Features controlled by system properties

Hudson Features Controlled with System Properties

Hudson has several "hidden" features that can be enabled with system properties. System properties are defined by passing -D<property name>=<value> when you start Hudson. The following table lists the properties and the version of Hudson they were introduced in.

  • Property - Java property name
  • Default - Default value if not explicitly set
  • Version - The version of Hudson the property was introduced in
  • Notes - Other notes
