Какие переменные среды передаются Jenkins при использовании подключаемого модуля Gerrit Trigger?

Для начала у меня был скрипт оболочки сборки Jenkins, выгружающий все переменные среды с GERRIT в имени:

GERRIT_PATCHSET_UPLOADER=\"Alan Thompson\" <[email protected]>
GERRIT_PATCHSET_REVISION=eec3b0b65fcdf30872befa2e9ace06e96cd487b4
GERRIT_CHANGE_ID=Ieec3b0b65fcdf30872befa2e9ace06e96cd487b4
GERRIT_PATCHSET_NUMBER=1
[email protected]
GERRIT_CHANGE_NUMBER=8
GERRIT_CHANGE_OWNER=\"Alan Thompson\" <[email protected]>
GERRIT_REFSPEC=refs/changes/08/8/1
GERRIT_EVENT_TYPE=change-merged
GERRIT_EVENT_ACCOUNT=\"Alan Thompson\" <[email protected]>
GERRIT_CHANGE_SUBJECT=toast:  this is great with coffee
GERRIT_CHANGE_OWNER_NAME=Alan Thompson
GERRIT_PROJECT=kitchen
GERRIT_EVENT_HASH=-1357519550
GERRIT_BRANCH=master
[email protected]
[email protected]
GERRIT_CHANGE_URL=http://localhost/8
GERRIT_PATCHSET_UPLOADER_NAME=Alan Thompson
GERRIT_EVENT_ACCOUNT_NAME=Alan Thompson

Точный ответ можно найти в источнике здесь, и есть по крайней мере некоторые комментарии к исходному коду, описывающие, что это значит.

Спасибо за вашу долю. Я нашел GerritTriggerParameters.java на GitHub. и я пишу сценарий оболочки для вывода переменных gerrit-trigger.

Очень важная информация для тех, кто, как и я, бился головой о монитор. В мае 2016 года было выпущено обновление безопасности для Jenkins, которое не допускает произвольные параметры, если они не определены в конфигурации задания:

https://wiki.jenkins-ci.org/display/JENKINS/Plugins+affected+by+fix+for+SECURITY-170

Параметры, определенные Аланом Томпсоном, верны, но вам также необходимо определить эти параметры в конфигурации задания.

запустить задание оболочки всего одной строкой:

env | grep GERRIT_

и просмотрите журнал сборки

Они перечислены в тексте справки для триггера; маленький вопросительный знак рядом с флажком триггера события Gerrit на странице конфигурации задания.
