<p class="MsoPlainText">It looked like we had problem with dynamic slaves because we tried to use gearman plugin with newest Jenkins LTS release (2.7.1).
<o:p></o:p></p>
<p class="MsoPlainText">We also had problems with sending Zuul parameter (ZUUL_PROJECT, ZUUL_COMMIT, etc.) to jenkins jobs. Those parameters could be seen in job description in build history:<o:p></o:p></p>

<p class="MsoPlainText">however were not passed as environment variables to job.<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">When we used Jenkins release 1.625.3 - the one suggested on plugin's wiki (<a href="https://wiki.jenkins-ci.org/display/JENKINS/Gearman+Plugin">https://wiki.jenkins-ci.org/display/JENKINS/Gearman+Plugin</a>) – everything started to work.
Now Gearman plugin sees dynamic slaves and is passing Zuul parameters to jobs.<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">Could you tell me if there is a plan to support newest Jenkins LTS releases in near future (for example 2.7.1) ?<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">On Zuul documentation page (<a href="http://docs.openstack.org/infra/system-config/zuul.html">http://docs.openstack.org/infra/system-config/zuul.html</a> ) we can see that openstack is moving away from Jenkins/Zuul to Ansible/Zuul for
launching jobs. <o:p></o:p></p>
<p class="MsoPlainText">Will Gearman plugin be still developed in such case? Are you planning to support this plugin in long term period?<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">Do you have any knowledge that future releases of Zuul (3.x.x) will also you gearman deamon to handle job executions so that we could use it with gearman plugin?<o:p></o:p></p>
