Gradle失败消息后面通常跟着相关的进程id，所以应该是这样

Gradle sync failed: Timeout waiting to lock daemon addresses registry [...].
It is currently in use by another Gradle instance.

Owner PID: 1234
Our PID: 5678
Owner Operation: ...

为了解锁，只需杀死所有者进程:

sudo kill -9 1234

我可能会迟到，但看起来是一个快速有效的解决方案。

请执行以下步骤。

执行ps -ef | grep gradle 打开终端，移动到~/。gradle /缓存路径 执行find ~/。Gradle -type f -name "*。读取f时锁定“|”;做rm $f;完成 删除Android studio中的。gradle和。idea文件夹。

这是完成了。

在@Sean Stayns的回答中引用了一个场景，以防它能帮助到任何人:如果你把你的项目保存在谷歌Drive文件夹中——不要这样做。只需将项目移动到本地驱动器即可解决此问题。

In the case we were trying to solve, were were also getting the "It is currently in use by another Gradle instance" error and nothing we tried here worked. The process ID was unknown as well. It didn't immediately occur to me to ask where the project was being saved, so in case anyone new to Android Dev is saving their projects to a Google Drive folder, just move over to your local drive. I would have just left this as a comment in @Sean Stayns's answer, but I can't comment. Hopefully it benefits someone.

我在我的项目中也面临着同样的问题，但我通过使项目无效来解决这个问题，所以在android studio中遵循以下步骤

File -> Invalidate cache / Restart…

Android工作室将重新启动，您的问题应该得到解决。

Mac用户在第一次Gradle同步

我在使用IntelliJ从GitLab克隆时也遇到了同样的问题。 事实上，正如这里提到的:https://stackoverflow.com/a/53269914/2231299 需要指定内部硬盘。

在我的例子中，步骤如下:

•本地克隆

•等待1st gradle同步执行

•移动目录到外部硬盘

•在新位置重新打开项目，然后gradle应该工作正常，即使是在外部硬盘上。

评论: 如果文件看起来有一些变化，不要害怕重新提交。这可能只是缩进或换行的问题，因为你的外部磁盘可能与你原来的mac磁盘有不同的格式。

非常简单的解决方案:

不需要杀死Android Studio，只需杀死OpenJdkPlatform进程， 然后删除下面的.lock文件:

rootProject/.gradle/<version>/taskHistory
