In my first build of android, I encountered build error. Error message is in below.
FAILURE: Build failed with an exception. * What went wrong: Timeout waiting to lock Build Output Cleanup Cache (/path/to/my/app/platforms/android/.gradle/buildOutputCleanup). It is currently in use by another Gradle instance. Owner PID: unknown Our PID: 16022 Owner Operation: unknown Our operation: Lock file: /path/to/my/app/platforms/android/.gradle/buildOutputCleanup/cache.properties.lock
I killed the process and deleted all *.lock file and build several times, but I encountered same error. Please advice to me.
