Qt的创造者不会构建android的项目

我已经在Linux Ubuntu上配置了SDK，JDK，NDK。但是当我试图建立我的项目为Android，论文出现错误（编译所有输出）：

我应该做些什么来解决呢？提前致谢。

Answer 1

异常中的关键行是：

Exception in thread "main" java.lang.RuntimeException: Timeout of 120000 reached waiting for exclusive access to file: /home/muhammad/.gradle/wrapper/dists/gradle-3.4-bin/aeufj4znodijbvwfbsq3044r0/gradle-3.4-bin.zip` 

在我以前的雇主，我们有同样的问题在很久以前（使用gradle这个1.x的）。它可能是gradle本身或其使用方式的限制（gradle不是构建工具，它只是在完整构建过程中执行十分之一次的帮手）。
[Gradle]: Gradle-1.1: “Timeout after waiting 120.0 seconds for Gradle Worker N to connect.”包含类似的行为。

但是，根据：[Gradle]: Running multiple gradle processes concurrently：

实际上，你可以运行两个摇篮在同一项目上合理的安全处理，只要他们不什么对方是做混乱（如删除创建的文件）。

一种方式获得摆脱这种局面的（即工作对我来说）：

• 找到（gradle这个，的java）过程中，保持锁定的文件（也许这是一个以前的版本挂起） - 你可以用[man]: lsof找出锁定文件的过程 - 并杀死它
• 如果上面的步骤还不够，还可以干净gradle的缓存
