的消息。每次升级Androidstudio都被蒙蔽，真是令人沮丧。有没有办法通过控制台/终端执行同步？

更新 我可以限制这种情况。我发现只有当我添加一个 android 库（模块）时才会发生这种情况。我不明白为什么会这样。

更新 2 我找到了适合我的解决方案。升级过程将以下内容添加到我的 gradle 脚本中，这导致了问题。删除它后工作：

compileOptions.encoding = 'ISO-8859-1' productFlavors { }

这个问题仍然悬而未决。怎样才能专业的分析这类问题。我不得不在不知道任何上下文路径的情况下比较文件。
