#install(plugins) ⇒ String Also known as: update

Installs a specific plugin or list of plugins. This method will install the latest available plugins that jenkins reports.

When the install action is issued, it gets the latest version of the plugin if the plugin is outdated.

Examples:

Installing a plugin and restart jenkins if required

>> @client.plugin.install "s3"
=> "302" # Response code from plugin installation POST
>> @client.plugin.restart_required?
=> true # A restart is required for the installation completion
>> @client.system.restart(true)
=> "302" # A force restart is performed

Parameters:

  • plugins (String, Array) —

    a single plugin or a list of plugins to be installed

Returns:

  • (String) —

    the HTTP code from the plugin install POST request
