Qt创建者没有为android构建项目

Question

我在Linux上配置了SDK、JDK、NDK。但是，当我试图为android构建我的项目时，会出现这些错误(全部是编译输出)：

我该怎么做才能修好它？提前谢谢。

Answer 1

例外情况中的关键行是：

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，我们很久以前也遇到过同样的问题(使用gradle 1.x)。这要么是gradle本身的限制，要么是它的使用方式的限制(gradle不是--构建工具，它只是一个在完整构建过程中执行十分之一的助手)。

[ Gradle ]：Gradle-1.1：“等待120.0秒后，Gradle Worker N连接的超时。”包含类似的行为。

但是，根据：[ gradle ]：并发运行多个分级进程

实际上，您可以在同一个项目上合理地运行两个Gradle进程，只要它们不干扰彼此正在做的事情(例如删除创建的文件)，就可以安全地运行。

One way以摆脱这种情况(这对我有用)：

• 查找保持文件锁定的(gradle，java)进程(可能是以前的构建挂起的)--您可以使用[人]：查找锁定文件的进程，并将其关闭。
• 如果上面的步骤还不够，也要清理gradle的缓存
