Qt創建者沒有為android構建項目

Question

我在Linux Ubuntu上配置了SDK，JDK，NDK。 但是當我嘗試為android構建我的項目時，會發生這些錯誤（所有編譯輸出）：

我該怎么做才能解決這個問題？ 提前致謝。

Answer 1

例外的關鍵是：

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，很久以前我們遇到了同樣的問題（使用gradle 1.x ）。 這是不是在自己的gradle或有人使用方式的限制（gradle這個 不是構建工具，這只是其中一個完整的構建過程中執行的次數十分之一的輔助）。
[Gradle]：Gradle-1.1：“等待120.0秒Gradle Worker N連接后超時。”包含類似的行為。

但是，根據： [Gradle]：同時運行多個gradle進程 ：

實際上，您可以合理安全地在同一個項目上運行兩個Gradle進程， 只要它們不會混淆彼此正在做的事情 （例如刪除創建的文件）。

擺脫這種情況的一種方法 （對我有用）：

• 找到保持文件鎖定的（ gradle ， java ）進程（可能是以前的構建掛起） - 你可以使用[man]：lsof找出鎖定文件的進程 - 並將其殺死
• 如果上面的步驟不夠，還要清理gradle的緩存
