This plugin controls the language of JenkinsNormally, Jenkins honors the browser's language preference if a translation is available for the preferred language, and uses the system default locale for messages during a build. This plugin allows you to:

  • override the system default locale to the language of your choice
  • ignore browser's language preference completely

This feature is sometimes convenient for multi-lingual environment.


Under Manage Jenkins > Configure System there should be a "Locale" section.

Here you can enter the "Default Language": this should be a language code or locale code like "fr" (for French), or "de_AT" (German, in Austria).

This value will be used by the system, for example, for messages that are printed to the log during a build (assuming that the Jenkins features and plugins that you're using have been translated into the specified language).

To additionally force this language on all users, overriding their browser language, you can check the "Ignore browser preference and force this language to all users" option.

    Looks like this plugin only works after you save the configuration each time Jenkins is restarted. If you restart Jenkins, the setting won't load by itself.

    Also you might want to provide some examples. I had to google to find out that ISO language settings don't work, but "ENGLISH" does.

    How to force plugin to use English? i thought it takes configuration from browser. Browser has English, but it shows content in Ukrainian, i don't know where from plugin took that configuration. When i sign out from google chrome account, it becomes English. But my account has English language and input... Where should i look to make it English?
