It is currently in use by another Gradle instance

Question

I\'m new to Gradle build system. I want to do some basic functions on it. I\'m running/building it in command line. I am referring User guide. And, doing some simple tasks.<

Answer 1

Remove the lock files in the gradle cache by executing something like this:

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

Answer 2

I was stuck with this error and had to blow away the contents of my user's .gradle/caches/ folder and the contents of my project's .gradle/ folder to get going again.

Not sure what caused it, possibly a failed build that kept these files in a locked state?

Answer 3

For Windows machine:

Open Task Manager(Ctrl-Alt-Delete and check Process)

-> If you run two instance of android studio, Close One (End Task)

-> Then close OpenJDK Platform Binary

-> Gradle sync now on AndroidStudio and it will work now

Answer 4

For MAC machines

Please open the "Activity Monitor" and select the "memory" option and force quiet the Android studio and other running java processes, it will solve this issue.

Answer 5

For me, on a Mac, select File along top, then choose Invalidate Caches / Restart... done the trick.

A nice simple solution if it works for you too!

Answer 6

Just kill java.exe process fix my problem.

-- Edit --

if not fixed then:

• kill OpenJdkPlatform proccess.

if not fixed then:

• remove all ".lock" file from .gradle directory and sub directories (windows: C:\Users\Username\.gradle).

if not fixed then:

• rename or delete .gradle directory and try again.
