你需要给gradle许可:

sudo gradle

Windows用户:

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同步失败:超时等待锁定守护进程地址注册表[…] 它目前正在被另一个Gradle实例使用。

Owner PID: 8080
Our PID: 89765
Owner Operation: ...
In order to unlock, just kill the owner process:

taskkill /PID 8080 /F
taskkill /PID 89765 /F

通过执行如下命令删除gradle缓存中的锁文件:

find ~/.gradle -type f -name "*.lock" -delete

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.
