Jenkins build failure,Gradle build daemon disappeared unexpectedly

Question

My CI Server configuration is low.

If I use the gradle daemon to build project,It throw a error:

* What went wrong:
Gradle build daemon disappeared unexpectedly (it may have been killed or may have crashed)

Then, If I use the gradle-2.14.1 that default close gradle daemon,my task 'publish' is BUILD SUCCESS, but it will append other task to close daemon that BUILD FAILURE.

The message received from the daemon indicates that the daemon has disappeared
FAILURE: Build failed with an exception.

* What went wrong:
Gradle build daemon disappeared unexpectedly (it may have been killed or may have crashed)

Of course,if I run the gradle at my macbookpro, everything is OK.

I found the other way to solve the problem, run gradle --stop, then run gradle <task>. But it just work for simple task.

So, how to solve this problem?

The daemon is not intended for use on CI servers. There is a warning about that when you use it. – Haynes

Answer 1

Adding the flag -Dorg.gradle.daemon=false to the GRADLE_OPTS environment variable solved my issue in my case. Details can be found at : https://docs.gradle.org/current/userguide/gradle_daemon.html#sec:ways_to_disable_gradle_daemon

It is recommended to turn off gradle daemon on any CI server.

This appears not to be the case any longer - github.com/gradle/gradle/issues/2824 – Heydon

I've just run into this very same issue because of the CI task's container run out of memory. Nothing to do with the daemon itself. – Notable

Answer 3

Just discovered the following Jenkins Plugin: https://plugins.jenkins.io/gradle-daemon/ and with the plugin installed, the Daemon is not killed after the build, if it is still in use.
