To configure
the package version settings for a class or trigger:
- Edit either a class or trigger, and click Version Settings.
- Select a Version for each managed package
referenced by the class or trigger. This version of the managed package
will continue to be used by the class or trigger if later versions
of the managed package are installed, unless you manually update the
version setting. To add an installed managed
package to the settings list, select a package from the list of available
packages. The list is only displayed if you have an installed managed
package that is not already associated with the class or trigger.
- Click Save.
Note the following when working with package version settings:
- If you save an Apex class or trigger that references a managed package without specifying
a version of the managed package, the Apex class or trigger is associated with the latest installed version
of the managed package by default.
- You cannot Remove a class or trigger's
version setting for a managed package if the package is referenced
in the class or trigger. Use Show Dependencies to find where a managed package is referenced by a class or trigger.
