Gradle lock exception: Gradle is used by another instance of Gradle

Question

I have a gradle weird issue that doesn't seem to be related to me by code. When I checked Jenkins, the assembly was broken by this exception:

Caused by: org.gradle.cache.internal.LockTimeoutException: Timeout waiting to lock buildscript class cache for build file '/Users/me/IdeaProjects/api/explore/build.gradle' (/Users/me/.gradle/caches/2.2/scripts/build_dr53ryug2vbnxp25bu47jmb6a/ProjectScript/buildscript). It is currently in use by another Gradle instance. Owner PID: unknown Our PID: 10869 Owner Operation: unknown Our operation: Initialize cache Lock file: /Users/me/.gradle/caches/2.2/scripts/build_dr53ryug2vbnxp25bu47jmb6a/ProjectScript/buildscript/cache.properties.lock at org.gradle.cache.internal.DefaultFileLockManager$DefaultFileLock.lock(DefaultFileLockManager.java:258) at org.gradle.cache.internal.DefaultFileLockManager$DefaultFileLock.<init>(DefaultFileLockManager.java:127) at org.gradle.cache.internal.DefaultFileLockManager.lock(DefaultFileLockManager.java:80) at org.gradle.cache.internal.DefaultCacheAccess.open(DefaultCacheAccess.java:99) at org.gradle.cache.internal.DefaultPersistentDirectoryStore.open(DefaultPersistentDirectoryStore.java:46) ... 44 more 

Any clues?

Thanks.

This happens when you start a new build, but your previous build has been paused. To fix this problem you need to delete the cache.properties.lock file
