我应该怎么做才能修复它？提前谢谢。
答案 0 :(得分：0)
例外中的关键行是：
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，很久以前我们遇到了同样的问题（使用 gradle 1.x ）。它或者是 gradle 本身的限制或者它的使用方式（ gradle 不是 构建工具，它只是一个帮手在完整构建期间执行了十分之一次。）[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：

摆脱这种情况的一种方式（对我有用）：
