Плагин Jenkins git -branch-source не может сканировать большую организацию

Question

Наш jenkins запускает версию 2.8.3 плагина github-branch-source, и у нас есть очень большая организация github, которая случайным образом не выполняет сканирование организации с ошибкой ниже:

Could not fetch sources from navigator org.jenkinsci.plugins.github_branch_source.GitHubSCMNavigator@531ba666

Я читал об обходном пути для отключения кеша в более старых версиях, установив:

org.jenkinsci.plugins.github_branch_source.GitHubSCMSource.cacheSize=0

Наш каталог кеша все еще заполняется, и я также видел комментарий об их установке:

GitHubServerConfig server = new GitHubServerConfig("my_github_credential_API"); 
server.setApiUrl(githubAPIurl)
server.setClientCacheSize(0) //<--See https://issues.jenkins-ci.org/browse/JENKINS-54126. Had to disable this one too to get this to stop happening

но я я не уверен, где это устанавливается? Возможно ли это обходное решение для версии 2.8.3?
